What are the best heating radiators to install? How to choose heating radiators: types and characteristics

A radiator is a necessary part of the heating mechanism of a private home or apartment. He is responsible for making the room comfortable and warm. Therefore, when choosing it, it is necessary to take into account not only the cost and external design, but also the technical characteristics of a particular product. After all, if the characteristics declared by the creator of the radiator are not the same in reality, then rapid wear and tear of the device and its breakdown are simply inevitable.

Main characteristics

In a private house, unlike high-rise buildings, an autonomous heating mechanism is installed, that is, a system that does not depend in any way on a conventional boiler room. For this reason, the coolant temperature, as well as the network pressure, will be completely different.

When you choose heating batteries that will be installed in a private home, a number of factors should be taken into account:

• In buildings of this type, the pressure on the coolant, tanks and radiator pipes will be significantly less. In fact, radiator batteries will not experience such loads, which is why you can choose any model, even with thin walls.
• In buildings of this type, the length of pipes from the heat source to the radiator is short when compared with multi-story buildings. For this reason, heat losses are practically zero, and the coolant will heat up more strongly. That is, in a private home you should install models that will withstand such temperatures.
• You need quite a bit of liquid to fill such a heating system. If desired, you can add ethyl alcohol and antifreeze to it. This way you can make protection for radiators and pipes if the boiler does not turn on for a long time.
• Even the slightest possibility of so-called water hammer occurrence is excluded. True, in private houses a problem may arise, expressed in the freezing of water in the pipes. This will cause the batteries to simply burst if a person forgot to drain the water from there before leaving.

When choosing heating radiators for a private home, you should start from the main parameter - the area that you are going to heat. In the same cottages, the space requiring heating will be large, and the energy costs will be the same. It is best to install batteries that will allow for high-quality heating with a minimum of heat costs.

Kinds

It should be said that heating batteries are various types. And here we're talking about not so much about their shape and size, but about the material from which they are made. It's no secret to anyone that various metals have different heat transfer rates, which is why the coefficient useful action batteries may vary significantly.

If we talk specifically about the types, then there are radiators:

• made of cast iron;
• made of aluminum;
• bimetallic;
• vacuum;
• of steel;
• quartz.

Now let's talk about each type in more detail.

Cast iron

The models under consideration have been installed in our homes for more than a hundred years. They are still in great demand today due to the fact that they provide high-quality heating of rooms. They were also one of the most popular in the USSR.

If we talk about their advantages, we should name:

• long operational period;
• excellent thermal efficiency;
• high durability as batteries can easily withstand high pressure inside and easily tolerate mechanical stress;
• work even with poor quality coolant;
• are resistant to corrosion.

At the same time, cast iron models also have a number of disadvantages:

• large sizes, which significantly complicates transportation, maintenance and installation;
• low thermal conductivity due to the massiveness of the metal and the fact that its surface is porous;
• batteries require systematic and constant care - painting and maintenance;
• the walls must have good fastenings for their installation;
• occupy a large area.

In addition, cast iron models do not have a very attractive appearance, which almost always does not distinguish them from the interior in the best way. Therefore, it is often necessary to put additional decorations on such radiators.

Steel

If we talk about this type of radiators, they are divided into three categories:

• panel;
• from sections;
• from pipes

Steel panel batteries are also called convectors, because heat is supplied precisely through the convection process. They usually have a rectangular shape formed by two welded panels. The coolant moves between them through special channels. Such a radiator is light in weight and small in size, which makes it possible to heat up in a short time and maintain a good temperature.

If we talk about disadvantages, the main problem is poor resistance to mechanical damage and not very good performance pressure. In addition, such models are very susceptible to corrosion.

The characteristics of steel section batteries are somewhat similar to cast iron ones, although they have a number of serious differences:

• the pressure inside here is at 16 atmospheres;
• due to the presence of welded joints, radiators have increased strength;
• long operational period - up to 50 years.

This type of radiator is not very common, because its significant disadvantage is its high cost. Tubular steel batteries are similar in functionality to sectional and panel radiators, but their price will be even higher. The main reason This is because they have a rather pleasant appearance, which allows you to find a model for the interior. And such batteries are extremely convenient for drying things, which will be important for families with small children.

