The wooden house attracts with its environmental friendliness, comfort and beautiful design. Today the popularity of log cottages and summer cottages is constantly growing. Thanks to the development of technology, such a building can be equipped with the most modern life support systems. Thus, you can get a cozy home, which, thanks to the tree, will have a pleasant microclimate, and thanks to technological equipment, it will be as convenient and safe as possible for living. When designing, special attention should be paid to such an issue as heating a house from a bar. How to heat a home from this popular material, taking into account comfort and economy, we will tell you in this article.

General information about heating in log homes

Houses made of timber are distinguished by low thermal conductivity of the walls, so the heat in them is kept for a long time. In the premises of such a building, it is possible to achieve the required temperature much faster (with the same wall thickness).

To use the advantages of wood as a building material, it is necessary to establish an efficient heating system that will evenly distribute heat inside the house. In this case, it is necessary to take into account all the features of the building project. The choice and arrangement of heating is carried out taking into account such criteria as cost, complexity of work, prompt installation, simple maintenance, efficiency, and so on.

When planning heating a house from laminated veneer lumber, you can consider any types of systems that the modern equipment market offers. In this article, we'll take a look at each of them separately. Before proceeding with the choice of the type of heating in a house from a bar, you need to calculate the area of ​​\ u200b \ u200bthe heated premises. This will help determine the required heat output of the equipment.

For calculations, you need to find the product of the area per 100 watts. The resulting value will correspond to the power required to maintain the temperature of +25 ° C in the premises of a house made of timber, if it is –30 ° C outside. Accordingly, in milder climatic conditions, the consumed heat power will be lower.

When choosing heating systems for a house from a bar, in addition to their cost, it is necessary to take into account the complexity of installation and operating costs. It is necessary to analyze the efficiency of the equipment, as well as the ease of system management and room temperature control. It is worth considering the level of complexity of preventive measures and repair work, operational safety and environmental performance.

When designing a house from a bar for permanent residence, you should pay attention to heating systems in which liquid or electric current is used as a heat carrier. It is this conclusion that suggests itself after comparing the advantages and disadvantages of different options for arranging heating. The same result will be obtained when comparing the cost of heating a house using different systems.

If it is planned to build a country house from a bar for seasonal living, then networks with a liquid heat carrier turn out to be completely ineffective. For such a house, it is better to equip a fireplace or electric heating.

What is the best heating for a house from a bar: autonomous or local

The heating system option must be chosen at the design stage of the house. In this case, it is necessary to take into account its intended purpose. For a country house, where people do not live permanently, the heating requirements are not as stringent as for a cottage where a family with children constantly lives.

Autonomous heating systems operate independently of district heating networks. It is these systems that are currently the most common heating option for low-rise buildings. Individual heating is the most efficient and economical option for a private log house.

There are also local heating devices. These include various convectors, heat guns, fireplaces, infrared heaters, stoves, "stoves", etc. Each such device can provide a comfortable temperature only in a small space. Local heaters are installed in a separate room and are used most often to heat objects that are not intended for permanent residence.

Stove heating for a house from a bar: pros and cons

Stove heating is considered the most ancient option for ensuring a comfortable temperature in the house. The principle of operation of the furnace is based on obtaining thermal energy as a result of burning solid fuel (firewood, coal, briquettes, etc.). In modern houses from a bar, the stove is used quite rarely and only as a backup source of heat.

The stove heating provides warmth to the room in which the stove itself is located. The advantage of stoves is that they can operate on different types of fuel. This circumstance led to their popularity in many countries of the world.

At the same time, stove heating has its drawbacks. Some owners of private houses believe that one stove is enough to heat their homes. But if there are more than 3 rooms in a house made of timber, or, for example, two floors, then you will need to equip two or even three stoves. Such a solution will take up a lot of usable space. In addition, the owners of wooden houses should not forget that stove heating is fire hazardous.

The advantages of electric heating a house from a bar

Electric heating is an effective solution for any home. This option allows you to uninterruptedly heat the premises and precisely maintain a comfortable temperature in them. Such systems are used in many European countries.

Electric heating is versatile. Electric boilers and various heaters can be used for local and autonomous heating systems in houses from a bar.

The advantage of this option is affordable cost, ease of management, minimal maintenance, ease of installation, the ability to regulate the temperature regime by timer, compact size of equipment, low noise and no emission of combustion products. For the arrangement of electric heating in a house from a bar, you do not need a special approval of the project in the administrative authorities.

Additional benefits can be gained by equipping electrically heated floors. In this case, the air will not dry out in the premises and there will be no drafts typical for systems with water radiators. When arranging electric underfloor heating, it becomes possible to accurately and easily control the temperature regime in the room. At the same time, heating devices will not interfere with the interior design of the premises.

The disadvantage of electrically heated floors is the complexity of installation and repair, the high cost of heating, due to the high cost of electricity. Even economical systems in the cold season will consume several tens of kW per day during the day.

