Video: requirements for heating systems in a private house

The choice of radiators for a private house is a crucial step on which the performance of the system as a whole depends. It is allowed to combine different types radiators, taking into account the peculiarities of using specific models, and heating the house will be efficient and safe.

No matter what high-quality batteries are in the apartment, sooner or later there comes a time when they have to be replaced with new appliances. And immediately the problem is - which heating radiators are better to choose for an apartment? Another case when there is a desire to install new batteries is if the apartment has long had old cast-iron "accordions" that do not want to fit into the interior created by the owners.

The modern market offers a wide range of radiator models made from various materials and have a very aesthetic appearance. Comparing the design of modern appliances with rough cast-iron batteries or inefficient and low-quality convectors that were previously installed in apartments, of course, I want to see such novelties in my possessions.

Criteria for choosing radiators

It is necessary to approach the choice of modern radiators with all responsibility, since not all of their varieties are suitable for installation, for example, in central system heating. Some types have characteristics that are designed for a clean coolant and a certain maximum load, so they simply will not be able to withstand water hammer, which, alas, is not uncommon in our utility networks. Other radiators, on the contrary, in an autonomous heating system will not show all their potential.

In addition to the selection of radiators according to performance indicators, it is necessary to correctly calculate the number of sections in the batteries for each individual room, otherwise their efficiency will be very low, and the apartment will not be comfortable enough.

So, the effect of installing new heating devices will be expectedly high, given all their operational nuances and following all the recommended technological installation rules.

To date, several various types radiators, differing in the material of manufacture and design:

1. Cast iron batteries, both old models and improved, with an elegant modern or retro design.
2. Steel radiators - tubular and panel.
3. Bimetal heaters made of two types of metal.
4. Aluminum of various quality levels.

When choosing batteries for installation in an apartment, the following criteria must be considered:

• The maximum pressure in the central heating system in the local heating network, and the possible limit for which the vending radiators are designed..
• The maximum temperature and features of the composition of the coolant in the system, as well as the endurance of radiators to these effects.
• Material for the manufacture of devices and its main physical characteristics.
• Battery design.
• Required radiator power - based on this parameter, the number and size of sections required for efficient heating premises. These calculations are made based on the recommendations of building codes and regulations, and can be carried out in various ways, which will be discussed later in the article.

To begin with, you can give a small table, which, although briefly, but quite informatively characterizes the main types of heating radiators. Well, then consider the main types in more detail.

Types of heating batteries and their main characteristics

Cast iron radiators

Cast iron radiators are "long-lived", but do not lose their relevance today, especially since they acquire an elegant appearance and improved performance. Batteries of domestic and foreign production are on sale, and there are certain differences between them - about them a little later.

• Batteries made of this material have not lost their demand, despite the fact that other, more modern heating devices have appeared, primarily due to technical specifications cast iron. It is not subject to corrosion, radiators are not afraid of water hammer, as they have fairly thick walls. Another advantage of cast iron over other materials from which radiators are made today is its high heat capacity, that is, the ability to maintain temperature for a long time, even when external heating is turned off.
• It is also positive that cast-iron batteries will function perfectly not only in an autonomous system with a high-quality coolant and controlled pressure, but also in a central heating system. True, it is worth immediately making a reservation about that. That it is undesirable to install them in autonomous systems that work with electric boilers - operation can turn out to be too expensive in terms of high power consumption.
• Cast iron radiators, for example, which are quite suitable for installation in an autonomous open-type heating system, where the coolant is inevitably saturated with oxygen. For cast iron, this is not scary - the material is not subject to oxygen corrosion.
• The thick walls of cast iron heaters not only keep the temperature of the coolant longer, but also increase the resistance of the batteries to abrasive wear.

