Aluminum heating radiators are designed for operating pressures up to 12 atm. Due to light metal, they do not create a load on walls and pipes. Such batteries quickly give off heat and help to effectively regulate the temperature in the room. Bimetallic structures contain a steel collector inside and an aluminum outer shell. This design allows you to operate them with a working pressure of up to 35 atm and extends their service life up to 40 years. The designs are varied and attractive. But such products cost more. Here is a rating of manufacturers who have won worldwide recognition in the production of just such products.
The championship in the ranking belongs to the Italian manufacturer Fondital Mood. This company has been producing various products for heating domestic and commercial premises for more than 40 years. The company's catalog includes aluminum and bimetallic radiators. The dimensions of the elements have a center distance for connection from 235 to 2000 mm and are manufactured in horizontal and vertical versions with side and bottom connection. The manufacturer uses a single standard for connecting the fitting - G1 threaded pipes, which customers like in the reviews.
Our experts put the manufacturer in first place in the ranking, because the radiators of this company are not just heating elements, but a work of art. The company pays great attention to the external design of goods. For example, designer aluminum radiators have decorative legs (although it is attached to the wall) that create the effect of being installed on the floor. Other models feature molded floral sections.
The second place in the rating was also taken by the Italian company "Global", whose slogan translates as "Global warming in your premises." The manufacturer specializes in the production of bimetallic and aluminum heating radiators, designed for a coolant temperature of 110º C, which exceeds the rating leader. But the design of the heating panels of this company is much simpler. Mostly used sections with a square section and additional plates that accelerate heat transfer. But buyers in the reviews like their color, which is not pure white, but beige. By the way, the paint here is powder coated and applied in two layers, so the batteries are resistant to chemical detergents.
We placed the manufacturer in the ranking of the best because of its Global Style Plus line. This is a special series of bimetallic heating batteries, designed for pressure up to 35 atm. To prevent leaks, the manufacturer uses high-density silicone gaskets that tolerate temperature deformations of the metal well. This is the best choice for a multi-storey building or a large building where a boiler with a powerful pump works.
The third step of our rating was occupied by a European manufacturer whose products are actively sold in Russia. Products for heating comply with international and domestic quality standards. Aluminum and bimetal radiators are made by injection molding. To them, the manufacturer offers a large selection of pipes and fittings that fully correspond to the mounting pipes. This allows you to buy everything in one place and like buyers. Masters in the reviews share that despite the youth of the brand, the batteries are quite high quality and rarely leak, but their price is much more affordable than competitors. The total heat output from four sections with a height of 41 cm will be 536 watts.
We included the manufacturer in the rating, since its heating products are quite high quality, despite the affordable price. During testing, the radiators are pressed with a pressure of 30 atm, which protects against leakage during operation. More batteries are designed for water or antifreeze temperatures up to 135 degrees. This is a rarity for heating systems and allows even steam to be used inside them.
Fourth in our ranking is the IPS brand, owned by the Italian manufacturer Sira Industrie, which has been operating since 1958. The company received its first patent for an aluminum radiator in 1961 and has since continued to lead in Europe in this industry. The company produces high-quality radiators with a center distance of 50 cm. The 6-section model has an increased thermal power of 678 W, which customers like in the reviews. Despite the dimensions of 480x565 mm, the weight of the product is only 11 kg, without creating a load on the wall.
Our experts liked the manufacturer for its responsible approach to quality control, for which it was added to the rating of the best. Each heating radiator is subjected to a pressure test of 52 bar, which not all companies do. This allows you to freely operate batteries at 30 bar without fear of fluid sections. Another line of bimetallic models, Elegance Wave Bimetallico, has an attractive curved shape of the front panels, making the design of the batteries more attractive.
At the fifth step of the rating is a domestic manufacturer that actively uses foreign technologies. The company has been operating since 2002 and all production is carried out in Russia. But foreign equipment from Buhler, LEAS, ABB, Insertec, Maicopress is used for production. The catalog contains a large selection of products in the series: Pianoforte, Tower, Biliner, Revolution Bimetall. Consumers in the reviews like the high protection against counterfeiting - each product has a nameplate with the brand logo attached in the upper right corner. This additionally serves as a decorative element indicating expensive products. The manufacturer offers high-quality Nano painting, which is implemented in seven stages.
We added the manufacturer to the rating due to the provision of a guarantee for bimetallic heating radiators - 25 years. This is a serious claim and it is supported by facts. Batteries really last such a long time, since the core is completely steel. This manufacturer also has stylish black radiators that turn heating elements into part of an unusual interior.