Aluminum

Aluminum belongs to the category of metals that conduct heat well. For this reason, such radiators can provide complete heating of almost any room.

Their advantages are:

• excellent thermal performance characteristics;
• small sizes;
• good working pressure, which ranges from 12-18 atmospheres;
• small mass.

The coolant in radiators of this type circulates very well, which allows for excellent heat transfer. Such circulation is possible here due to the presence of free inter-collector tubes. Such models are represented quite widely on the market.

The cost of aluminum batteries will depend on the manufacturer, but in general, it is quite affordable due to the low price of aluminum itself. In addition, such models have an attractive appearance, which makes it possible to consider them not only as a heating device, but also as part of the interior of the room. Thanks to its strict and neat geometric shapes, such a battery can easily fit into any interior.

But aluminum models also have their disadvantages:

• they are extremely sensitive to the quality of the coolant, which is why they require the installation of water filtration;
• very susceptible to serious changes in pressure, so it is necessary to constantly monitor its level;
• They resist corrosion rather poorly, even despite the presence of a polymer-based protective coating;
• have a short service life - no more than 15 years.

In addition, the positive impact of such batteries is not always an advantage. Good performance of such a battery drives warm air upward, which accumulates near the ceiling, which can cause a sharp temperature change. Therefore, before buying such batteries, you should calculate the amount of heat needed for the room.

Aluminum batteries are divided into three categories, which will differ from each other in design and capabilities:

• Sectional arranged. Their device makes it possible to replace plates that are broken.
• Whole. Have robust construction and are characterized by plasticity.
• Combined. They combine the best of the two categories mentioned above. They are considered one of the best solutions for owners of their own homes. If you fully comply with the operating conditions, then such radiators can last 10-15 years and will really effectively heat the house when it’s cold outside.

Bimetallic

As a rule, the internal part of such radiators is made of steel or copper, which allows them to be Good work and enhances security. A outer side usually equipped with aluminum fins. Today, bimetallic batteries are considered the best solution in this domain. According to manufacturers, their batteries can last about 40 years. At the same time, they are more expensive, but still their characteristics have provided them with an excellent position in the market. It is advisable to buy such solutions if price is not the main issue. But they will definitely recoup the money invested and will work for quite a long time.

Vacuum

Recently it has started to gain popularity vacuum type batteries If we compare them with other types, they have whole line benefits. For example, they require a smaller amount of coolant, which will come into contact through the wall with a special solution based on lithium and boron, which has a boiling point of +35 degrees. Also, such radiators have excellent safety characteristics.

If we name other advantages, it should be noted:

• reduction of the coolant level for the functioning of the mechanism by 80 percent;
• reducing the use of coolant from a centralized heat supply mechanism by three times;
• if used induction boilers, then you can save up to 40 percent of electrical energy;
• Installing such batteries is quite simple, even on your own;
• There is absolutely no corrosion or air pockets in the radiators;
• no need to use powerful circulation pump unit due to low local resistance;
• high thermal efficiency.

Quartz

Heating devices made of quartz are new in this segment. This type of battery cannot be called high-tech, because it is an extremely simple option. Using batteries of this type, you can make an effective, reliable and economical heating mechanism in a room that will maintain heat in the winter. A quartz radiator will fit into any home interior.

Its design is simple and consists of a monolithic plate, inside of which a heating element made of chromium-nickel alloy is built. The slab is made from a special solution based on quartz sand. The use of such sand is not accidental, because it can give off heat that it previously accumulated for quite a long time. Even if such a radiator is disconnected from the heating network, it will remain warm for a long time, which will significantly reduce electricity consumption.

If we talk about the advantages of this type of battery, we should name:

• Economical. Low electrical energy consumption is the main advantage heating devices from quartz, because other solutions consume significantly large quantity electrical energy and their other advantages simply disappear, because the price of electricity is quite high.
• Significant heat capacity. A quartz slab has quite serious thermal inertia. It takes a long time to warm up and cools down slowly, as mentioned above.
• Durability. In this case, the heating element does not come into contact with environment, which prevents it from oxidizing and significantly increases its service life.
• You can connect a thermostat, which allows you to obtain automatic control of the heating system.
• Quite low cost when compared with water heaters electric type or other heating devices.