• If the old batteries had one standard size range, and for the proper heating of the room it was necessary to select a radiator exclusively by varying the number of sections, today devices with different power parameters are produced. This expands the possibilities of a comprehensive selection of the right radiators, both in terms of the required power and the design of the premises.
• In order to install old cast-iron batteries, it was necessary to drive brackets into the wall, which means damaging its finish. Modern batteries are produced both in a hinged version and in a floor version, with reliable legs. The latter are simply installed on the floor near the walls, and connected to the heating circuits.

• Many modern models of cast iron radiators do not have to be periodically painted, as was the case with older battery options. They go on sale ready for installation, and already have a treated and painted surface, which does not need to be refreshed with a layer of paint annually. To care for these devices, you only need a damp, soft cloth, which is used to brush off or wipe off dust. You can also notice that the absolutely smooth surfaces of modern batteries are fundamentally different from the rough sections of the old model, so dust is practically not collected on them.

• Some cast iron models of batteries are produced in very original styles. design decoration, which allows you to fit them into any interior, even modern, even executed under the "retro". It is possible to choose heating devices in such a way that they will also become a decorative element of the design of the room, complementing and transforming it.

The main disadvantage of all radiators made of cast iron is their heavy weight. If you plan to hang them on brackets, the latter must be securely fixed in the wall - and not every partition is even able to withstand such a load. In addition, to lift and hang such a battery, you will definitely need an assistant.

Cast iron radiators of domestic and foreign manufacturers

On the Russian market, you can find both domestic and imported cast-iron radiators. European countries — Germany, Italy, the Czech Republic, Spain and others — present their products in a fairly large assortment. These products differ significantly from Russian ones in some characteristics:

• Unlike traditional domestic MS-140 or MS-90, foreign products have smoother, well-finished outer surfaces, and the original retro versions are decorated with molding in the form of floral relief ornaments.

• Imported products have a higher thermal power with small dimensions. So, for example, with the same heat transfer, the volume of filling the domestic battery section with a coolant is 1.3 liters, and the Czech production is only 0.8 liters. Therefore, this option will be more compact and accurate.
• Foreign products have internal perfectly smooth cavities, which contributes to the normal circulation of the coolant, without high hydraulic resistance, and prevents the formation of deposits of dirt and scale on the walls of the channels.
• Domestic batteries go on sale with primed surfaces and require painting, while imported ones are immediately ready for installation.

• The "minus" of foreign products is their very high cost, several times higher than the price of Russian-made batteries.

In fairness, it must be said that the production of more modern cast-iron batteries is gradually being established in our country. In addition, excellent cast-iron radiators of European quality are also produced in neighboring Belarus at the Minsk Heating Equipment Plant.

Conclusion: for the conditions of an apartment, cast-iron radiators are quite applicable, especially when connected to a central heating system, of course, taking into account their characteristic shortcomings.

Steel radiators

Modern steel radiators differ both in their construction and design. They are usually made in the form of panels or pipes arranged together, which is why such heaters are called tubular or panel. To understand their design and characteristics, you need to consider each of the types of batteries separately.

Panel steel radiators

Panel radiators consist of two steel sheets, which are given the desired shape by stamping. Then the blanks are welded into a hollow panel and, if necessary, equipped with special convector elements - in order to create a vertical directed movement of heated air, thereby forming a kind of thermal curtain from the cold coming from the window.

The coloring of such a battery occurs after the assembly of all elements into a common structure. The paint is applied using a special technology that ensures the strength and durability of the coating.

In order for steel batteries to last as long as possible, the protective paint layer must be applied evenly. Therefore, when purchasing this type of device, special attention should be paid to the coating, since steel sheets can be susceptible to corrosion in damaged areas that are not protected by paint.

Panel batteries are designed for a coolant having a temperature of up to 85 ÷ 95 degrees, as well as for a standard pressure created in a centralized heating system.

The number of panels and heat exchange convector "accordions" can be different

This type of heating device usually has its own classification, which is based on the number of panels and convection heat exchangers in the finished assembly. An example is shown in the table:

Panel radiators can vary quite a lot not only in the number of panels, that is, in the depth of the structure, but also in other dimensions. Their length can be from 400 to 3000 mm, and the height usually varies from 200 to 900 mm.