Is gas heating suitable for a log house?

Autonomous gas-fueled heaters in local heating systems of houses from a bar are used very rarely. This is due to the presence of open fire in such devices. There is another significant drawback of gas heaters. During fuel combustion, they burn oxygen in heated rooms.

At the same time, gas fuel is the most common energy carrier for autonomous heating systems in private houses. The main condition for such systems is the ability to connect to the central gas pipeline. Modern heating boilers that run on gas are economical, automated control system and high power. Such a unit can effectively heat a house from a bar with an area of ​​several hundred square meters. There are floor-standing and wall-mounted models of gas boilers. The latter devices can be used without arranging separate chimneys. The main disadvantage of autonomous heating with the help of such boilers is the high cost of laying a gas pipeline to the house. In the absence of such an opportunity, some developers use gas tanks or liquefied gas cylinders. Such solutions are not always economically viable.

Despite all its disadvantages, gas heating is considered the most convenient and cost-effective option for a log house. Very often, floor heating systems are used together with such boilers. In private houses with a small area, gas convectors can be installed. For the installation of heating systems on gas fuel, you will need equipment such as a gas boiler (the best option is automatic wall-mounted models with a pump), polypropylene, gas pipes and special shut-off valves.

It is important to design and professionally equip a chimney for a gas boiler. A disc with a small hole is embedded in its base. To calculate and equip the chimney structure, you will need an experienced stove-maker. It is not allowed to place the gas boiler in basements. Such equipment is located in the corridor or in the kitchen. Installing a convector allows you to achieve a more economical operation of the heating system, since it becomes possible to adjust the temperature regime in individual rooms of a house from a bar.

Other modern types of heating a house from a bar

Heating a house from a bar with convectors

Convectors powered by the mains are easy to install and easy to maintain. They are usually wall-mounted or floor-mounted. To save free space, electric convectors can be mounted directly into the floor in the area of ​​the plinth.

Such equipment quickly enough picks up the required operating temperature. Moreover, their efficiency reaches 90%.

Modern models of electric convectors are capable of operating from a network with a voltage of 150 to 242 V. Unfortunately, such a unit is capable of heating only the room of a house made of a bar in which it is located. Taking this circumstance into account, it is necessary to correctly select the power of the convector for each room. For rooms with an area of ​​about 20 m 2, an electric convector with a power of 2000 W is required.

In addition to power characteristics, other parameters of the equipment must be taken into account. The most important points include the presence of a built-in temperature controller. It can be mechanical or electronic. The most advanced convectors have special sensors that can be programmed to maintain a special temperature regime, taking into account the days of the week and the time of day.

The advantages of electric convectors include the small size of the equipment and the even distribution of heat throughout the room. The most compact models can be hidden in the skirting board.

It should also be noted that there are disadvantages in convectors operating from the mains. The disadvantages of such devices are especially manifested in houses from a bar with high ceilings. In such buildings, the heat generated by the convectors is collected under the ceiling. At the same time, the movement of warm air currents contributes to the appearance of drafts and raises dust from the floor. If an efficient ventilation system is installed in the room, then the convector loses significantly in efficiency. Part of the heated air will be removed by ventilation, so it may be somewhat cool in the room. In the presence of natural ventilation systems in a house made of timber, this effect is absent.

Liquid fuel

Oil-fired boilers are often considered as an alternative to gas-fired appliances. In the absence of the possibility of connecting to the central gas pipeline in houses from a bar, boiler equipment operating on diesel fuel can be used. Such boilers have a high cost, but there are also a number of advantages: the affordable price of diesel fuel and the possibility of arranging autonomous heating without connecting to gas mains, while maintaining the ability to automate the heating system control process. The efficiency of such equipment can be comparable to that of gas boilers. It should be borne in mind that a separate spacious boiler room is required to accommodate a liquid fuel boiler.

Air heating

Air heating systems for houses made of timber are widely used in European countries, but are not yet well known in the Russian Federation. The principle of operation of such systems is based on the movement of heated air masses in the air duct system, which is distributed throughout all rooms of the building. Thus, not only the maintenance of a comfortable temperature in the rooms is carried out, but also effective ventilation of the house from a bar occurs.

Air heating systems are characterized by high efficiency. They are distinguished by their functionality and provide an aesthetic appearance of the interiors of a house from a bar. The level of heat transfer and such equipment is higher than that of other types of heating equipment. It should be borne in mind that air ducts for supplying warm air are designed even before the construction of a house, and their repair is a rather laborious operation.

The principle of operation of air heating is that the outside air is supplied to the air heater with the help of a fan, and then it is distributed among the individual rooms of the house. Air masses that enter the system from the street can be cleaned of dust, foreign odors and various bacteria. If necessary, the air can be additionally saturated with oxygen.
To heat the outside air, liquid fuel equipment or gas heaters can be used.