• Fire safety. The temperature of such a battery will not exceed 95 degrees, which is why the ignition of materials located next to the heater is completely excluded. This allows the device to be mounted on almost any surface, including wood, plastic and drywall.
• Electrical safety. Such a battery does not create serious loads on the electrical network and can operate uninterruptedly throughout almost the entire season.
• Easy to install. The quartz battery is attached to the wall using brackets.
• They do not require maintenance and do not require serious care. The only thing you need to do with such a battery is to wipe off the dust.

Popular manufacturers and reviews

In the segment of cast iron models, the most famous manufacturers are the Chinese companies Tokio and Konner. A good domestic model of such batteries would be the MS-140.

If we talk about steel panel solutions, the products of Korado, Buderus and Lidea are considered the highest quality. But tubular steel solutions are usually produced by foreign companies. Among them, the products of Zehnder, Arbonia and Delonghi should be highlighted.

Aluminum batteries are produced by both foreign and domestic companies. Among them are such well-known manufacturers as Global, Ferroli and Rifar.

Bimetallic models are produced by both foreign and domestic companies. If we talk about domestic ones, then we should name the brand “Teplopribor,” and if we talk about foreign ones, then these are products of the brands Polywarm, Sira, Royal Thermo Vittoria and the German company Kermi. When choosing ceramic batteries It is worth paying attention to the products of the Tepleko brand.

Now let's talk about users' experience of using different types of batteries and their reviews. This is logical, because manufacturers often say one thing, but in practice we get something completely different. If we talk about cast iron radiators, users note that even beautiful solutions They are not easy to install and they are quite heavy. In addition, they often require the installation of additional brackets.

Let's talk about aluminum radiators in a little more detail after reading reviews from users of batteries from various brands. If we talk about aluminum batteries Sira company, users note that they heat well and have an excellent appearance. Users also note good heat transfer models. But many are not very happy with the considerable cost of solutions from this company. Users also praise such batteries from Global and note that they heat well in combination with the boiler and have an excellent appearance. The same applies to solutions from Rifar.

Users also do not ignore bimetallic batteries and generally speak very flatteringly about them. For example, Rifar batteries look great in various interiors, are quite durable and can withstand a lot of pressure, as well as high temperature coolant. In general, it is impossible to create any clear rating of radiators, because they all have a number of their positive and negative sides. One thing can be clearly noted - in any case, it is necessary to individually determine which batteries in a particular private building will be the best solution.

Which ones are better to choose?

If you want to choose economical option For a country wooden private building, it is best to install high-quality aluminum radiators. Such solutions have everything you need: modern design, lightness, affordable price, and their negative sides are not so serious in the conditions of an autonomous heating mechanism in a private house.

If money is not such a serious issue, then it will great solution installation of sectional bimetallic batteries, especially if we are talking about a copper-aluminum combination. And if there are small children in the house, then in order to protect them and the rest of the household, you can opt for convection options, equipped with certain protection options. If you need to hide radiators, you can use floor convection solutions.

If the house has a stove with a water circuit, the simplest solid fuel boiler, or your house is equipped with gas heating, then you can use time-tested cast iron batteries. Despite the fact that their choice entails difficulties with installation and weight, at the same time they make it possible to significantly smooth out temperature fluctuations and store heat for a longer time. And even now you can easily choose options with a nice design, if you can afford them.

Installation Rules

Radiator heating in own home– the key to comfort and coziness in autumn and winter. It is good when such a mechanism has already been connected to a centralized heating mechanism. If there is no such thing, then there is a need to use autonomous heating. If we are talking about installing the heating system with your own hands correctly, then it should be said that the most important element there will be a choice of options for connecting radiators in a house of your own construction.

A number of people do not even suspect that this plays a very significant role in the heat transfer of the heating device, the circulation of the coolant inside it and the speed of movement of hot water. The above as a whole will have a significant impact on the efficiency of the entire mechanism.