In addition, panel batteries are produced with a bottom or side connection. The choice for this parameter is made depending on how the piping of the heating circuit is located.

Panel heating radiators have their advantages and disadvantages, which you should definitely familiarize yourself with before making a decision to purchase.

Towards the positives panel radiators include the following:

• Relative ease of installation of devices in the heating circuit. The radiator has a one-piece construction, and it does not need to be assembled from separate sections.
• Panel radiators tend to warm up quickly. A sufficiently large area of ​​the panel itself and the fins of heat exchangers-convectors contributes to efficient heat transfer, so the room warms up quickly enough.
• The compact size and aesthetic appearance make it possible to fit such a radiator into almost any interior.
• To fill an autonomous system with panel radiators installed in it, a fairly small amount of coolant is required.

Panel radiators also have their own significant disadvantages, which include the following:

• They are reliable at normal pressure in the central heating system, but are not designed for powerful water hammer, which often occurs when the system is filled with coolant before the start of the heating season. Panels may simply not withstand such a test. Therefore, if they are chosen for installation in an apartment, it is necessary to use a special device to protect against excessive intra-system pressure - a reducer that will smooth out the load on the panels by taking the blow.
• The internal surfaces of the panel often do not have an anti-corrosion coating, although they are in direct contact with the coolant, and the durability of their use will depend on its quality. As you know, in the central heating system, the coolant is often not of high quality, and may contain very active impurities that contribute to metal corrosion. Therefore, as a rule, a panel type of a radiator cannot be used in such conditions for a long time, since steel unprotected surfaces are not resistant to aggressive environments.

Based on the above considerations, conclusion that the installation of panel steel radiators in apartment conditions with a central heating system is undesirable.

Tubular steel batteries

Unlike panel radiators, tubular ones consist of several sections, but "tightly" fastened together by welding. Therefore, they also do not need to be assembled, since they are purchased ready-made, representing a complete structure from a certain number of sections. Therefore, in order for heating to be efficient, it is necessary to calculate the required total power required for a specific area before purchasing such radiators, and from these considerations select the optimal model.

Batteries of this type are designed for an internal system pressure of 8 ÷ 10 atmospheres, so it would be useful to install a reducer, since water hammer when filling the central system with a coolant can lead to emergency situations.

Steel radiators have a wall thickness of only 1 ÷ 1.5 mm, so the coolant quickly heats them up, and the metal begins to transfer heat into the room. However, it should be noted that thin walls are also a weak side of such batteries, as they are easily susceptible to mechanical damage.

Tubular structures are more resistant to the aggressive environment of low-quality coolant than panel structures, since they usually have an internal protective coating of polymer materials. Therefore, they are less exposed to corrosive influences and, accordingly, with other normal parameters of the system, they can last longer.

Tubular radiators can have a variety of, sometimes even "unexpected" dimensions. So, their height is from 200 to 2500 mm, depth - from 100 to 250 mm, and the width can vary widely depending on the need for total thermal power.

Tubular radiators are produced in a wide variety of design solutions, can be wall and floor. Moreover, they are installed both near the wall or window, and even in the middle of the room. For installation in the center of the room, radiators are used that have a height equal to the height of the ceiling, taking into account the supporting legs. This option is used when the room needs not only to be heated, but also divided into separate zones.

• Some battery designs are equipped with wooden panels mounted on top, and, in fact, are a bench designed for different needs, depending on the location of the heater. For example, if it is installed in the hallway, it can be used as a shoe stool, as it will be convenient to sit on it. In the evening on wooden surface can be installed to dry shoes.

Since tubular batteries are produced in different color scheme and in a variety of, even sometimes unexpected design delights, they can be matched to any interior design.

