First of all, electric fireplaces are designed to create a cozy and comfortable atmosphere in a house or apartment. The dimensions of electric fireplaces are one of the most important criteria that must be taken into account when choosing.

The quality of the placement of the model in the interior of the room allocated for its installation and placement directly depends on how correctly the dimensions of electric fireplaces are chosen. In this article, you can familiarize yourself in detail with the choice of model dimensions and view the best photo of the selection.

The smallest installations

The dimensions of an electric fireplace can be very small. Such installations are characterized by the following features:

Peculiarities	Description
Mobility	The dimensions of an electric fireplace can be very small. In this case, the structure easily fits on the eighth of one square meter in an apartment or house.
Versatility	The smallest models are suitable for installation in any room. In the living room with large area you can install several of these fireplaces at once. In small and medium-sized rooms, as a rule, only one hearth is placed. Due to their overall dimensions, such heating units are easily transported, transported and rearranged from meta to place. Some hearths can be placed on a table, cabinet, shelf or any other surface.
Availability	The miniature size of an electric fireplace makes them quite inexpensive and affordable. The devices have simplified functionality and simple control.

It is interesting to know: fireplaces with electric dimensions which are quite mobile can have both the simplest and the most innovative, full functionality. The most popular and expensive models are equipped with sound, light and visual effects, and can also have a built-in humidifier. In general, the price for electric fireplaces varies from 6,000 to 250,000 rubles.

Miniature fireplaces have small size and mass

Medium size electric fireplaces

Miniature models are followed by medium-sized devices. Electric fireplaces, the dimensions of which allow them to be installed and mounted in more diverse places, have advanced functionality and can be placed as follows:

Near walls (side structure);
Sit on the floor (island);
Embedded or hung on walls (imitate paintings).

This model due to its shape, it looks more voluminous

Multimedia portals are in good harmony with modern and high-tech style

Tip: in order for medium-sized installations to look more advantageous, it is recommended to place them on plain surfaces and planes. Harmonize well pendant models With various techniques... The sizes of medium-sized electric fireplaces allow placement in offices and rooms ranging from 20 to 40 squares. Small fireplaces are installed not only in living rooms, but also in kitchens and dining rooms (they are mounted in kitchen sets and columns).

It is interesting to know: the cost of such structures, depending on their functionality, placement method, manufacturer and materials of manufacture, ranges from 11,000 to 260,000 rubles. Units with simple visual support have more low price, unlike those whose functionality provides for the presence of a humidifier and imitation of logs burning in the hearth.

For a more detailed acquaintance with the dimensions of electric fireplaces and their design features, we recommend watching the video in this article.

Large fireplaces

An electric fireplace whose dimensions do not allow you to easily move it from place to place and change its location, belongs to the category of large ones. Due to their massiveness and bulkiness, such models have a fairly high cost, a wide variety of functionality.

Important: since such large heating units take up a lot of space, they are intended for installation in rooms with an area of 50 square or more. When choosing, be sure to consider the style of both the hearth itself and the room.

Corner structures have their own advantages and allow

Interesting to know: an electric fireplace whose dimensions are more than 70 and 50 centimeters (length and height) are classified as large. Such foci have a similar appearance to their smaller counterparts. The location is more varied and can be not only built-in, island and wall-mounted, but also suspended, angular.

The large size of the electric fireplace gives it the following features and advantages:

The large size of the electric fireplace makes it more visible and allows, through its correct and location, to advantageously place the necessary accents and achieve complete harmony;
Large functionality allows, if necessary, to adjust the power level, turn on and off the sound and visual arrangement, enjoy the effect of the most realistic flame (vaporization function), perform simultaneous heating and humidification of the room. The most expensive models are able to synchronize with PCs, smartphones and other equipment, they have the ability remote control;
The large size of the electric fireplace allows you to achieve the maximum possible heat transfer;
If you wish, you can choose a stylish portal to the purchased hearth. Such framing will favorably emphasize the existing style and shadow with a good, winning addition to your interior;
Built-in models are installed in a specially prepared niche in the wall. Despite their massiveness and rather large dimensions, such fireplaces allow you to profitably save free space, which is important even for rooms with a large area.

Tip: the size of the portal for the electric fireplace depends on the selected hearth. In order for each element to be ideally combined with each other, it is recommended to buy a ready-made fireplace set or pick up both parts from one seller. If you did not find the portal in the required style, you can make it yourself. This frame is based on metal profiles and fireproof drywall. Further finishing and cladding is at your discretion.

Important: when buying a product, not only the size of electric fireplaces is important, but also the type of its hearth. It can be both closed and open. Open models are less effective, the hearth of closed installations is usually equipped with a special screen or heat-resistant transparent glass (when simulating fire with backlights, halogen lamps and steam).

The price for such products starts from 28,000 rubles. and depends on the functionality, capabilities and finishing materials of the hearth, portal. The most expensive models are finished in gold, precious stones, rare natural minerals.

Criterias of choice

In order to make the right choice and decide on the purchase of a particular model, you will need the following instructions, which indicate the main selection criteria:

When choosing the dimensions of the hearth, pay attention to the size of your house, apartment and the specific room in which you are going to perform the installation. The smaller the footage of the room, the smaller the size of the proposed fireplace will be. Very large installations will look out of proportion and take up a lot of space. Small fireplaces in the interior of a large apartment will, on the contrary, be lost and will not attract due attention;
Do not select the design according to the power parameters. As a rule, such electrical units are capable of performing the role of an exclusively additional source of heating. With dimensions of 40 by 50 centimeters or more, the installation will be able to heat a room, the total area of which does not exceed 20 square meters;
When choosing sizes, consider the following advice from planners and designers, which is that the size of the fireplace is no more than 1 unit from 50 units of the room itself. For example, with a room size of 25 squares, the heating unit should occupy about 0.50 squares of free space;
Large hearths are suitable for installation in spacious studios and living rooms.

The dimensions of electric fireplaces can be both very miniature and quite large. When buying, it is important to take into account not only your personal wishes and preferences, but also the area of your house, office, apartment or entertainment facility. Functionality, style and arrangement are no less important. Right choice and the ratio of each of these parameters will allow you to achieve coziness, comfort and harmony.

Compliance with the exact dimensions of the fireplace is the key to its reliability. Despite the variety of appearance, purchased products have standardized sizes. For high-quality combustion and output of the derivative of the process, an oxygen supply is required. At the same time, its quantity should ensure the removal of smoke from the furnace exclusively into the chimney.

Peculiarities

The structural features of a classic fireplace suggest that air is supplied to the firebox through the fireplace window. Experts have calculated that the optimal traction speed for a heater of any size should be less than 0.25 m / s. In practice, it is difficult to measure the thrust speed. Before the fireplace is lighted, its presence can be determined by fluctuations in the flame of a lit paper sheet. The user of the fireplace can only be convinced of the sufficiency of the traction force in practice.