The disadvantage of such systems is their high cost and bulkiness of ventilation ducts.

Air heating in a house from a bar must be designed and installed under the strict supervision of specialists, which can also be attributed to the disadvantages of such a system.

Warm floor

There are two types of warm floors - water and electric. Such systems provide additional comfort. If you have heated floors in a house made of timber, warm slippers will not be needed in winter, and small children will be able to play on the floor without the risk of catching a cold. Modern floor heating systems are easy to install, but it is better to design them even at the stage of building a house. In this case, you will not have to violate the aesthetics of the interior after the completion of the renovation.

In systems with water heating, water is used as a heat carrier, which circulates in a closed loop mounted in the floor screed. Water heating in such a system is carried out using a heating boiler.

For the arrangement of electrically heated floors, a special cable is laid in the screed.

Benefits of underfloor heating:

• heat energy is evenly distributed throughout the room;
• the air in the rooms of the house does not dry out;
• when using underfloor heating, there is no risk of drafts;
• such systems do not affect the design of the interiors of the premises;
• easy room temperature control.

Disadvantages:

• laborious installation;
• increasing the width of the screed reduces the height of the room;
• expensive repairs;
• The disadvantages of electric underfloor heating are considered to be the high cost of electricity.

The most common option for heating houses from a bar in our country is a system with a liquid heat carrier, which, as a rule, is water. It circulates in a closed loop: "heating boiler - radiators". In residential buildings, systems with forced and natural circulation of a heat carrier fluid are used. Natural circulation occurs due to the difference in density between cold and heated water. Such systems can be used in houses made of timber, the area of ​​which does not exceed 100 m2. For forced circulation of the coolant, the heating system is equipped with a special pump that creates the required pressure in the line.

The advantage of hot water heating is the high heat capacity of the water and the low cost of installation. At the same time, heating systems with natural circulation of the coolant are completely autonomous, since they can work regardless of the presence of a connection to the mains. The disadvantages of this option include the small length of the system, which can only be used to heat houses with a small area.

Heating with forced circulation of water can be used for houses from a bar of any size. But it should be borne in mind that in this case, the operation of the heating equipment will depend on the availability of a connection to the mains. In addition, the arrangement of such systems will be more complicated, since it is necessary to install additional equipment. The main disadvantage of hot water heating is the need to drain the water in the winter when the heating is turned off (water can freeze in pipes and radiators, leading to cracks). That is why such systems are rarely used to heat summer cottages, or non-freezing liquids are used instead of water as a heat carrier.

Skirting heating

A good option for a house made of timber is the arrangement of baseboard heating. In this case, heat is evenly distributed from the skirting board along the wall surfaces, which prevents condensation from forming and water does not get into the wooden walls.

In terms of its characteristics, baseboard heating resembles underfloor heating, which has recently become one of the most popular solutions for timber houses.

Combined boilers

Leading brands of private home heating equipment offer a wide range of autonomous heating boilers that can operate on several types of fuel (for example, wood, briquettes and electricity). Such models allow the owners of houses from a bar to heat the premises even during a power outage.

The cost of heating a house from a bar consists of two components - the price of equipment and the cost of installing a heating system. In order for the heating system to work economically and without interruptions in the future, higher costs have to be borne when purchasing, connecting and installing equipment.

Types of heating radiators for a house from a bar

For the installation of a water heating system for a house from a bar, in addition to boilers, it is necessary to select the most suitable pipes, connecting fittings and radiators. On the modern market for heating equipment, there is a wide selection of different types of batteries. Sectional radiators are still the most popular. For their production, materials such as cast iron, steel and aluminum alloys can be used. The most recent developments in the field of heating equipment include bimetallic radiators.

Cast iron is a traditional material for the production of radiators. Products made from it are distinguished by their high weight and high thermal inertia. Cast iron radiators attract with their reliability and long service life.

Modern cast iron batteries differ from traditional Soviet models in a more attractive design.

Aluminum radiators are lightweight, but they do not tolerate pressure drops in the system, therefore they are considered insufficiently reliable. Bimetallic batteries are made from steel and aluminum, so they combine the best characteristics of these materials. The aluminum body can significantly reduce the weight of the structure, and the steel pipes transfer heat well and are reliably protected from corrosion. The presence of a large selection of different models of radiators creates certain difficulties for buyers when choosing products for arranging heating in a house from a bar. In order not to make mistakes, it is worthwhile at the heating design stage to consult with experienced specialists who are well familiar with modern heating equipment. Special attention should be paid to the qualified installation of such systems.

Installation of a heating system in a house from a bar

For laying pipes for heating systems in houses from a bar, as a rule, two methods are used:

1. External wiring involves laying communications along walls, above the floor or under the ceiling. This is the simplest installation option, which, however, can disrupt the stylish interior design.
2. Hidden laying is carried out inside building structures (walls, interfloor floors, etc.).