The disadvantages of batteries with a tubular design include only two main points, but quite serious, negatively affecting the efficiency and safety of the apartment heating system:

• Sufficiently low heat transfer, leading to an increase in energy costs if the batteries are installed in an autonomous heating system. The design heats up quickly, but it also tends to cool down quickly, so the heating boiler will work almost constantly, with short interruptions. The conclusion is that it is unprofitable to install them in the autonomous heating system of a private house.
• Radiator elements are connected by welding, the seams of which will become weak point in the event of a water hammer. Therefore, mounting them in an apartment circuit connected to a central heating system is also undesirable. If they are nevertheless chosen due to a suitable design, then it is necessary to install a gearbox that will take the load from a sharp pressure drop on itself.

Conclusion from what has been said : Tubular steel batteries, despite their external attractiveness, are far from perfect option. The installation of such radiators in an autonomous system will lead to unnecessary energy costs, and in the central heating system - to an increased risk of accidents.

Aluminum radiators

Aluminum batteries have an aesthetic appearance, but it must be said right away that, according to their technical characteristics, they are not very well suited for installation in a central heating system.

For autonomous heating systems, the best choice is high-quality aluminum radiators

Aluminum radiators are very popular among homeowners with autonomous heating due to their elegant appearance and high heat output. In an autonomous system with a stable pressure and a high-quality coolant, aluminum heaters can last from 15 to 25 years - these are the periods that manufacturers usually indicate in the technical data sheet as the minimum.

Radiators are designed for internal system pressure up to 15 atmospheres and coolant temperature of 80÷90 degrees. They have excellent power (heat dissipation), reaching up to 200 ÷ 210 W, and at the same time, the volume of each of the battery sections is only 450 ml with a weight of 1 ÷ 1.5 kg. The sections are fastened with the help of a threaded coupling.

Aluminum batteries can vary in size. So, the standard distance between the lower and upper axis of the radiator can be 500, 350 and 200 mm. If desired, you can find or order devices with a non-standard distance of 700 or more millimeters.

The drawing shows a 500 mm center connection with a total stack height of 573 mm.

This type of battery is made from an aluminum alloy and silicon additives that give the metal extra strength, but two different ways- extrusion and casting.

When using casting technology for the manufacture of parts, each section of the battery is cast separately by filling a special mold with a prepared alloy. This manufacturing technique guarantees the tightness of each section.

• Batteries produced by casting technology are designed for pressure in the heating system up to 16 atmospheres. During factory tests (pressure testing), the coolant is usually supplied under a higher load, which reaches up to 25 atmospheres, which indicates that the manufacturer provides consumers with an additional margin of safety for their products. Cast radiators may have various forms, but mostly they have a smooth outer surface, which contributes to higher heat transfer.

• The second, manufacturing method, according to extrusion technology, consists in forming sections by forcing the melt through special nozzles that set the configuration of the products. As a rule, the so-called secondary aluminum, a product of scrap processing, acts as a raw material here. The quality of the metal is certainly worse, since the composition of the alloy is not so balanced, the presence of impurities is not excluded. Such aluminum turns out to be more brittle, more prone to oxygen corrosion.

The finished sections are assembled into a common structure, which during operation cannot be increased by extension or reduced - a ready-assembled battery comes from the factory, which is a finished product. Such radiators also cannot be repaired - this should be taken into account when planning a purchase. Conditions of high pressure in the system, low-quality coolant, the likelihood of water hammer - clearly not for such radiators. True, the price of such heat-exchange devices is significantly lower than for cast ones.

• Another type of aluminum radiators is produced, but already with a high degree of purification of the feedstock and with anodic oxidation of surfaces. They are often referred to as anodic. During the manufacture of the original alloy, aluminum changes its structure several times - this process is carried out to achieve maximum resistance of the material to any type of corrosion. Therefore, such batteries are not afraid of the aggressive environment of any coolant.

Anode radiator sections are manufactured using injection molding technology and then assembled using threaded couplings and reliable seals. Such products can, if necessary, be disassembled, for example, to remove a damaged section, or extended to obtain the required total heat output.