The first thing you need to figure out is the pipe layout. This can be called an important point, because residents of their own houses at the stage of their construction can rarely clearly and correctly calculate the costs that will be made for the formation of a heating system, so they have to save on various types of materials. Typically, the method of connecting pipes can be either single or double pipe. The first option is economical, in which a pipe is drawn from the heating boiler along the floor, going through all the walls and rooms and which returns to the boiler. Radiators should be installed on top of it, and the connection will be made using pipes from below. At the same time, hot water flows into the pipes, completely filling the radiators. Then the water descends and enters the pipe through another pipe. In fact, it goes serial connection radiators thanks bottom connection. But there is a minus here, because at the end of such a connection in all subsequent radiators the temperature of the coolant will be lower.

Decide this moment can be done in two ways:

• connect a special circulation pump to the entire mechanism, allowing hot water to be distributed evenly across all heating devices;
• connect additional batteries in the last rooms, which will increase the heat transfer area to the maximum.

If we talk about two-pipe wiring, then for own home such a connection system will be more efficient. But at the same time initial stage the costs will be significant due to the fact that it will be necessary to separate two pipes. One must be installed to supply hot water, and the second must be connected to drain it.

When everything has become clear with this issue, you should focus on the connection diagram for the heating batteries. The most common will be the lateral one. To make it, pipes should be brought out from the side of the wall and connected to two battery pipes - above and below. The coolant supply pipe is usually connected at the top, and the exhaust pipe at the bottom. A diagonal connection will also be effective. To do this, you must first connect the pipe supplying the coolant to the pipe at the top, and the return pipe to the bottom, located on the other side. It turns out that the coolant will be transported diagonally inside the radiator. The effectiveness of such a mechanism will depend on how the liquid is distributed in the radiator. It is rare for multiple battery sections to be cold. This only happens in cases where the transmission capacity or pressure is weak.

Note that connecting the radiator from below can be not only in single-pipe, but also in double-pipe versions. But such a system is considered extremely ineffective. In this case, you will also need to install a circulation pump, which will significantly increase the cost of creating a heating mechanism and create costs for the electricity that is needed to operate the pump. If we say what should not be done, it is not to replace the water supply with return water. As a rule, debugging indicates the presence of this problem.

When installing decorative screens, the visibility of the thermostat is blocked, which is not necessary. The batteries will take a long time to heat up. At the same time, you cannot mount the thermostat head in a vertical position, as this will lead to its unstable operation.

Installing heating radiators with your own hands in your own home involves a number of issues, which do not allow us to say that this is an easy process. Its complexity also lies in the fact that in each individual case it is necessary to select batteries for a particular building, and also to know exactly how the pipes run in a private house that has already been built. Also no less important fact there will be an understanding of heating needs and carrying out all the necessary calculations.

In addition, we should not forget that there are various schemes connections and what may not be effective in one home may be an excellent solution in another. If you decide to install heating radiators yourself, then you should thoroughly study the theoretical aspects, and also, if possible, at least consult with a specialist who will tell you what you should pay special attention to during the installation of radiators and the heating system as a whole.

Which heating radiators are best to choose for your home?

Living outside the city has many advantages, but it takes a lot of effort to ensure a comfortable living environment. One of the most important points is the selection and installation of a heating system. It should not only work efficiently, but also save the family budget. And for this you should purchase the most best option heating batteries.

What factors should be taken into account when selecting a radiator

In any hardware store There is a huge range of heating equipment available. For this reason, before going to the construction supermarket, determine following parameters, on which the amount of heat required for the room will depend:

• Heat losses of the building (taken into account: decomposition of the building material (related to wood), ceiling height, number of windows and doors, glass thickness, etc.).
• Necessary temperature regime.
• The thermal power of the device is determined by the following formula: S * h*41:42, where S is the area of ​​the room; h - room height; 41 - minimum power per 1 cubic m S; 42 - nominal thermal conductivity of one section according to the passport.
• The heating radiator is usually located under the window, so it maximum size determined by the following measurements (in cm): from the floor 7-12, from the walls - 3-5, to the window sill - 10-15.