For the distribution of heating in a house from a bar, plastic, copper or steel pipes are used:

• Plastic pipes- the most inexpensive and practical option, which is chosen by many developers.
• Copper communications are reliable, but they are much more expensive. Such pipes should be used for external wiring, as they have a respectable appearance.
• Steel tubes they are rarely used for laying heating in houses from a bar. This is due to their high weight and installation complexity.

Shrinkage is common in timber buildings. Since it is impossible to avoid it, it is imperative to take it into account when installing heating pipelines. Failure to do so could damage the system, leading to serious trouble. To avoid such problems, you need to consider the following points:

1. The distribution of heat throughout the house from a bar and a stable temperature regime is an important condition for the uniform shrinkage of a wooden building. To ensure the fulfillment of such conditions, you need to competently approach the choice of a heating system.
2. In a house intended for permanent residence, you should not equip traditional stoves. Such structures contribute to increased heating of individual walls, which can lead to the appearance of cracks in their structure. The ideal option in this regard is underfloor heating.
3. To prevent humidification of the walls made of timber, experts recommend protecting heating and water pipes with heat-insulating material.
4. During the installation of the heating system, the integrity of the supporting elements must not be violated. Sliding fasteners and expansion joints should be used to fasten the risers. With rigid installation, the shrinkage of the house from the timber can be torn from the fasteners.

To create comfort and in order to ensure the efficiency of the heating system, it is necessary to insulate well the structures of the walls, floor and roof. In addition, it is necessary to take care of the tightness of window and door structures. Only if all of the above rules are observed will heating a house from a bar be reliable and efficient.

TO GET A CONSULTATION

Living in your own home has a number of nuances. And one of them is associated with the arrival of General Moroz, when you have to independently solve problems with heating living quarters. How can a house be heated from a bar? There are many options, and some of them are presented in this post.

A necessary note about heating a house from a bar

In recent years, when building houses from a bar, many developers prefer to use a material of natural moisture. This imposes some restrictions on the use of heating systems in such buildings, because the blockhouse must dry evenly. Otherwise, impressive cracks and other troubles may appear in the walls of the timber, the consequences of which are not so easy to fix. In the early years, even scorching sun rays hitting the walls can lead to disastrous consequences, what can we say about heating ?!

In the first year, you should not think about any heating of the building - at this time, there is a significant shrinkage of the material in natural conditions. Subsequently, the house is heated from a bar at a temperature not exceeding 12 degrees Celsius. The constancy of such a temperature, coupled with active ventilation of the premises and control of the humidity of the timber, will allow it to dry under optimal conditions - this approach minimizes the risks of cracking. The moisture content in the material should change slowly: during the winter period it is better if it reaches the threshold of 18%, not lower. After that, you can gradually increase the temperature in the room, but no more than 2-3 degrees per week. When the humidity reaches 15%, the air temperature can be raised to 25 degrees - for the first heating season this will be the maximum value.

Current types of heating

Before turning on the heating system, it is necessary to insulate the floor, walls and roof of the house from a bar well. Otherwise, you will have to "heat the street", which in fact means a waste of funds. There are several solutions for heating, but only a few are actively used in our country. The first three types, shown in the table below, are optimal for use in a home for permanent residence. Stove heating is gradually losing its position and now it is most often used for summer cottages.

The most popular types of heating for houses from a bar or OCB

a brief description of	Advantages and disadvantages
Water	Water is used as a heat carrier, circulating in a closed loop "boiler-heating radiators-boiler". There are two options for such heating for a house from a bar: with natural or forced circulation of water. The first option is suitable for small buildings up to 100 sq. m. The movement of the coolant in this case is due to the difference in the mass of hot and warm water. Systems with forced circulation of the coolant are equipped with an electric circulation pump, due to which the required water pressure is provided.	For systems with natural circulation of the heat carrier: + independence from power supply; - small radius of action For systems with forced circulation: + you can heat the house from a bar of any size; - complex installation, due, among other things, to the installation of additional equipment
Air	The heat carrier is air heated by the air heater. Heat exchange is carried out in a special heat exchanger, where air is forced from the premises. Heated air is distributed through ducts throughout the house	+ high efficiency; + controlled change in air temperature both inside the house and in individual rooms; - dependence on power supply; - complex installation; - this type of heating should initially be taken into account in the project of a house from a bar
Underfloor heating system	Distinguish between systems with water and electric heating. In the first case, the coolant (water) circulates in a closed loop, which is a tube embedded in the floor screed. The heating medium is heated in the boiler. In the second case, instead of tubes, an electric heating cable is used.	+ even distribution of heat over the area of ​​a separate room; + the air does not dry out; + absence of drafts caused by the operation of the heating system; + does not affect the design of the premises; + simple regulation of air temperature; - complex installation; - the height of the premises is hidden; - costly repairs For electrically heated systems: - high cost of electricity
Stove	The traditional version of local heating, implying the construction (installation) of a massive stove or fireplace	+ can become a spectacular element of interior design; - with the help of one stove it is impossible to heat the whole house (except for a small summer cottage); - low efficiency; - the oven takes up a lot of space; - requires periodic maintenance; - is often the cause of fire

Instead of conclusions

Whichever heating system you choose for a wooden house, first learn how to deal with heat loss. Remember that a significant part of the heat is lost through non-insulated walls and roofs, log house windows. And be sure to keep in mind that how you heat a building in the first years of operation can have a serious impact on its durability.