The internal surfaces of the batteries, made of anodized aluminum, are perfectly smooth, which contributes to the unhindered circulation of the coolant. The working pressure of such radiators is much higher than that of conventional aluminum ones, and can reach up to 20 ÷ 25 atmospheres.

Externally, anode batteries do not differ from ordinary aluminum ones, but their cost is much higher. Therefore, when purchasing this version of radiators, it is imperative to check the product passport, which is always attached to such high-quality products.

All aluminum batteries have common "pros" and "cons", which you also need to know if you decide to choose this type for installation in an apartment.

So, the advantages of aluminum radiators include the following qualities:

• High heat dissipation.
• Light weight, which greatly simplifies the stages of transportation and installation work.
• Variety of sizes to choose from.
• Aesthetic appearance that allows you to "introduce" such radiators into the interior of any style.
• Relative safety of operation. When hitting even and smooth aluminum surfaces, it is more difficult to get injured than, for example, angular cast-iron batteries - this quality is especially important if small children live in the apartment.
• Aluminum batteries are excellent "friends" with thermostatic devices - this allows you to accurately adjust temperature regime. This quality is especially important if an autonomous heating system is created in the apartment, since the devices for thermoregulation of radiators contribute to saving on energy consumption.

The negative aspects of these heating devices are the following factors:

• High risk of gas formation in the internal channels of the structure (applies to conventional, non-anodized aluminum batteries, cast or extruded).
• Possible leakage at the connection of sections without the possibility of repair - for extruded radiators made of recycled aluminum.
• Heat concentration in the area of ​​the fins of the device elements.

Some possible problems that occur during the operation of aluminum batteries can be bypassed. So, for example, in order to prevent gases from accumulating inside the structure, it is recommended to install a special air vent for each radiator.

General conclusion: If aluminum batteries will be installed in an apartment with an autonomous heating system, then any will do, based on the financial capabilities of the owners and taking into account all the above disadvantages. If the apartment is connected to central heating networks, it is recommended to choose only radiators made of anodized aluminum - it is more resistant to aggressive environments, high temperatures, and pressure drops in the system.

Bimetal radiators

Bimetallic radiators are currently the most popular of all types of modern batteries, second only to traditional cast iron batteries.

These heaters are manufactured according to combined principle- they are assembled from parts made of two different materials, which, in fact, is clear from the name. So, the outer part of the battery is made of aluminum, which has maximum heat transfer, and the internal channels for the circulation of the coolant are made of high-quality steel alloy that is not subject to corrosion. Aluminum external surfaces have a protective enamel coating, which gives the radiators an aesthetic appearance.

Of course, if you plan to purchase a non-separable radiator, which is a one-piece structure, then divide by the specific power of the section Pc- is not necessary, that is, this part is simply excluded from the formula. The resulting value will show how much total radiator power is needed for this room.

However, these formulas will be valid only for standard average conditions. Therefore, when calculating the radiator by the area or volume of the room, it is important to take into account the correction factors that are determined by the minimum winter temperature in the region of residence, the location of the room, the quality of the wall insulation, the number and type of windows, the presence of a door to the street or balcony. Moreover, even the location of the batteries and the scheme of their insertion into the heating circuit can be of considerable importance for calculating the thermal power.

There is probably no point in listing all the correction factors and giving a rather cumbersome calculation formula in this article. It is better to invite the reader to use a convenient calculator, which already contains the main dependencies.

Calculator for calculating the required heat output of heating radiators

For the calculation, it will be enough to indicate the requested data. The calculator will allow you to determine the number of sections of the selected type of radiator. If the calculation is made only to determine the total thermal power required for high-quality heating of the room (for example, to select non-separable models of steel or aluminum batteries), then the field with the requested specific nameplate power of one section is left blank.

For right choice heating radiators you need to know about their main technical parameters. Otherwise, the result may not meet expectations. There are not so many really important parameters for radiators, so even a non-professional can easily understand them.