It is also important to note for yourself:

• weight (the complexity of installation depends on it);
• appearance (affects the aesthetics of the interior);
• value for money (is a determining factor).

Which heating batteries are better: types and characteristics

All heating radiators differ in design and class of material used.

There are many options according to shape and texture, it all depends on your taste preferences. Whether they will be wide or narrow, plain or colored, backlit or with designer painting - it's up to you. The main thing is that they function according to the stated characteristics.

Regarding the method of operation and the type of material used, batteries are divided into 4 classes:

• cast iron;
• aluminum;
• steel;
• bimetallic.

To understand which heating radiators to choose for a private home, you need to consider their options in more detail.

Cast iron

For more than 100 years, heating equipment made of cast iron has been very popular. This is justified by the number of positive qualities of cast iron batteries:

• Significant heat transfer (heats up to 130 degrees and remains hot for 5-6 hours).
• Durability (service life can be 50 years or more).
• High level strength (external mechanical damage, as well as high pressure inside the system will not damage the structure).
• Corrosion resistance at sharp changes temperatures and constant influence of condensation.
• Unpretentiousness to the quality of the coolant (a filter at the entrance to the heating system is not required).
• Availability (low cost).

However, due to their shortcomings, such systems are gradually being replaced by other, more advanced ones.

Cast iron heating radiators larger in size compared to other models, which makes them difficult to transport, install and maintain. They also have other disadvantages in operation:

• Low thermal conductivity. For good heat transfer, it is necessary that the coolant temperature be 70-80 degrees. (Justified by massiveness and porous surface metal).
• They require systematic maintenance (periodic painting and cleaning).
• Bulky (take up a lot of space). Do not fit into the interior of the home, although to improve them appearance can be used original fencing or partitions. There are also special design solutions from French and German manufacturers that will look good with a certain interior style. Such batteries look very nice, but their cost is high.
• Require good fastening to the wall due to the heavy weight.

Batteries are produced from cast iron in China (KONNER and Tokio) and Russia (MS-140).

Aluminum

Aluminum has significant thermal conductivity, therefore, products made from it are very productive.

Advantages:

• Ease.
• Compactness.
• Powerful working pressure (12-18 atmospheres).
• Ease of operation (sections are easy to remove/install).
• Significant heat transfer due to the shape of the sections.
• Increased heat transfer. Due to the volumetric cross-sectional area of ​​the intercollector tubes, the heat agent circulates faster and transfers heat to the metal.
• Variety of sizes.
• Acceptable price.
• Attractive appearance.

Along with the advantages of aluminum radiators, there are also disadvantages:

• Increased sensitivity to pressure differences and the composition of the heating agent (high-quality filtration and pressure gauges are required to monitor pressure during filling).
• Instability to influence chemical factors(corrosion), so pay attention to the presence of protective polymer film(coatings) on the surface of the product.
• Quick wear (function for 10-15 years).

Based on the layout of the sections, there are three categories of aluminum radiators: solid, assembled sectional and combined. But which heating radiator is better:

1. Solid is distinguished by strength and plasticity;
2. Assembled sectional panels (composited) make it possible to replace failed plates;
3. Combined - combines both functions, but also costs more. Similar systems are manufactured by the following companies: Condor, RIFAR, Global, Ferroli.

Steel

Divided into three subgroups according to structure internal system.

Panel

Rectangular radiators, consisting of two welded panels with grooves, recesses, dining channels, in which the media circulates. This heating battery is quite light and compact, allowing you to reach the required temperature in a short period of time. Another name is convectors, since heat is supplied by convection (75%).

Their disadvantages include:

• low working pressure;
• shock sensitivity;
• susceptibility to corrosion.

Manufacturers produce radiators with top and bottom connections, which allows heating to be installed in the floor. Manufacturing companies: Buderus, Lideya, Corado.

Steel sectional

They are similar to cast iron, but have significant positive differences.

• Strength provided by welded joints.
• Internal pressure of 16 atmospheres.
• Durability (up to half a century).

Although they are not available to a wide range of consumers, due to their considerable cost.