Its presence or absence is also influenced by such external parameters as:

indoor and outdoor temperatures;
chimney condition;
type, volume and dryness of fuel.

The main condition for the operability of the fireplace is the observance of the basic parameters, their ratios in the design of the heating unit. Optimal parameters heating structure will allow organizing high-performance operation of the device. The ideal result can be achieved if the basic requirements are followed.

To avoid violations in the device, the fireplace must comply with the following tasks:

provide heat;
remove smoke from the room;
provide correct amount air in the combustion chamber.

The aforementioned standardization of dimensions does not lead to the same appearance for all devices. Among all the parameters of the device, there are those that really affect its performance.

Certain dimensions must be embodied in projects exactly. These include:

linear dimensions of the combustion hole;
chimney dimensions;
distance from the floor to the first edge of the window;
the location of the tooth;
parameters of the pipe width in the area of the tooth.

Other parameters do not affect the operation of the device, but only determine the difference between the devices. The dimensions of the portal are often associated with the dimensions of the furnace. They are associated with specific location parameters.

There is no absolute value: the dimensions of the device are closely related to the volume of the heated room. When incarnating own project try using the table below. It indicates the conditions for the normal operation of the device. Wizards use similar tables.

The data presented in the table is formed from certain values. The area of the room is always the starting point for calculating a fireplace. In accordance with this value, the size of the fireplace insert is determined. For this, the area of the room is divided by 50. Next, the dimensions of the furnace are determined by calculating the ratio of width and height. Calculations are expressed as a fractional value of 2/3.

The rate of removal of combustion products is interrelated with the depth of the combustion chamber.

With a deepened combustion chamber, the gas extraction rate increases. This is bad, since the heat in the room with such an outcome cannot be expected. With a shallow furnace, a good pulling force will not be achieved. Combustion products will begin to flow into the room. The depth of the furnace must be related to the height of the windows. Two-thirds of the value of the latter is proportional sizes verified over the years.

To make it clearer, we will give an example of the calculated indicators of a fireplace for a living room with an area of 28 sq. meters. To begin with, 28 must be divided by 50, we get 0.56. These are the parameters of the combustion window. The area of the combustion hole will be 0.61x0.92 = 0.5612 sq. m., the depth of the fuel chamber is (610x2) / 3 = 406.7 mm. The calculated indicator can be rounded off: you get a fuel chamber with a depth of 40 cm.

In addition to the firebox, a standard fireplace includes a ventilation duct (chimney). The dimensions of the ventilation duct openings are usually 1/8, 1/15 of the dimensions of the combustion box. This takes into account the length of the chimney. The allowed height is 10 meters. In this case, the structure should not be too low. Most optimal height the chimney structure is 4-5 m. The device is usually supplemented with knee bends.

To remove carbon monoxide, a special device called a tooth is installed.

The required chimney height is reached with a specially laid out foundation. Often, the pedestal is not associated with the foundation of the house. For the fireplace, it also serves as a safety platform. Therefore, it is often made protruding beyond the hearth by a few centimeters.

The fuel chamber is located on a pedestal made of non-combustible materials, the height of which can be from 30 to 40 cm. An increase in the height of the pedestal is allowed design features chimney. In some cases, a place under the pedestal is organized for storing firewood. Calculations of the position of the firebox, as well as the pedestal itself, include the features of the flooring material.

These parameters are considered during the design phase of the fireplace.

Kinds

The creation of a fireplace project is aimed at realizing original decor rooms adding home comfort and comfort. Modern market offers a wide variety of devices. The fireplace is allowed to be installed even in the most small room... It can be compactly placed in the corner of the room, or consider the option of a device built into a wall niche. Despite all the variety of options, even decorative models are chosen in relation to the dimensions of the room space.

So that the electric fireplace does not look bulky, its dimensions should not be more than 1/25 of the area. For example, for a room of 20 sq. the parameters of the electrical device are 0.8 m. electric model does not require storage space for logs, as well as pipes for the removal of combustion products. Similarly, the dimensions of the fireplace insert of a decorative unit or biofireplace are calculated.

When choosing these structures, it is also necessary to calculate the dimensions.

For the firebox of a biofireplace, the calculation of the portal will require the preparation of a special drawing in several projections. In this case, the finished portal must correspond to the selected firebox (firebox). Drawing execution is allowed using special programs that are installed on the PC. The shape of the thermal openings of such fireplaces can be different: it is no secret that the appearance of the fireplace in the house worries people in the first place.

To calculate the values, it is necessary to add the width of the side decorations to the width of the firebox as well as portal consoles. A firebox is added to the height of the firebox, mantel and other decorative parts. The calculations take into account the depth of the firebox. Stores often offer options for furnaces with ready-made portals. At home, all that remains is to install the firebox into the finished portal.

Besides different types imitations the market offers many options for classic metal fireplaces.

Popular types of metal fireplaces are:

suspended;
built-in;
with an open firebox;

on gas or with a wood-burning stove;
with or without doors.

The parameters of ready-made fireplaces for a particular room are selected in accordance with the instructions of the passport for the device. Power is usually indicated in the passport, the dimensions are determined by the heated volume of the room. The power calculation is related to the area of the house, as well as the height of the ceilings. The minimum power of the installation is calculated as follows: the area of the building is multiplied by the height of the ceiling and divided by 20. In terms of selection general view fireplace device, you can be guided by your own preferences.

Of all the heating units in use today, the fireplace is perhaps the oldest. It takes its origin from an ordinary, open hearth. To improve traction and prevent smoke from filling the room, they began to build a pipe for the hearth. In ancient times, almost all buildings were made of wood and to ensure safety, the hearths were covered with stones, so a fireplace appeared.

Interior decoration

Nowadays, fireplaces have become very popular, they are installed not only in a private house. Modern bio fireplaces have made it possible to use this unit in ordinary apartments... But such structures are intended primarily for decorative purposes, but today we want to talk about real ones, working on wood fuel, for the installation of which it is required to build a foundation.

Both heats and dries

Regardless of what kind of fireplace is installed in the house, many perceive it as an attribute of decorating the room and do not think why this unit has survived almost unchanged from ancient times to the present day. But he is an excellent ventilation device at home.

With its help, you can ventilate and dry the room, while this operation is performed in a very short term, for which more than one heating device cannot cope with this task. This unit is very good to use in rooms where there is no central, constant heating.

For example, after lighting a fireplace in a private house used for periodical residence, you will dry and warm up the cottage very quickly. (See the fireplace stove for a summer residence)

Size matters

But one must understand that all these advantages are effective only if the sizes of fireplaces for the house are chosen correctly. It's no secret that when arranging it, many care first of all about appearance, location in the room. And only in the last place they turn their attention to such an important fact as the size of the fireplace.