In this article, we will tell you about the most popular and demanded heating systems in a private house from a bar. You will learn what you need to pay attention to when planning home heating, how to choose the best system option for your home.

What are the pros and cons of water, air, gas, electric and stove heating of wooden houses.

Wood has high energy-saving characteristics, but the organization of heating a house from a bar is a responsible matter if you plan to use such housing as a permanent place of residence.

Where to start choosing

Solid fuel boilers work mainly on wood and coal. Nowadays, they are used less often, but they are not devoid of their advantages.

Heating radiators in a wooden house made of aluminum light in weight, but less durable, do not tolerate pressure drops. Biometal radiators combine the advantages of aluminum and steel. Lightweight aluminum body and heat transfer medium made of steel pipes, which do not corrode and thus have a long service life.

Local heating houses from a bar are made using heat guns, convectors, fireplaces, air heaters, stoves, stoves. The disadvantage of this type of heating is that these devices can only heat a small room.

To organize an autonomous system heating a house from a bar requires a centralized boiler and pipes. This installation must be stationary and warm up the room completely. Today it is the most popular type of heating for low-rise buildings. The effectiveness of this type of heating is achieved with the help of an individual approach to the creation of heating systems projects for each individual home.

Gas heaters not very often used on local systems. These designs provide for the presence of an open hearth. In addition, gas burners absorb large quantities of oxygen.

In autonomous heating systems gas log houses are very popular. Heating boilers in a modern wooden house are so improved that they practically do not need to be monitored. The system is fully automated, boilers are economical, they immediately heat large areas.

Steam heating of a private house from a bar

Provides for the continuous movement of water in a circle. The system consists of an expansion tank, a boiler, polypropylene pipes. For better water circulation, a pump is cut into the system. How fluid is used as a heat carrier non-freeze.

Advantages

• It is possible to heat the whole house, even with a large area.
• The boiler is installed in a specially designated place.
• There is a temperature control function.
• High efficiency and economy.
• Solid fuels can be used.
• Installation of a double-circuit boiler for heating water and heating the room.
• One fuel fill is enough for a long time.

disadvantages

• The complexity of installation and high cost.
• The high cost of boiler equipment and its maintenance.
• You need to look for a separate room for the boiler.
• Depends on electricity (circulation pump).

Heating a house from a bar with an air system

Here, the coolant is air, which enters the system after heating. This type of heating is suitable for regions with mild climates.

pros

Minuses

• It must be installed during the construction phase of the house. Pipes carrying air are installed in recesses in walls, under the ceiling or in false walls.
• The system needs constant maintenance, which is difficult with this installation method.

Water underfloor heating

The option in a wooden house also has its advantages and disadvantages. The heated water flows through pipes made of metal polymer.

Any type of flooring can be laid on top of the system. If the system fails, the floor will remain warm for several days. The disadvantage of such floors is the complexity of installation, you must first make engineering calculations.

The screed is made at a level of 8 cm, which in turn steals space. The optimum temperature for heating water should be at 40 ° C.

1. Centralized. Hot water is supplied from a common boiler room. In cottage settlements, the option is rare;
2. Gas. The high costs of connecting to the main gas pipeline are offset by the low cost of equipment and monthly expenses. The only limitation is that gas is not supplied to all villages;

1. Autonomous gas. The tank (gasholder) is buried at the site, regularly filled with liquefied gas. Installation and maintenance costs increase, but the owner gets an independent gas supply system;
2. Electrical. Heating a house from a bar with electricity leads to high costs, but does not require a separate room. Electric boilers are often used as a backup or additional circuit. Complete with boilers (or instead of them), autonomous heaters are connected in the form of radiators, heat guns, curtains;

1. Liquid fuel. For work, diesel fuel, fuel oil or waste oil is used. Modern liquid fuel boilers operate autonomously, in terms of the number of settings and reliability they are not inferior to gas equipment;
2. Solid fuel. A wide range of boilers - from models with wood burning with manual loading to fully automatic systems with a bunker for fuel, which operate on one load from 12 hours to several days;
3. Solar collectors. Collect and convert solar energy into heat. Even the winter level of illumination is enough for heating. The equipment is highly dependent on the weather, therefore it is used as an additional one.