Tubular

It is worth immediately noting their high price, because they stand out for their ideal design and effective functionality. Tubular radiators make it possible to implement your own design ideas in a heated room. Produced by foreign companies: Delonghi, Zehnder, Arbonia.

Bimetallic

According to the external features, they are no different from aluminum ones. Their interior is made of high quality steel or copper. This greatly increases their safety, service life and reliability.

Despite their cost, they have long been confident leaders in the heating engineering market. Therefore, we can say with confidence: which bimetallic heating radiators will last better and last longer in your cottage will compensate for the monetary costs with the quality of their work.

Based on the above, it can be noted that both subtypes are suitable for use in private homes. Now let’s conduct a comparative analysis of a number of features and find out which of them should be preferred.

Heat volume

An aluminum heating radiator (its section) provides 200 W of energy. One part is released in the form of radiation, and the second is converted. Within 10 minutes after switching on, the air in the room begins to warm up, which provides an opportunity to save a lot of money.

In bimetallic heat transfer occurs differently: the steel core slightly slows down its spread. In principle, this indicator may differ depending on the model. Otherwise there are no significant differences.

Coolant temperature

Bimetal is capable of maintaining water temperatures up to 130 degrees, but aluminum only up to 110.

Life time

Bimetallic radiators combine the properties of two metals, and therefore their service life is longer (15-20 years) compared to their competitors (about 10 years).

Installation

Both radiators are light in weight, the steel mount is installed with screws and ordinary plastic dowels. Using a set of keys and shaped tools, components are installed and replaced.

Aluminum or bimetallic batteries, which is better in terms of service life?

In our country, the composition of water includes many chemical impurities, and since aluminum tends to react with various substances, then this is extremely undesirable for him, since rust will simply eat away his walls. For normal activity, pH should not exceed 8 units.

Bimetallic radiators are better protected by a special coating from the effects of too active a heat agent - they are not so susceptible to rust. However, there are cases of hydrogen getting into the liquid, then the components begin to rot very quickly.

Manufacturing companies are constantly improving their products. And answering the question which bimetallic radiators are better, we should highlight the brands Polywarm, Teplopribor, Royal Thermo Vittoria, Sira. One of the most famous manufacturers is Kermi, Germany.

Bottom line

The warmth in the house creates a cozy atmosphere. To always feel comfortable in your home, you need to correctly calculate the number of radiators and choose them.

By purchasing heaters for a private home based on the recommendations of specialists, you can easily choose exactly those heating batteries that are best suited for you and will satisfy your individual needs.

To keep your house and apartment warm and cozy during the cold season, it is important to properly design and install the heating system. And the radiator is one of the important components. It is thanks to properly selected equipment that the efficiency of the heating system can be ensured.

But among the rich assortment of batteries presented by such manufacturers as Prado, Conrad, Global Style, Tenrad, Viadrus, Konner and others, it’s difficult to navigate, isn’t it?

You don't know how to avoid mistakes when choosing and what points you should pay attention to first? We will help you understand this issue - in the article we will talk in detail about the criteria for choosing radiators for a private house and apartment, which are of paramount importance.

We will also consider the types of equipment and their features. We will provide recommendations for buyers, adding to them clear photos and useful videos.

The variety of heating radiators on the market is truly amazing. And it's especially difficult to do right choice to an untrained user.

Therefore, within the framework of our article, we will try to consider in detail the types of heating devices, paying attention to their key characteristics, and give recommendations for choosing suitable option, based on living conditions, type of heating system and the specific requirements of the owner.

Classifications of heating radiators

Heating devices used in the water circuit differ in design, material of manufacture, technical characteristics, and design. Next, we’ll talk in more detail about the types of radiators and their features.

What materials are batteries made from?

The most commonly used materials for heating appliances are:

• steel;
• aluminum;
• cast iron;
• combination of two metals.

Criterion #5 - manufacturer's reputation

When choosing a radiator, it is better to give preference to proven brands with a good reputation, including:

• Steel– Lidea, Konrad, Prado, Charleston, Kermi, Arbonia, Israp Tesi, Buderus PURMO, Delonghi, Korado.
• Aluminum– Global, Rifar, Ferroli, Purmo, Radena, Faral Trio.
• Cast iron– Adarad, Viadrus, Demrad, KIRAN, Konner, Cheboksary plant and Minsk plant.
• Bimetallic– Global Style, Sira, Rifar, Tenrad, Halsen, Radena, Rommer.