Today we will just talk about how to correctly calculate a fireplace for a house and make a design drawing based on the existing tasks in order to ensure maximum efficiency.

Important aspects: what needs to be considered?

When you start designing a fireplace for a home, make a drawing (see Drawings of corner fireplaces) and perform calculations based on the size of the room. Firewood can be burned both in a special metal basket and on the grate, or maybe just on the bottom of the firebox.

Our regular readers know that for normal combustion, in addition to fuel, a sufficient supply of air is required.

in the case when the fuel burns on a flat hearth and the dimensions of the fireplace inserts are the same, combustion on the grate will be much more efficient;
however, in both cases, the dimensions will be identical.

The fact is that the use of a grate provides an additional air flow, in this case it is possible to reduce the size of the furnace without losing efficiency.

Double effect - warmth plus ventilation

Since we started talking about air supply and the possibility of its intake different ways, it should be added that in some cases air can be taken not only from the room in which the fireplace is located, but also from next room or even from the basement.

Such a device allows you to achieve several positive aspects at the same time:

By taking air from the basement, you will significantly increase its ventilation, which in itself is a good result.
If air is taken from another room in the house, no vacuum is created in the room where the fireplace is located, and its absence does not allow cold air from outside to enter the heated room. The effect is obvious - the room heats up very quickly with minimum cost fuel.
If it is necessary to ventilate the heated room, the external air intake is simply shut off. In this case, combustion air begins to flow from the room where it is located, the room is ventilated.

We carry out calculations

But we did not answer the main question - how to calculate the size of the fireplace and make a drawing?

First of all, the furnace hole

First of all, it is necessary to determine the size of the fireplace insert. To accurately calculate the size of the firebox, it is necessary to measure the room in which the fireplace will be installed. Let's start by determining the size of the firebox opening. The ratio of the combustion hole to the area of the room is 1:50 .

In order to make it clearer, let's take a room of a certain size and calculate correct sizes fireplaces that can be installed in it.

The area of the room is 20 m².
We carry out the calculation - 20/50 = 0.4 m2, or 4000 cm², we have decided on the size of the furnace hole, this data can be entered into our drawing.

Determining width and height

In our case, it turns out 51X77 cm or 510X770 mm.
It is quite easy to double-check this data, 51X77 = 3927 cm2, nearly 4000 cm2, as you can see, our calculations coincide with the requirements.

The important part is depth

The depth is 2/3 of the height.
We already know the height, we have it equal 510 mm.
We make a calculation - (510/3) * 2 = 340 mm - we have determined the depth.

This depth is ideal for a fireplace of this size.

if you increase the depth, the heat will just start flying out into the chimney;
reducing this size will lead to smoke in the room.

For those who, for some reason, do not want to independently carry out all measurements and calculations, below we give a table of the main parameters that will help make a drawing. From them, knowing the area of \ u200b \ u200bthe room, you can determine the standard dimensions of the fireplace that you require.

Chimney - special attention

When designing, it is important to correctly calculate the size of the chimney for the fireplace. It is calculated based on the area of the portal and should be in 10-15 times smaller than it.

Advice: knowing the dimensions of the fireplace inserts, you, of course, can calculate the size of the chimney, but you should know that this is a very responsible event. If you do not have much experience in this area, it is better to entrust it to a professional, because no one has canceled such a concept as reverse thrust. Carbon monoxide poisoning is deadly! Remember this!

You can get more detailed information about chimneys by reading the corresponding articles on our portal. There, various chimneys are described in detail, including chimney flues.

Dimensions and material - direct relationship

When setting up a fireplace, the dimensions of the chimney and firebox are not the only ones you need to know. For example, someone is more interested in the question - how many bricks do you need for a fireplace? The question is not idle and quite understandable.

But before answering it, we want to add a little to all of the above. In our article, considering the methods of calculating and determining the size of this or that part, we did not mention the materials. Why are we talking about this just now? Because this is directly related to the question of the number of bricks.

Choice of location and dimensions

Previously, we calculated the furnace dimensions, the fireplace and its dimensions directly depend on the material from which it will be made. Knowing the material, you can fairly accurately calculate the dimensions and determine the place for the future fireplace.

On our pages, we have already described how to choose a place, so we will not repeat ourselves. The only thing that needs to be added: knowing the placement rules and correctly calculating the dimensions, you will be able to install this unit in the best possible way.

Foundation

After determining the dimensions of the furnace and chimney, you should calculate what the foundation should be.

Build a foundation based on weight future design... If the weight of the fireplace is less than 700 kg, then the foundation can be omitted, however, often, the weight of the structure is much higher, so the foundation is necessary.

When building a medium-sized fireplace, as a rule, a foundation is made with a depth of 0.75 to 1 meter. These figures are true if it is planned to live in the house permanently and the soil under it will not freeze. When building a fireplace on summer cottage, the foundation must be buried to the depth of soil freezing.

Please note: it is extremely important that the foundation of the fireplace and the foundation of the house do not have dressings, as these structures can give different settlements, which will lead to the formation of cracks.

Major mistakes

Unfortunately, this is not always the case. In some cases, one or several rules are violated at once:

The correct size fireplace for the particular room.
Correct placement in compliance with its dimensions for a particular room.

Knowledge is power

This knowledge is optional in the case when you will be engaged in construction with your own hands, they will be useful to you when you hire outside workers for construction.

Nowadays, there are "specialists" who are able to build something that looks and works well at first glance, but on deep examination turns out to be another flaw. The knowledge will help you to exercise the right control over the construction work in your home.

The number of bricks - we count the orders

As for the number of bricks, we will not give detailed calculations for one simple reason - they will not be useful to you at all. Indeed, for each specific case, a completely different calculation is required.

Nevertheless, we will try to explain in a nutshell how you can roughly determine the number of bricks. Knowing the size of the fireplace, the dimensions of the brick and the thickness of the seam, you can fairly accurately calculate its amount.

In any case, when arranging fireplaces, its dimensions are transferred to orders.
Having orders on hand, use them to count the number of bricks.
Don't forget about the seams. The thickness of the seam plays an important role in this case.

We have already described how to properly arrange the seams in the articles on masonry on our resource, so we will not repeat ourselves. By adding the number of bricks in all orders, you get total... If the base is made of bricks, do not forget about it.

Our advice: add more to the amount of bricks you get. 10% .

Put together

Having made a drawing of the fireplace, you probably made sure that compliance with the basic parameters is extremely important in its construction, and appearance plays a secondary role in this case.