In most cases, a combined heating system for a house from a bar is installed - equipment for operating on different energy sources:

• Gas (diesel, solid fuel boiler) + electricity. A heating element is built into the tank for heating water or a separate electric boiler is used. Electrical equipment starts up when the coolant temperature drops below the set value;
• Gas + diesel (mining, fuel oil), gas + pellets (firewood, coal, pressed sawdust). Systems with two burners switch to another type of fuel automatically or manually. Such devices are used to increase the reliability of the system or when installing equipment in houses with the prospect of connecting to the mains and using gas heating of a wooden house.

Differences between heating a house made of laminated veneer lumber, ordinary timber and brick (blocks)

The correct design of the heating system of a wooden house takes into account changes in the characteristics of the walls. The deterioration of the thermal properties in houses made of logs and ordinary timber is especially noticeable. Indicators of walls made of laminated veneer lumber and brick do not depend on age.

Heating a house from a bar

In buildings made of ordinary timber, through cracks and gaps between the crowns appear after 1-2 years. Heating equipment has to be chosen with a margin, additionally insulate the walls, and regularly repair cracks.

Heating a house from laminated veneer lumber

The crowns retain their shape: glued lamellas keep each other from deformation, the structure behaves as a whole. The appearance of through cracks is excluded. The crowns are connected by a thorn-groove system ("German comb"), the space is protected from cold air. As a result, over time, heat loss through the walls does not change - you can use standard calculations for the selection of equipment.

Heating a brick cottage

Walls made of various types of bricks have one thing in common - it takes more time to warm up the wall and cool it down. Due to such a delayed reaction to heating, it is advisable to use weather-dependent automation for more accurate temperature control. Wooden houses warm up faster.

Important: when warming up a house from low or negative temperatures, it is worth adhering to the recommended heating rate - if the temperature changes too much, the wood may crack. Therefore, the wooden house warms up smoothly, without turning on the equipment at full power.

Heating devices

The list of heating devices for a private house is much more diverse than residents of city apartments are used to using:

1. Radiators. Classic heating option, suitable for heating all standard rooms. Models are made in the form of sectional, flat and tubular structures;
2. Warm skirting board. Compact radiator with plinth-style housing. Installed around the perimeter, creates a stream of warm air. The model is suitable for rooms with panoramic glazing. For example, in the specification of the F-274 project, it is a warm skirting board that is proposed for heating glass walls. In some cases, a warm skirting board is combined with standard radiators or underfloor heating;
3. Thermal curtains. The devices are built into the floor, mounted above a window or doorway. The technique creates a directed flow, cuts off atmospheric air, reduces heating costs with frequent opening, is mounted in wide openings (double entrance doors, garage doors), panoramic glazing. The equipment works constantly or reacts to sensors;
4. Warm floor. Piping (when connecting hot water heating) or heating cable (electric heating) in the bathrooms, on the ground floor, in the pool. Underfloor heating is used specifically for heating the floor surface. Depending on the heat calculation, the warm floor is used independently or in combination with other heat sources;
5. Convectors. Radiators built into the floor are usually equipped with a fan for more efficient heat dissipation. They are used under panoramic windows or balcony doors.

The devices can belong to a single heating system or operate from different sources. For example, radiators and underfloor heating are usually connected to the main (water) mains, curtains and heat guns use electricity directly. In addition, a fireplace can be installed in private houses - a live flame also becomes an additional source of heat.

Design and installation of heating of a country house

The design begins with the determination of the required boiler output. For this, the heat loss of the house is calculated, which takes into account the heat loss through all the enclosing structures (walls, floors, roof, windows), the location of the premises relative to the cardinal points, the ventilation systems used, the climatic zone of construction. On average, to calculate the required heating power, they are guided by 1.2 kW of energy for every 10 m² of heated area, but for each object, the calculations are carried out individually.

The main steps in the selection of equipment and design:

1. We draw a detailed plan. The diagram shows the location of windows, doors, balconies, toilets, bathrooms;
2. We clarify the available coolants and the needs of the owners. Each boiler can play the role of the main, additional and backup heating source, be used for hot water supply, operate on one or several circuits;
3. We develop manifolds for dividing the flow for underfloor heating, supplying coolant to radiators, maintaining the desired temperature in the greenhouse, swimming pool, sauna;
4. We select radiators by power and appearance, boiler model, pipeline material;
5. If necessary, we install additional equipment - a boiler for hot water supply, a second boiler for cascade connection, automatic control systems.

Weather-compensated automation: intelligent heating control system

The equipment can be operated manually, but in most turnkey projects weather-dependent automation is installed. The sensors take into account the temperature in the rooms, but react to changes outside, that is, they adjust the parameters of the boiler operation even before the temperature in the rooms changes.