As you can see, many manufacturers produce more than one type of radiator, which differ in material and other characteristics.

But sometimes it is difficult to distinguish an aluminum radiator from a bimetallic one, the cost of which is much higher. This is what an unscrupulous seller can take advantage of. Therefore, before purchasing, you can conduct a test, for example, with a magnet - a magnet will always be attracted to the bimetal.

In this article we will look at what types of heating radiators there are for an apartment. How to choose a device? Which technical specifications lean on? Let's figure out which heating radiators are best for country house. Let's find out the differences between aluminum, bimetallic, cast iron, steel radiators heating systems, which ones best suit individual requirements?

NEED TO KNOW! The choice depends on the coolant components. In DSPs, the coolant is often of low quality. When in contact with liquid, aluminum is corrosive, so it is not suitable for an apartment building.

About the features of centralized and autonomous heating systems. What should you pay attention to?

Residents of multi-storey apartments and private houses (dachas, cottages) use different heating systems (OS). Each has features, advantages, and disadvantages. Keep in mind: each OS needs to select heatsinks differently. An unsuccessful purchase of equipment will lead to low heat transfer, short service life, and rapid damage.

Water hammer(water hammer) – sudden jump pressure in a water-filled system. The reason for this is a rapid change in the speed of water flow. Consequences of water hammer: the appearance of longitudinal cracks in the pipeline.

Depending on apartment building you live or privately, heating can be:

• Central (DSP). Heat is supplied to several buildings and apartments from a single source (boiler room). The pipeline distributes the coolant, supplying it to consumers. After heat is removed, the carrier returns to the source (heat generator).
• Autonomous system useful when serving residents of a private home. It is also used in cottages and dachas: they are not connected to the DSP. To heat the coolant, a boiler or boiler is installed. Next is the control unit, piping system, batteries. The advantage of autonomous control is the setting function based on needs: adjusting the heating temperature, automatically maintaining the specified settings. Flaw: high price batteries, installation work, complex maintenance.

What types of batteries are there for an apartment or private house?

Material is the main criterion by which equipment is selected. Affects heat transfer, pressure, cost, service life, strength, reliability.

According to the material:

• Bimetal. Undemanding to coolant, designed for long-term use. Expensive.
• Cast iron. The residual heat retention rate is 30% (for other varieties - 15%). Slowly heat up, slowly lose temperature. Reliable, resistant to corrosion.
• Aluminum. They heat up quickly and lose temperature quickly. Useful in autonomous systems. Characterized by high thermal power and reasonable price.
• Steel. They are compact, have good heat transfer, are durable, and are slightly oxidized by low-quality coolant.

By installation type:

• Wall-mounted. The most common radiators in apartments, cottages, dachas, and private houses. Wall mounted.
• Skirting. They are mounted in metal boxes, taking up space instead of a standard baseboard. They take up almost no room space. They are inconspicuous and will not stand out from the decor of the room.
• In-floor. Water convectors save space: they are built below floor level.

Heating radiators – which ones are best for an apartment?

When choosing a battery for installation in an apartment, pay attention to main technical parameters:

• Heat dissipation characterizes how efficiently the device copes with heating the room. When selecting, take into account heat loss (they are affected by the thickness of the walls, the size of window and doorways), volume of the room. In sectional models, the power is indicated per section. Calculating the number of fins will accurately determine the required level of heat transfer. The thermal power of one section is on average 0.15–0.2 kW.
• Operating pressure It is important that the equipment can work in your system. The pressure depends on the material. Incorrectly selected pressure will cause damage due to water hammer.

• Material or coating that can protect against wear and leaks. Thick walls and primers extend service life. The ability to connect a battery to work with aggressive coolant will expand the scope of operation.
• Design heating equipment. Consider how the heating equipment will fit into its surroundings. Due to the choice of models, the device can be selected to suit different design styles and colors.
• Weight It’s worth considering immediately before purchasing: whether you can transport the unit to your home, fix it on the wall, and connect it without causing damage. The most massive cast iron batteries, lighter aluminum (weight of one segment - up to 2 kg), steel (about 2.5 kg).