Dimensions of the fireplace in the house: calculation, according to the area

If speak about self-creation fireplace, it is imperative to know the parameters to which it must correspond. More specifically, you need to draw up drawings of the combustion part, chimney, ordering and, of course, write down the materials that will be required in the process.

So, for example, to calculate the size of the furnace hole, you need to know the size of your room. The ratio of the firebox and the area of the room should correspond to 1 to 50. For example, if you established that the area of the room is 25 m 2, then we count 25 to 50 and get 0.5 m 2, this is the size of your future furnace hole. As for the width and height, they are determined by a ratio of 2 to 3. That is, taking into account the size of our firebox, it can be calculated that the width will be 80, and the height 63. Incorrect calculations are fraught with impaired traction, room smoke and poor heat transfer.

If we talk about the chimney, then it depends on the area of the portal, its size should be 15 times smaller. If this is not taken into account in the calculation, then the generated carbon monoxide gases will flow into the room, and this is life-threatening.

The third thing to pay attention to is order. It is necessary to complete the drawings as accurately as possible. We carry out the order on paper and be sure to indicate the materials that will be needed, in what quantity and for what purpose. The order may look like a standard table, where all dimensions are indicated. The plan should also indicate the depth, width and height. Also in the drawings, the rows should be numbered, in the future this will help you not to get lost when laying.

If we talk about the material, then, for example, a brick is calculated based on the order, but its exact amount cannot be determined, only an approximate one. To determine the exact amount, you need to take into account how much brick will be used for masonry and joint joints, add all this to an intermediate count.

We count the materials. In the process of preparing drawings and acquiring material, you need to know not only the future dimensions of your fireplace, but also how many bricks will be needed to build it. This approach will help to calculate all the possible costs of laying out the object.

Fireplace calculation: size advantages

Regardless of which model of the fireplace will be installed, many people perceive it only as a decoration, and, unfortunately, do not even think about why this installation has not changed after so long.
after all, it is the fireplace that can become an excellent attribute for room ventilation. With its help, you can not only ventilate, but also dry the room. Moreover, all these actions can be performed in a very short time, many heating devices it is beyond the power. Fireplaces, it is profitable solution for those premises in which there is no central, constant heating. For example, if you light a fireplace in a country house that is rarely used, you can quickly dry and warm up the house.

It should be noted that all these advantages are available only if all sizes were correct, compared.

It is no secret that when installing a fireplace in the house, most people worry first of all about its appearance and location in the room, and only then about this important fact as sizes. In order for the fireplace to perform at full power all its functions, you need to correctly make calculations, drawings that will meet all the tasks. Only in this case the installation will work with maximum efficiency.

What should be the height of the fireplace

In order to adjust the height of the fireplace, in most cases, special-purpose bolts are used, which are installed on the legs, or special supports - stands are used. In order to adjust the required distance from the firebox brick installation to the floor, you need to lay several lines of bricks.

To create the desired height, you must familiarize yourself with the following requirements:

The distance to the floor should be from 300 to 400 mm, this is the best indicator;
If there is a container for storing firewood under the firebox, this distance must be increased;
In the process of calculating the location of the bottom of the firebox, take into account the design of your floor with its components.

All these points should be taken into account even at the planning stage and drawing up drawings of the future heating system. All dimensions must be clearly measured so as not to get unacceptable errors in the future.

We calculate a fireplace with an open hearth: important aspects of creation

When organizing the construction of any fireplace, one must not forget about important recommendations specialists. The most important thing is to follow all dimensions, since they play an important role in the characteristics of the fireplace. When will you start preliminary calculations, follow all formulas and consider possible factors and aspects.

Among the important aspects, the following can be highlighted:

The size of the insert of almost any fireplace should not be less than 25 cm, and not more than 40 cm. Such dimensions are considered optimal for domestic-type fireplaces with an average power. These varieties are the most common. If we talk about a stove for a bath, then here the width of the firebox can be slightly more than 40 cm.
If you doubt the correctness of the calculations for your fireplace design, you can check them in a simple way. The width of the firebox must necessarily match the width of your firebox door.
Please note that the difference in size will significantly reduce the heat flux, and the fuel will burn much more slowly than it should be. In any case, the wrong dimensions will reduce the use and efficiency of your fireplace.

Experts always try to pay special attention to the firebox, because its parameters are the most important indicator. Minimum size the firebox should be 80 cm, maximum 100 cm. Very often, when constructing a fireplace, it is impossible to achieve such an indicator, and the way out of this situation is to increase the level of the afterburner. If the size does not match, then all the combustible gases that were formed in the process will not burn.

How to calculate the dimensions of the fireplace?

A fireplace is often a full-fledged source of heat (even if it is auxiliary, not the main one). The dimensions of this heating structure for a room with an area of 20 m 2 are as follows:

the area of the furnace should vary within 0.4 m 2;
furnace opening height - 52 cm, width - 78 cm;
the depth of the hearth should be 34-35 cm.

The cross-sectional area and the height of the chimney are equally important values that require a separate and especially careful calculation. A fireplace, the dimensions of which are incorrectly calculated, can pose a real threat to human health and life, which lies in the possibility of combustion products and carbon monoxide entering the room. The optimal ratio of the cross-sectional area of the chimney and the fuel hole is considered to be 1/10, however, the standard size of the fireplace is not an axiom, since each individual case requires an individual accurate calculation.

Sizing wood-burning fireplaces

Wood-burning fireplaces are constructions where all family members often gather with pleasure during cold autumn and winter evenings. The sound of crackling firewood and the sight of dancing flames inevitably create a unique atmosphere of tranquility and comfort. Real brick fireplaces are not a cheap pleasure, so many home craftsmen have a desire to do this work on their own. Certainly, this occupation cannot be called simple, but if everything is done in accordance with the rules, then the result will certainly be positive.

The fireplace includes the following mandatory components:

firebox;
smoke chamber;
chimney.

The size of each element must have the required ratio with the dimensions of the heated room.

So, for example, the area of the combustion hole in relation to the total area of the room should be 1:50. In this case, the height and width are related as 2: 3, and the depth and height of the furnace varies from 1: 2 to 2: 3.

The combustion area has the greatest influence on the size of the smoke hole. The required level of draft can be provided as follows: the area of the furnace should be 8-15 times more area section of the chimney. Moreover, if you plan to install round tube, then you can choose a smaller section than if the chimney was square or rectangular.

Material selection

Wood-burning fireplaces are best built from solid red fireclay bricks.

The quality of this material can be checked by the following indicators:

the color should be uniform and dense;
a hammer blow on a brick should "return" with a clear and clear sound.

In addition, you will need:

sand, the grain of which should not exceed 1.5 mm;
Cambrian clay, and you can also use brown or dark red;
crushed stone - 3-6 mm;
Portland cement grade 300.