The smart system can be configured to any modes:

• taking into account working hours (when no one is at home, the temperature drops);
• divided into night and day hours;
• for different temperatures for underfloor heating circuits, saunas, swimming pools, living quarters;
• make an automatic account of the heat capacity of the walls;
• install a GSM module, monitor and control heating remotely.

The equipment quickly and accurately reacts to changes, maintains the same temperature in automatic mode.

Heating price for wooden houses

Heating costs are divided into 2 parts:

1. Connection costs, purchase of equipment and installation;
2. Monthly fee.

Typically, with large one-time network launch costs, the monthly payments are reduced. For example, paying duties, connecting to the gas main and installing a boiler are more expensive than buying an electric heater, but the monthly heating fee is several times less.

When making calculations without the help of a specialist, the owners forget about important elements and receive incorrect numbers. Our engineers have prepared a quick guide for choosing a heating system with basic equipment prices.

In the GOOD WOOD catalog, look at projects of houses from a bar with "turnkey" heating. Any other equipment can be used. Order more complex automation, add backup circuits, specify the price of heating installation for different systems - the engineer will quickly calculate the cost and show the difference between the systems.

We have calculated the monthly heating bills for most of the finished projects. Make an estimate of costs even before construction, estimate price changes when using different heat carriers - the difference is shown very clearly in the calculator.

The heart of any wooden residential building is the heating system. The most important task in building a house is to design and assemble this heart. If you have patience and you have golden hands, then the installation of heating in a wooden house can be done independently. To do this, it is enough to familiarize yourself with the technical literature and watch a thematic video.

Before installing the heating of your wooden house, you need to choose the type of heating that will be appropriate for your home and will meet your needs and requirements. The task of installing heat in a home requires a lengthy calculation process and careful planning. A mistake in conducting heat in a home can be costly. This is the defrosting of the entire system and burst pipes, with a water heating system. With electrical, this is at least a short circuit.
With an air system, in general, the complexity of dismantling, after installation, does not make it possible to fix something.

The choice of the type of heating of a private house largely depends on what kind of access to energy is available. The type of energy carrier when heating a private wooden house can be:

1. Hard fuels (coal, firewood).
2. Electricity.
3. Liquid fuel (diesel, kerosene)

The choice of the heart of the thermal system - the boiler - depends on which source will be involved.

Choosing a boiler

If the source is gas, then it is best to choose an automatic wall-mounted gas boiler. Such a generator is equipped with a pump and protection. If a chimney is not provided, then you need to opt for a boiler with a closed combustion chamber. And to remove air in such a boiler, you can use a coaxial pipe. This will save money on the installation of the pipe.

Wall-mounted boilers already have full automation, but with a water volume of more than 100 liters, install an additional expansion tank, even if there is a built-in one. It will make it possible to compensate for the expansion of the water during heating. Otherwise, the pressure in the boiler will greatly increase with increasing temperature, and the automation will often turn off.

If the choice fell on an electric boiler, then it is best to choose a full automatic machine, with a built-in pump and an expansion tank. This option will be more convenient in installation and will avoid many mistakes.

Be sure to use a special apparatus for stabilizing electricity for such a boiler.

If the fuel is of a tough nature, then such a boiler can be installed by yourself, only knowing how to weld. And they are able to weld heating pipes with their own hands. The outlet temperature of this type of boiler can reach 100 degrees and it will be difficult to install any pipes other than iron pipes without the use of professionals.

It is also possible to use plastic pipes in a system with a boiler running on hard fuel, but a special decoupling is required. It can only be performed by highly professional heating technicians.

When the boiler is selected, you need to choose the right pipes and radiators. The material used for pipes today is different. But when installing with your own hands, it is best to use plastic. It is easy to assemble. The quality of metal pipes has deteriorated significantly today. So from the proposed option, choose metal-plastic or polypropylene.

The material has been selected, it remains to draw a diagram and choose a project for your home. The project will depend on the type of heating you choose.

Radiators are chosen depending on what kind of heat transfer you want to get and which are suitable for your interior. The more sections the radiators have, the warmer it will be in the house. The calculation to see each other is 1 section by 1, 5 square meters.

The appearance of the radiators should not spoil the overall appearance. You will make the right choice by watching the video:

The calculation of materials is carried out after drawing up a detailed diagram of the heating system of your home.

For a wooden house, radiators with a bottom entry are usually taken. This is due to the fact that it is difficult to hide pipes in the wall of such a house. They are hidden under floors between floors.

Installation of heating in a wooden house

Gas heating is the most affordable for 80% of private households today. Gas is cheaper in Russia than in the rest of the world. And this makes it possible for the Russians to use such heating even with a large living area. Gas equipment is quite simple to install, but it requires a specialist approach.

The first thing to do is to draw up a scheme according to which the amount of material will be calculated and the entire system will be mounted. It is very important to draw up a project for the heating system of the entire building in general. The project will include a heating scheme for a specific house, installation of the system, a list of required materials, cost calculation and budgeting.