Features of the choice of heating devices

Now people no longer need to hide or, because modern appliances can become a worthy decoration of any interior. Radiators that are sold today may differ in color, size, material of manufacture and general style of execution, so it will not be difficult to choose the most suitable option.

Attention! Despite the fact that we are accustomed to light-colored batteries, the heat dissipation of black devices is approximately ¼ higher due to color alone. Although when choosing a color it is better to focus on the design of the home and personal preferences.

With regards to the form, it must be streamlined. For security reasons, it is advisable to refuse sharp corners altogether, especially if children live in the house. Read the strengths and weaknesses of each before buying. existing species radiators to determine which is more suitable for a particular room. The first thing you should pay attention to is the working pressure of the devices.

Depending on the material, radiators are divided into:

The pressure mentioned above, the heat transfer coefficient, heat capacity, resistance to mechanical and chemical damage, as well as the service life depend on the material.

Also pay attention to the method of connection to the heating line. The connection can be side, bottom and universal. It is characteristic that in modern radiators all these connection methods are provided.

Attention! The environmental friendliness of the material used in the manufacture of heating devices is also very important. There should be no formaldehyde in the internal elements, and high-quality polymer spraying on the surface is also welcome.

Now in more detail about each material.

Characteristics of aluminum radiators

Heating appliances made of are considered one of the most popular types of radiators. Aluminum is a light and ductile metal, therefore, batteries made from it weigh a little and are characterized by increased heat dissipation.

The devices consist of sections, each of which is a set of interconnected plates. Thanks to this, heat saving is also at a fairly high level here.

Advantages such units are as follows:

At the same time, after turning off the heating, such radiators cool down quite quickly. Among the others shortcomings worth highlighting:

• instability to chemical influences (the problem can be solved by polymer spraying on the inner surface);
• low strength;
• poor quality of the threaded connection in the upper valve to bleed air from the system.

In view of this, before buying, it is imperative to inquire about the operating pressure of the heating system. The maximum pressure of a particular product must be viewed in the data sheet, because for different models it is different.

But still, according to its characteristics, aluminum is excellent for the manufacture of radiators, and its fusibility has made it possible to significantly expand the model range. Today you can choose exactly the battery that fits perfectly into the interior of your home.

Characteristics of bimetallic batteries

The main difference between bimetallic radiators is the use of two different metals in the manufacturing process - steel to create the core and aluminum to assemble the case. Thanks to this, the rod is very durable. Another advantage of such products is the high working pressure, which can reach 50 (!) Atmospheres. Moreover, steel perfectly "cooperates" even with the water in which there are various impurities, while aluminum heats up quickly and gives off maximum heat.

In a word, the use of two metals at once made it possible to obtain radiators that have the advantages of each of them. Therefore, it is quite obvious that the cost of these devices is the highest among all possible options.

Attention! are used mainly for heating industrial and public facilities. In residential buildings, they are rare due to the high cost.

The service life is 20-25 years, which is quite normal.

Table 2. Comparison of bimetallic radiators

All the advantages of using bimetallic radiators are clearly expressed in the design of STOUT Space heaters. These radiators are easy to mount, they are suitable for rooms of any design and have reliable designs. The maximum pressure that the heater can withstand is 100 atmospheres. Production - the Russian plant "RIFAR", the largest in the country. Service life - 25 years, manufacturer's warranty - 10 years. available from 4 to 14 - you can complete any object and choose a radiator for a room of any size.

Characteristics of cast iron radiators

Such batteries are the most common and well-known to each option, since they are installed in most of the typical apartments. Agree, old cast iron appliances can hardly be considered stylish and attractive. New models look better, but in terms of aesthetic indicators they are still significantly inferior to devices made of other materials.

As you know, cast iron is very heavy. Batteries made from it weigh a lot, which cannot but affect the complexity of transportation and installation.

Consider their main advantages.

But cast iron has flaws, among which:

• significant weight;
• slow heating;
• unaesthetic.