You also need to purchase:

smoke damper;
fireplace screen;
grate.

Foundation

Before starting to build a home, you need to take care of a separate foundation. The depth of the pit should be 60 cm, and the width should be 10 cm higher than the dimensions of the future foundation.

The bottom should be covered with crushed stone and tamped thoroughly to maintain horizontal position.

The installed formwork must be filled up broken brick, stones or crushed stone, and then fill with thoroughly mixed cement mortar... The top of the foundation should be leveled and checked for levelness. After 7 days, you can start building the fireplace.

Features of masonry fireplace

Before starting the construction of such a useful invention as a fireplace, the dimensions of which were determined by us earlier, waterproofing should be provided. This will require roofing material, laid in 2 layers. Laying should start at the corners. In this case, you need to constantly monitor the level. To give designs original view, you can lay the bottom row on the edge, and all subsequent ones - flat. Outside solid rows require the use of a trowel or trowel. The smoke collector or firebox should be carried out manually, as this helps to detect small stones in the solution.

It is important to remember that when erecting a smoke collector and a firebox, the fireplace stove requires the removal of excess solution with a damp cloth. We must not forget that the inner wall is not plastering. The seam must be thin, otherwise it can quickly crack. Modern fireplaces need to tie the seams on half a brick in each row.

The lining of the firebox and the outer wall should not be connected, otherwise, due to frequent temperature changes, the masonry may be disturbed.

About modern fireplaces

Each person is pleased to hear the sound of a crackling tree and feel the warmth of a flame. Similar feelings can be enjoyed not only in nature, but also in own home... Brick fireplaces are capable of making dreams come true. The main tasks of this equipment include not only the creation of comfort and coziness at home, but also its heating.

Modern fireplaces can consume as fuel:

coal;
natural wood;
electrical energy.

There are many ready-made fireplaces on the market. The difference is made by open and closed types firebox. In addition, a fireplace stove can have a closed combined heating system or an open one, where the type of firebox directly depends on the wishes of the buyer.

A modern fireplace is a versatile and practical design that can be installed in any convenient place.

Fireplace as a design element

The fireplace is an excellent design solution that can emphasize the overall style of the room. For its registration can be used classic style, modern, country or any other pleasing to the owner.

Heating with a fireplace requires accessories such as a poker, tongs, ash scoop and grate. Truth, modern society pays much more attention to the emotional and psychological role of this construction. That is why it is not recommended to install a fireplace in a small room, near a door or in an aisle. Perfect option - comfortable chairs located in a spacious room, a special stand for equipment and a neat bench under your feet.

Country style, or rustic: unpretentiousness against the background of modest charm

The etymology of the word "rustic" speaks of the most characteristic features this style - deliberate "roughness", "roughness", stylization under the rustic interior (in another way, this style is called country). The desire of our ancestors to bring an element of aesthetics into the arrangement of their primitive home gave rise to this architectural trend, which subsequently began to develop so widely and comprehensively.

Country style is characterized by natural details, components and materials, emphasized "rough" processing and open hearth shape. The most suitable materials are: shell rock, sandstone, tuff stone, etc.

On the exquisite excesses of a baroque fireplace

The Baroque style, which originated in Europe during the Middle Ages, is a reflection of taste in Renaissance architecture. This direction is also appropriate in such a case as fireplace styles. It is distinguished by: the dynamism of the image, excessive pomp and luxury, a certain illusory form and lines, pomp and decorativeness.

Modern style

Lovers of the Art Nouveau style will easily abandon most of the decor elements in favor of an unusual color experiment. This direction is characterized by: oblong, foam-like, constructive combination of stone and metal parts, as well as the presence of ceramics or glass in the cladding. The style adherents are unusual geometric shapes, restraint, brevity, as well as unconventional design solutions. As a worthy accompaniment to a fireplace in the Art Nouveau style, one can single out a large abstractionist or landscape painting, minimally decorated furniture, walls covered with asymmetrical lines and muted colors.

Determining the size of the fireplace

With the choice of material, as a rule, there are no problems; it is a matter of personal preferences, financial capabilities, as well as the structure of the building. So, for example, the installation of a brick fireplace in a typical city apartment will require serious reconstruction of floors, repairs and approvals from supervisory authorities. Therefore, apartment owners often prefer electric or bio fireplaces that do not require the installation of a chimney, performing rather decorative function... If the main purpose of the fireplace is to heat a private house, then the best choice will become a metal or brick fireplace with a wood or gas stove.

Naturally, with all the variety of models, corner fireplaces have a completely different sizes... For decorative fireplaces, the size is determined based on the overall design and layout of the house, and for heating fireplace it is also necessary to take into account the area of the heated rooms.

Decorative corner fireplace - maximum dimensions

The dimensions of a do-it-yourself corner false fireplace are chosen based on the size of the room. So that the structure does not look bulky, the area of the corner fireplace should not exceed 1/25 of the area of the room. So, for a living room of 20 square meters, the optimal area of the fireplace should be no more than 0.8 meters, and the length of its sides adjacent to the walls should not exceed 1.2 meters.

The design can be made lighter and not cluttering up the space, but at the same time functional, if you attach shelves to the raised fireplace on both sides. These shelves can act as coasters for books, souvenirs and knickknacks.

Similarly, the dimensions of the portal for a built-in electric firebox or biofireplace are calculated, but in this case, it is also necessary to take into account the installation dimensions of the firebox, which are indicated in the passport. For example, for a biofireplace firebox with dimensions of 625x628x267 mm, the drawing of which is shown in the figure, it is necessary to select the dimensions of the portal.

Overall dimensions of the firebox

In order to calculate its width, it is necessary to add to the width of the firebox the width of the side frames and consoles of the portal, and to the height - the height of the firebox, mantelpiece, decorative elements... The depth of the firebox must also be taken into account. Let's assume the width of the side frames is 250 mm on both sides, the height of the firebox is 400 mm, and the height of the cornice and mantelpiece is 300 mm. As a result, we get the width of the fireplace 1125 mm, height - 1328 mm. The width of the side walls of the portal, taking into account the depth of the furnace, will be 250-300 mm. The length of the sides adjoining the walls for a symmetrical fireplace is calculated as the width of the portal divided by 1.4 - in our case it will be equal to 0.8 m.

The easiest way is to take the drawing of the furnace in three projections and draw the drawing of the portal directly on it, taking into account all the distances, and then calculate the required dimensions. You can also purchase a ready-made portal, the dimensions of which correspond to the firebox you have chosen - the specialists of the shopping center will help you with this.