Heating schemes

The most popular scheme is the heating scheme by means of water. Water heating is based on the circulation of water in the system from pipes. The water is heated in the boiler and enters the pipes, from which it enters the radiators or other types of heating devices. Heat transfer takes place there. Then the water is returned to the boiler again.

The type of the chosen scheme will depend on how the water moves through the pipes naturally or artificially. The scheme can be drawn up on the basis of the number of heating circuits, two-pipe or one-pipe.

If the circulation process occurs naturally, that is, the water moves under the influence of its chemical functions (expansion during heating), then the circuit will be one-pipe.

If water moves in the system under the influence of a pump (artificially), then the system may already have a two-pipe scheme.

When using a one-pipe system, it is difficult to regulate the temperature throughout the house. It will be different. The further the radiator is from the source, the lower the temperature in it. The two-pipe system makes it possible to avoid this.

Installation of a one-pipe heating system

Fig. 1 Diagram of a one-pipe system

For example, imagine two schemes for installing a one-pipe heating system for two-story wooden houses. Using them, you can simply mount such a system with your own hands.

The disadvantage of installing such a system is that the lower radiators will heat up a little less. And a wooden house on different floors will have different temperatures. But on the other hand, subject to the exact scheme, it is easy to assemble it with your own hands. And another advantage of such an installation is the small amount of materials involved in the design. And in order to equalize the temperature, you just need to increase the number of sections on the radiators installed at the end of the system. For faster circulation, a circulation pump can be installed at the cold water inlet.

Fig. 2 Diagram of a one-pipe system

It is worth noting that schemes with natural circulation are possible if it is possible to install the boiler below the installation level of the radiators. Otherwise, water simply will not circulate in the pipes. During installation, it is necessary to observe the natural angle of inclination from hot water towards the radiators and vice versa, from cooled radiators to the boiler. The expansion tank must be installed in such a scheme. When installing a pump in such a system, its efficiency increases significantly and will make it possible to install the boiler at any level. If the boiler already has a pump in its configuration, then the issue of installing separate equipment is no longer raised.

The system shown in Figure 2 (horizontal arrangement of pairs of radiators) implies the use of such a pump. To maintain an even temperature throughout the system.

The difference between the two schemes lies in the junction with a shut-off valve.

Installation of a two-pipe heating system

Fig. 3 Diagram of a two-pipe system

Figures 3 and 4 show diagrams of two-pipe heating systems. Figure 3 shows a diagram with natural water circulation in the upper circuit. Radiators in this case have the same heating temperature. But the cost of material for such a system is higher than one-pipe. For each radiator in such a system, shut-off valves are used, which will allow you to control the temperature in each of them separately.

In Figure 4 we see exactly the same system as in Figure 3. But with lower wiring.

Fig. 4 Diagram of a two-pipe system

This is a good option for those planning to install a boiler in the basement and pipes are an additional source of heat. This scheme is more popular for gas heating of two-story wooden houses with your own hands. Wooden houses are distinguished by the fact that radiators can be attached to the walls directly at once or by first nipping two bars.

These schemes are also suitable for boilers with hard fuels. The only thing that needs to be changed is the pipe material.

Electric heating

If gas is not available, electricity can be used. There are many options for a wooden house. This is a "warm floor" system, which is sold ready-made or made independently.

It is not very convenient for houses with wooden floors (see) because its installation requires a concrete screed. But if you make a warm floor from a water electric boiler, then this is a very real project.

This system has its advantages. This is a silent operation, the accuracy of the temperature regime in the room.

Metal-plastic pipes with a diameter of 16 - 20 cm are taken. They are laid on a heat-insulating layer. The stacking pattern is usually spiral, as shown in the diagram, or combined. From the base of the collector pipe, which is connected to the boiler, see 10 cm from the walls. The second circuit has a distance of 40 cm from the first. This is done in order to then put the pipe back here. So the laying step will be 20 cm.

It is necessary to fasten the pipes to each other in a straight section after 1 m, more often at the bends.

After fastening, the reliability of the system is checked. Simply put, they fill the pipes with water and see if there is a leak. Then a second wooden formwork is made in the wooden house and the floor is laid on top.

The peculiarity of such a system in a wooden house is that the pipes are obtained as between two formwork, lower and upper. Thermal insulation does not allow the heat to escape downward and, as it rises upward, it heats the floor and the room.

Such a system can be used in homes where there is access to electricity or no gas. Solid fuel boilers still exist today. Their installation is difficult, and requires the skill of not only a heating engineer, but also a welder. The design of such systems, in principle, is not much different from a single-line heating scheme of natural circulation. Only the pipes will come from either the stove or the hard fuel boiler.

If the boiler has a more modern configuration, then the installation of such a system is the same as in Figures 1 and 2

When installing this type of heating, you need to use metal pipes.