Options for choosing radiators for a country house

Unlike central system heating apartment buildings, the autonomous OS of private homes is much less demanding on pressure. Due to this, it becomes possible to purchase equipment designed for low pressure. Models with thin walls are suitable: for example, aluminum.

NEED TO KNOW! Inexperienced cottage owners are faced with freezing of liquid in pipes. This leads to the appearance of chips on the body: it bursts. To avoid this, drain the water.

Due to the smaller distance between the heat source and the battery, heat loss in autonomous heating systems is small. Equipment in a private home must be adapted to high-temperature coolants.

Cast iron heating radiators – which are better? Advantages and disadvantages

Cast iron is a strong, reliable material, heavy and durable. Cast iron heating equipment is used in apartments, private houses, cottages, and dachas. The material requires a long time to heat up, which will cause discomfort at the beginning of the heating season. But this works in the opposite direction - when disconnected, the batteries remain warm for some time.

Advantages of cast iron models:

• Long cooling time. The thick body retains heat - the heating season will end later than its neighbors.
• Reliability and durability. In old houses there are cast iron batteries that are 50 or more years old.
• Resistance to corrosion. The material is undemanding in terms of quality and type of coolant.

Flaws:

• Heavy weight. Difficult to deliver and install.
• The price is higher than steel and aluminum.
• Long heating time. It will take time to warm up.

Bimetallic heating radiators – which ones are better? Advantages and disadvantages

The peculiarity of bimetal devices is that they consist of two materials. Aluminum shell, steel core. Strong, durable. They are resistant to corrosion and water hammer, easy to install, and have high heat transfer. Due to the relatively high price and ability to withstand high pressure, they are mounted in apartment buildings. Which bimetallic heating radiators are best for an apartment? trade marks Halsen, Radena, Bilit.

Advantages of bimetallic equipment:

• High resistance to corrosion: steel components protect against harmful influences.
• High heat transfer due to the aluminum surface. Aluminum is characterized by rapid heating.
• Long service life. On average, bimetallic devices last 25 years.

Flaw one is the high price compared to aluminum, steel, and cast iron.

Aluminum heating radiators – which are better? Advantages and disadvantages

Suitable for private houses, cottages with autonomous operating system: not designed for high pressure due to the fragility of aluminum. They are inexpensive. They heat up quickly and cool down just as quickly. The service life is about 15 years.

Which radiators are better: aluminum or bimetallic?

Aluminum appliances characterized by a low price. Suitable for installation in private houses, cottages, dachas. With high thermal power, prices are relatively low (if you look at Russian manufacturers - Halsen, Royal Thermo, Radena), the design will fit into the environment.

The advantages of aluminum models include a relatively low price (there are expensive options and analogues on the market for those who want to save money), and a high heat transfer rate. Disadvantages: demanding on the acidity of the liquid (possible destruction of the walls due to the susceptibility of the material).

Bimetallic batteries made of two materials: steel on the inside, aluminum on the outside. Designed for a service life of approximately 40 years, reliable, expensive compared to other varieties. Unpretentious (no special requirements for water). The inside and outside are coated with a primer that prevents corrosion.

Bimetallic ones are suitable when a durable unit is required. The only drawback is that the price will not suit everyone.

Sectional or steel – which is better?

Sectional heating batteries are installed in several blocks: they are connected into a single structure. This is convenient and practical: it will allow you to control the efficiency of heating the room. Difficult to install: leaks are possible due to improper connection. Install such heating equipment in private homes with an autonomous operating system. This is safe because sectional models are less protected from water hammer.

Dimensions steel (panel) units are known in advance (check with technical specifications or from the seller). When choosing, focus on the parameters of the apartment or private house (volume of free space, length and depth of niches). The price of panel units is higher. The pipes of most models have a primer that prevents corrosion from low-quality coolant. The coating increases the service life. Installed in apartment buildings (riser system).