Attention! Despite the abundance of more modern analogues, many people prefer to install cast-iron batteries, trusting what has been tested for decades.

Table 3. Comparison of cast iron batteries from the most famous manufacturers

Cast iron radiators

In the manufacture of these devices using low-carbon steel. In order to protect the surface is coated with a special enamel. If of good quality, then they have excellent operational parameters, including:

• strength;
• reliability;
• resistance to corrosion;
• durability;
• resistance to various kinds of aggressive substances.

Such batteries can be tubular and panel.

Tubular appliances

For their assembly, high quality polymer-coated steel pipes are used. The maximum load that the devices can handle depends solely on the thickness of the pipe walls. It is desirable that the pipes are made of stainless steel.

The service life of tubular devices significantly exceeds that of panel devices and is about 30 years. It is possible to connect in all the ways described above. The working pressure is 10-16 atmospheres, more detailed data should be clarified in the product data sheet.

Outstanding representatives tubular radiators are models manufactured by Loten:

• Loten Gray V;
• horizontal LotenGrey Z.

These radiators are made of a steel profile pipe with a rectangular cross section. In addition to providing comfortable heating, the presented radiators demonstrate the latest trends in the design of heating devices, perfectly fitting into the interior of any home.

When creating Loten tubular radiators, there were two main ideas:

• to create high-quality heating equipment: for the manufacture of radiators, high-strength metal with a wall thickness of 2.5 mm is used, due to which these heaters have a working pressure of 16 atm. Radiators withstand a test pressure of 25 atm;
• at the same time turn the battery into a stylish element of the interior of a home, office space, location common use etc.

The presented models of heaters can have a different number of sections, from 4 to 12. The length of the sections varies from 750 to 2000 mm. The price of each heating element is directly dependent on the following parameters:

• number and length of sections;
• connection type (side/bottom).

Without extra charge, you can purchase radiator models painted in colors that are at the peak of popularity regarding interior design:

• matte black;
• classic white;
• soft beige;
• concrete grey.

However, lovers of a bright environment can order any other colors and shades.

The presented models of radiators are suitable for connection to a central as well as an autonomous system. The size range is really wide, you can equip the presented radiators as a cozy small one-room apartment, and a spacious country mansion.

Each model can be with side or bottom connection. Heating systems that are suitable for this battery can be:

• single-pipe;
• two-pipe.

The high quality of the material and the laconic style of the products will allow them to take place for many years not only in the apartment, but also in the list of your preferred interior items. Their peculiarity is that they have a long service life (warranty - 5 years, service life - 30 years), so you will not have to think about changing batteries soon. So, you can confidently trust the manufacturer, and make a choice in favor of the considered devices.

Panel devices

As the name suggests, such radiators are made in the form of panels. To do this, a certain number of steel plates are connected to each other. Thanks to this assembly, a high heat capacity is achieved, while the thickness of each individual plate is negligible. In addition, they weigh a little and provide the ability to connect in all available ways.

Attention! Before buying new heaters, look at how your old ones are connected. It is advisable to have new batteries as well.

The cost of panel radiators is slightly higher than the average, the operating pressure is 10 atmospheres. According to experts, such units are best used in autonomous heating systems. As for city apartments, the use of such batteries is unacceptable here due to too high pressure in the central system.

As a conclusion

It should be noted that any of the described types of batteries can be used for residential heating systems. Although the purchase of bimetallic devices is often impractical, because their advantages are almost the same as those of aluminum, and the cost is many times greater. Therefore, it is better that they continue to remain in industrial and public facilities.

It is undesirable to install aluminum appliances in apartments due to pressure drops in the system that negatively affect the metal. The optimal and proven option for apartments for years is cast-iron batteries. One way or another, you need to focus on financial capabilities and personal wishes.

For those who do not want to dive into independent calculations, we recommend using a special calculator for calculations, which takes into account almost all the nuances that affect the efficiency of space heating.