Metal fireplace

Metal fireplaces are of several types: floor-standing, in a finished case with decorative trim, or built-in fire chambers. They can operate on wood, pellets, gas, depending on the selected model. The dimensions of such fireplaces for a particular room are determined by the heated volume of air - this parameter is called power and is indicated in the passport for the fireplace. To choose a suitable fireplace, you need to calculate the area of the house that you plan to heat, multiply it by the height of the ceilings, and divide the resulting volume by 20. You will get minimum value the power of the fireplace you need for heating.

For example, for country house with an area of 60 square meters with a ceiling height of 2.7 m, the volume of the room will be approximately 160 cubic meters. You need to divide this figure by 20, you get the required power of 8 kW. For such a house, a fireplace stove with a power of 9 kW, shown in the figure, is quite suitable. Its dimensions are shown in the drawing.

For a built-in firebox after choosing a model with required power the calculation of the dimensions of the portal is carried out in the same way as for decorative fireplace... An exception is the case when the firebox is placed in a prepared brick fireplace body. For such a fireplace, when calculating, it is necessary to take into account the standard dimensions of the brick in order to avoid additional adjustment.

Dimensions of a brick corner fireplace

The most difficult case, requiring careful calculations, is the construction of a wood-burning brick corner fireplace. In this case, it is necessary to carry out a preliminary calculation of the minimum dimensions of the furnace and chimney, depending on the heated room, and then adapt the results to the standard dimensions of the brick.

To calculate, you need to know the area of the heated room or house. This indicator is divided by 100, the result is the area of the furnace. The firebox in a corner fireplace is made triangular or trapezoidal with a narrowing towards the back wall - this shape contributes to better heat transfer.

For a firebox with a triangular bottom, the width of the front part is found as follows: remove Square root from the area value and multiply it by two. The depth of both sides is determined by dividing the width by 1.4. The height of the fireplace insert for classic corner fireplaces is usually slightly larger than its width. The diameter of the smoke hole should be within 1: 10… 1: 15 of the furnace area. For example, you need to calculate the dimensions of a brick corner fireplace for heating a living room of 30 square meters. To do this, divide the area by 100, get the value 0.3 square meters... Find the width of the firebox: take the square root of 0.3 and multiply the value by 2, you get 1.1 m - this width corresponds to about 4 bricks. The depth of the sides will be 1.1 / 1.4 = 0.78 m - 3 bricks.

To determine the dimensions of a trapezoidal firebox, you can use a ready-made table. Based on the results of the calculations, a suitable fireplace model is selected from the ones shown in the figures below, and the fireplace is laid in accordance with the order.

Other important fireplace sizes

If your fireplace is installed on a separate foundation, some requirements must be observed when pouring it:

The concrete base should be 5-10 cm larger than the fireplace area on each side;
The foundation of the fireplace cannot be rigidly fastened to the foundation of the house, it must be at least 10 cm away from it, and this distance after the concrete has hardened must be covered with a sand pillow;
The height of the foundation should be below the level of the finished floor by 2 rows of masonry, that is, by 15 cm. Before starting the construction of the fireplace, the foundation is waterproofed with roofing material in two layers and the base is laid out of the brick according to the scheme of the first two rows of ordering on cement mortar.

It is also necessary to observe fire-prevention distances of 25 cm from the chimney to the floor beams and walls, and secure the combustible structures near the walls of the fireplace itself with thick foil.

It is equally important to correctly design the area of the smoke hole and the height of the chimney in order to ensure good draft and exclude smoke from the room. The area of the smoke hole should be within 1: 10… 1: 15 of the furnace area. For example, the area of one brick is 0.03 square meters, which corresponds to the area of the furnace 0.3-0.45 square meters. The height of the straight part of the chimney should be such as to provide a stable draft - usually it is done in the range of 3-5 meters. If the height of the chimney at your fireplace turns out to be higher, you need to provide bends with bends, otherwise the draft will be too strong, and the firewood will burn out instantly. The height of the pipe above the level of the roof depends on its location relative to the ridge, it must correspond to the scheme.

As you can see from the article, it is not difficult to build a corner fireplace, the dimensions of which are calculated in advance. To better know the technology of building decorative or corner wood-burning fireplaces from bricks, we recommend that you familiarize yourself with other articles on our website.

Fireplace, contrary to popular belief, the structure is not very complicated. Having information about the design of the fireplace and the ratio of its elements, even a beginner can independently fold correct fireplace ... Of course, for this you need to have at least basic masonry skills.

The main elements of the fireplace are the firebox and the chimney. Correct construction of these elements will ensure that there is no smoke when burning, which is the main task when fireplace construction.

The construction of the fireplace begins with the fireplace table - this is the base of the fireplace at floor level. The fireplace table is constructed from refractory bricks or concrete. In front of the fireplace there is a pre-furnace area, which is laid out with refractory bricks and is designed to protect the floor from fire. In this case, jointing should be done. An additional steel sheet is often laid on the pre-furnace site. The dimensions of the pre-furnace site are at least half a meter in front and 30 centimeters on the sides of the portal. The portal is called the open part of the fireplace, that is, the framing of the firebox.

Pod is the place where firewood is directly burned. It is located on the fireplace table and should be above floor level. It rises underneath so that the process of burning firewood does not depend on a draft. Underneath is also laid out with refractory bricks. Often installed on the under grate, and already on it combustion occurs.

An ash-pan is located between the hearth and the pre-furnace platform, which is designed to collect unburned firewood and ash. A removable ash pan is installed in the ash pan for easy cleaning. Also, the ash-pan provides additional air flow to the burning wood. Often, a special decorative grate is installed in the portal opening, which prevents firewood from falling out of the firebox.

The firebox is laid out with refractory bricks, followed by lining with fireclay bricks - a special finish to ensure protection brickwork from destruction due high temperatures... Although many fireplace craftsmen prefer to lay out the firebox directly from fire-resistant fireclay bricks, which makes it possible to do without subsequent lining. Fireclay brick it also increases the heat transfer of the fireplace.

To enhance the heat-reflecting effect, the rear wall of the firebox is often clad with steel sheet or cast iron plate. Top part the rear wall of the firebox is made at an inclination of 12 degrees forward. In this case, heat flows are reflected and directed to the floor.

The fireplace portal is made square, rectangular or semicircular. Above the portal is installed mantel, which acts as a stand for various little things... A mantel can be made from ordinary concrete, as well as from more noble materials - granite or marble.

A smoke collector is located above the firebox, which prevents cold air from the atmosphere from entering the fireplace. The smoke collector is often made in a pyramidal shape. Back wall The smoke box is equipped with a so-called smoke tooth, which serves to form a gas threshold. It prevents air currents and traps soot. Not far from the smoke tooth, a special window is provided for cleaning the chimney from soot.

At a height of two meters from the floor, a conventional stove valve is installed, with which the traction force is regulated. It closes after the fireplace has been extinguished and prevents cold air from entering the room.

The height of the chimney of the fireplace should be at least 5 meters, and the higher it is, the better. Usually, the pipe is made in such a way that it protrudes a couple of meters above the roof ridge. This is to ensure good traction.

Fireplace proportions

When building a fireplace, the proportions must be observed. For small room it is not necessary to build a large fireplace, in this case it can cause drafts and it will be cool in the room. A fireplace that is too small should not be built either, it will not be able to heat the room.

To comply with the proportions, the portal area is made 50 times less area premises, and the area of the hearth should be 70% of the area of the portal. The chimney section should be 10% of the portal area.

The ratio of the depth and width of the firebox is made 1: 2 or 2: 3, and its height should be 70% of its width. The depth of the firebox is made 50% of its height. If the proportions of the firebox are not observed, the fireplace can smoke.

Here are a couple of examples of dependency fireplace size from the area of the room:

Room 20 2 - portal area 0.4 2, firebox depth 35 cm, firebox height 36 cm, firebox width 45 cm, smoke collector height 63 cm, chimney section 14x27 cm.

Room 30 2 - portal area 0.63 2, firebox depth 40 cm, firebox height 36 cm, firebox width 60 cm, smoke box height 70 cm, chimney cross-section 27x27 cm.

Room 40 2 - portal area 0.77 2, firebox depth 42 cm, firebox height 36 cm, firebox width 70 cm, chimney height 80 cm, chimney section 14x27 cm.

Fireplace construction

Before starting the construction of a fireplace, you should decide on the place where it will be located and prepare all the necessary materials and tools. The place for the fireplace is chosen taking into account the fact that the chimney will pass through the ceiling and roof.

Marking a place for a fireplace

At the first stage of work, a fireplace table is marked. The fireplace table is the base of the fireplace at floor level. Its dimensions are indicated on the floor first by dots, then straight lines are drawn through the dots. It is important that the corners of the future fireplace are strictly at 90 degrees.

We mark the opening for the pipe as follows: we are looking for the center of the fireplace table and using a plumb line we project the found point onto the ceiling. We now have a point on the ceiling where the center of the pipe will be. Now from this point we measure the required distances and mark the walls of the pipe, drive nails in the corners of the future pipe.

In order for the pipe to be lined with bricks, we cut a hole for it in the roof by 12 centimeters more in each direction.

Fireplace foundation

To begin with, we cut out the floor according to the previously made markings for the fireplace table. Then we project the markings onto the underground ground. It should be borne in mind that the foundation should be 20 centimeters larger than the fireplace table in each direction. We deepen the foundation depending on the height of the building. If the building is on one floor, it will be enough to go deeper by half a meter, if into two floors, we go deeper by 0.7-1 meter.

So, we dig a hole for the foundation. You need to dig either to the planned base of the foundation, or to solid ground. We level the finished pit and tamp it.

The foundation for the fireplace does not have to be built of concrete, you can also use red brick or rubble stone. Under no circumstances should the foundation of the fireplace be tied to the foundation of the building, this can lead to damage to the fireplace foundation if the building shrinks.

Red brick foundation

We raise such a foundation to the height of a clean floor. We use cement grades 400 or 500 for masonry. Sand will serve as a filler for the mortar. The solution is prepared at the rate of one part of cement and three parts of sand.

Rubble stone foundation

We raise such a foundation to a level of two bricks below the floor level. We lay out these two rows with red brick.

Concrete foundation

We make a concrete foundation from concrete mix, which is prepared as follows: mix cement 400 or 500, sand and gravel in proportions 1: 2: 2, fill with water and mix thoroughly. Reinforcement mesh or reinforcement is also useful to us.

The concrete foundation is poured in two stages. First, pour concrete into half of the pit, after which we lay the reinforcement or reinforcing mesh... After that, fill in the rest. We level and tamp the foundation from above. Complete hardening of concrete takes about three days.

Before starting laying the fireplace, you should arrange waterproofing on the foundation. This will protect the fireplace from basement dampness.

When laying the fireplace, you should strictly follow the drawings, observing all the specified dimensions. It is also important to bandage the seams, overlapping the vertical seams by a quarter or half a brick.

For example, let's try to lay out the simplest fireplace that fits well over the entire height of the room. The materials that we need are 370 pcs. bricks, one valve measuring 23x13 centimeters, and reinforced concrete tiles for the portal and floor.

Our fireplace will have 4 rows of bricks from floor to hearth, in which case the fire will be clearly visible. In the 4th row, we lay L-shaped pins on which the fireplace grate will be mounted.

All stages of the laying of each row can be seen in the figures. Moreover, if desired, the fireplace can be made larger in height, for this you need to add the middle rows. You can also change the top of the fireplace by making a horizontal flue (rows 30a-34a). It will serve as a spark arrester.

During the laying process, the walls of the fireplace should be moistened. This is done so that the solution holds better. In order for the seams between the bricks to look the most aesthetically pleasing, they should be embroidered with special tool- jointing, which must have a convex working part. In this case, the seams will be oval.

That's all the secrets that can come in handy when laying a fireplace. It remains only to say about necessary tools required for the most comfortable work.

The correct width, height and depth of the heater ensures high efficiency. If you make it disproportionate, too large or too small, you cannot achieve the desired effect. It will be cold in the house with high consumption of solid fuel.

Combustion hole configuration

The dimensions of the firebox primarily depend on the area of the room to be heated. It must be divided by 50 to obtain the recommended value for this important structural element.

To get the maximum amount of heat at a low cost of firewood, select the optimal depth of the chamber for burning firewood. If you make the firebox shallow, you can get a smoky room. With regular heating of the house, it will become uninhabitable. The depth of the firebox must be 2/3 of the height of the fireplace.

For example, let's make a calculation for a living space of 28 sq. m.

28/50 = 0.56 sq. m. - such a firebox must be placed indoors.
The size of the fireplace is 61x92 cm. The area of the furnace opening is 0.61 · 0.92 = 0.5612 sq. m., which fully meets the conditions of calculation.
We calculate the depth of the chamber (610 2) / 3 = 406.7 mm. We round it and get that the depth of the firebox is 40 cm.

Features of calculating the chimney

In order to prevent the formation of condensation and ensure good draft, it is important to install a chimney, the outlet area of which should be 1 / 8-1 / 15 of the area of the furnace.

In our case, install a 20x26 cm chimney duct, which has an area of 0.052 sq. m, which is approximately 1/10 of the values of the furnace.

It is also important to ensure sufficient length chimney. Do not make it too high, more than 10 m. This will negatively affect the heating quality. A too low chimney will not be able to remove all combustion products, which will lead to smoke in the room. The optimal size of the chimney is 4-5 m. If you succeed great importance, install pipes with additional elbows and bends.

The carbon monoxide pipe should be located 25 cm from the main floor beams, load-bearing walls and partitions.

Foundation calculation

The foundation must have a depth of at least 500 mm. If you are installing the device in a house that is not constantly heated, then increase this value by 200 mm from the depth of seasonal soil freezing.

Separate the foundation of the heating system from the main foundation with a sand pad. The minimum distance between these structures is 100 mm.

The upper plane of the foundation should not reach the level of the finished floor by 150 mm. The base for the heater should be 5-10 cm larger from its body on all sides.

Fireplace foundation

Height adjustment

To adjust the height of the heater, special bolts are used, which are installed on its legs, or with the help of supports-stands. To set the required distance from the bottom of the firebox brick construction to the floor, lay several rows of bricks.
Basic requirements before placing the combustion chamber in height:

you need to provide a distance to the floor of 300-400 mm;
if there is a niche for firewood under the firebox, this distance may be greater;
when calculating the placement of the bottom of the combustion chamber, please note that it is necessary to take into account the construction of the floor with all its components. Think about this when planning your heating system.

Calculating the size of the fireplace

Extra options

For the installation of a safe heating system in country house consider these additional parameters:

the protrusion of the base in front of the portal, which tears off the defects of the furnace, not less than 0.5 m;
protrusion on the sides of the portal - 250-300 mm;
the pre-furnace sheet should extend 0.2-0.3 m beyond the site;
the rear wall of the firebox must have an angle of inclination of 20 °;
the slope of the rear panel starts from 1/3 of the wall;
the side panels are at an angle of 45-60 °.

Angle model calculation

To determine the size of the fireplace, which is installed in the corner of the room, you need to calculate its area. Divide this figure by 100. As a result, we get the recommended value for the heater. In our case, it is 0.28 sq. m.

The fuel chamber is made in the form of a triangle or trapezoid. This is considered the most a good option to get high productivity.

If you chose the option with a triangle-shaped bottom, calculate the width of the combustion section using the formula:

The height of the corner model should be slightly larger than the width. The depth is equal to the value obtained by dividing the width of the firebox by 1.4.

In our case, the width of the combustion chamber will be 1 m, and the height will be 1-1.2 m. The depth will be 0.7 m on both sides.

Dimensions and power of the Amur furnace

This type of heating device is very popular among the owners of country houses. With him

when choosing, consider the power of the device, which is indicated in its passport. The dimensions of the fireplace will be determined by this value, which depends on the volume to be burned.

To calculate the power, you need to know total area home, which is multiplied by the height of the ceilings. Divide the resulting figure by 20. This value will determine the minimum power of the installation. The dimensions of the fireplaces will depend on this value.

Which heating device to choose for a country house or summer cottage depends on your taste, but be sure to take into account the recommendations regarding proportions and basic spatial parameters.

Video: How to choose the optimal size of the fireplace?

Of the majority of heating appliances that are used on this moment The fireplace is the oldest. Its origin lies still from open hearths. Only after a lot of time, they began to build pipes in order to increase traction and eliminate smoke from the housing. In the old days, almost everything was made of wood, and in order to ensure safety, they began to cover the hearth with stones, so fireplaces appeared. Today, a fireplace can be seen even in apartments, but in order to build a structure, it is imperative to know the exact dimensions.

If we talk about the independent creation of a fireplace, then it is imperative to know the parameters to which it must correspond. More specifically, you need to draw up drawings of the combustion part, chimney, ordering and, of course, write down the materials that will be required in the process.

If we talk about the material, then, for example, a brick is calculated based on the order, but its exact amount cannot be determined, only an approximate one. To determine the exact amount, you need to take into account how much brick will be used for masonry and joint joints, add all this to an intermediate count.

Fireplace calculation: size advantages

Regardless of which model of the fireplace will be installed, many people perceive it only as a decoration, and, unfortunately, do not even think about why this installation has not changed after so long. But it is the fireplace that can be an excellent attribute for room ventilation. With its help, you can not only ventilate, but also dry the room. Moreover, all these actions can be performed in a very short time, many heating devices cannot do this. Fireplaces are a profitable solution for those rooms that do not have central, constant heating. For example, if you light a fireplace in a country house that is rarely used, you can quickly dry and warm up the house.

It should be noted that all these advantages are available only if all sizes were correct, compared.

It is no secret that when installing a fireplace in the house, most people worry first of all about its appearance and location in the room, and only then about such an important fact as size. In order for the fireplace to perform at full power all its functions, you need to correctly make calculations, drawings that will meet all the tasks. Only in this case the installation will work with maximum efficiency.

What should be the height of the fireplace

In order to adjust the height of the fireplace, in most cases, special-purpose bolts are used, which are installed on the legs, or special supports - stands are used. In order to adjust the required distance from the firebox of the brick installation to the floor, you need to lay several lines of bricks.

To create the desired height, you must familiarize yourself with the following requirements:

The distance to the floor should be from 300 to 400 mm, this is the best indicator;
If there is a container for storing firewood under the firebox, this distance must be increased;
In the process of calculating the location of the bottom of the firebox, take into account the design of your floor with its components.

We calculate a fireplace with an open hearth: important aspects of creation

When organizing the construction of any fireplace, one should not forget about the important recommendations of specialists. The most important thing is to follow all dimensions, since they play an important role in the characteristics of the fireplace. When you start preliminary calculations, follow all formulas and take into account possible factors and aspects.

Among the important aspects, the following can be highlighted:

The size of the insert of almost any fireplace should not be less than 25 cm, and not more than 40 cm. Such dimensions are considered optimal for domestic-type fireplaces with an average power. These varieties are the most common. If we talk about a stove for a bath, then here the width of the firebox can be slightly more than 40 cm.
If you doubt the correctness of the calculations for your fireplace design, you can check them in a simple way. The width of the firebox must necessarily match the width of your firebox door.
Please note that the difference in size will significantly reduce the heat flux, and the fuel will burn much more slowly than it should be. In any case, the wrong dimensions will reduce the use and efficiency of your fireplace.

Experts always try to pay special attention to the firebox, because its parameters are the most important indicator. The minimum size of the firebox should be 80 cm, the maximum 100 cm. Very often, when constructing a fireplace, it is impossible to achieve such an indicator, and the way out of this situation is to increase the level of the afterburner. If the size does not match, then all the combustible gases that were formed in the process will not burn.

Standard fireplace sizes (video)

The dimensions of the fireplace are a very important detail in the construction. As you can see from the article, a violation of the size compliance leads to irreversible consequences, all your work becomes in vain and most likely the structure will be dismantled. Don't neglect the rules. If you are not sure of your capabilities, it is better to turn to a professional who will certainly create an ideal and correct model of your hearth.