The sixth place in the rating was given to Lammin. The manufacturer of tori for heating promotes the philosophy that the time of cast-iron batteries has passed, therefore, only aluminum and bimetallic models, as well as a lot of fittings, are in the assortment. The enterprise has been operating since 1989 and today its products are recognizable in the markets of Europe and Asia. The manufacturer offers two product lines Premium and Eco. The first line is guaranteed for 10 years, and for the second 7 years. Consumers note in the reviews that the Premium series supports work with coolants up to 120 degrees and can withstand pressures up to 24 atm. At the same time, heat up to 180 W is given off from each section. The Eco line is designed for economical organization of heating in a modern style. It can withstand temperatures up to 100 degrees and produces 100 watts.
We added the manufacturer to the rating due to the increased weight of the radiators. Despite being cast in aluminium, each piece weighs 0.5-1.0 kg more than the competition. This was done to improve efficiency. The increased heat removal area increases the heating capacity and saves fuel costs.
Seventh in the ranking is a domestic manufacturer that produces products for heating in China. This is due to easier doing business, taxes and other factors. The aluminum alloy used for the manufacture of radiators meets the quality standards of GOST 1583-93 and EN 1706. Production is carried out on the equipment of Marconi (Italian melting furnaces), Wagner (German painting station), Sir (Italian radiator processing line). Goods from the factory are equally supplied to Russia, France, Romania and Poland. The consumer has a choice of light models Optima and Plus, as well as heavier models with increased power Profi and Profi Bm. For connection, two center distances of 350 and 500 mm are offered.
We placed the manufacturer in the rating due to the optimal ratio of price and quality. The domestic brand is maximally adapted for operation in harsh conditions and for low water quality. The batteries of this company are also insured by Ingosstrakh for 8,000,000 rubles in case of damage to property, health or life, which inspires confidence and is liked by buyers in the reviews.
The eighth position in the rating is occupied by another domestic brand that produces products for heating in Russia, in Volgograd. The manufacturer uses German technology and equipment for aluminum die casting. This ensures precise shapes without burrs or protrusions. Radiators with 4, 6, 8, 10, 12 sections are available for purchase. The company deals only with aluminum and bimetallic models. All products are powder coated in RAL 9016 (white). When tested, a pressure of 38 atm is applied to the battery, and if the design is sealed, then it goes on sale and is designed to work with 25 atm. This margin of safety is liked by consumers in the reviews. The heat output from each section is 127 watts. Radiators with a thickness of 80 mm are produced, and the distance between the connection pipes is 35 and 50 cm.
Our experts included the manufacturer in the rating due to the provision of a 20-year warranty. It's a bold move to compete with more established brands and allay fears. There are more than 500 representative offices of the company in Russia, so finding a master to fix a leak or replace a defective product for free will not be a problem.
Steel radiators are cheaper and more compact. They can work with a pressure of 8-15 atm. The service life is 20-30 years. Relatively light weight simplifies installation. The weak point of such products is susceptibility to corrosion. Products from manufacturers in this rating category are a great opportunity to save money on repairs.
The first place in the rating belongs to the German manufacturer Dia Norm, which organized the production in the city of Winnenburg. All products are ISO 9001 certified. The plant is owned by the Finnish group Rettig. The quality of the goods speaks for itself. For the production of steel radiators, low-carbon cold-rolled steel FePO1 is used. The profiling step is 3.3 cm. Radiators are manufactured with a height of 250-950 mm and a length of 400-3000 mm. The company deals only with panel types - tubular systems are not used. In total, the company's catalog offers three series: Plus, Ventil and Ventil M. They are divided into four options by depth, which affects the thermal output. Batteries can be used in both two-pipe and one-pipe heating systems, which customers like in reviews.
We added the manufacturer to the rating because of the revolutionary approach to heating installation. The Ventil M series is available with bottom center connection. This is practical for accurate piping in multi-storey buildings and does not require the selection of goods on the side of the nozzle (left or right).
The second in the ranking is the Kermi brand. It belongs to the Swiss company Abronia Group. Radiators are produced at factories in Germany and Turkey. The company specializes in the manufacture of steel panel models of both standard sizes and with a height of up to 200 mm, which allows them to be placed along the room, not necessarily under the windows. Customers like such rare models in reviews because they are suitable for organizing heating with non-standard solutions. The manufacturer's products are also distinguished by large batteries for 12 plates, having a depth of 6.4 cm, which is rare for large radiators.
We included the manufacturer in the rating thanks to a special design line of steel radiators, which are designed specifically for bathrooms. In addition to the practical part of heating and drying towels, they serve as a real decoration. For example, the Tabeo series with flat horizontal panels creates an entire warm wall. Casteo are similar in configuration, but have a larger distance between the flat lintels. The Duett radiator allows you to place up to 5 towels on it at the same time.
In third place in the ranking is the German manufacturer Bosch, which moved its factories to Russia, to the city of Engels. It is there that the production of goods under the Buderus brand is carried out. For the production of steel radiators, cold-rolled metal sheets with a thickness of 1.2 mm are used. The products of the Magnitogorsk Iron and Steel Works are used as raw materials. Each model is tested for tightness and complies with GOST 31311-2005. Customers are offered batteries with a height of 30-90 cm and a length of 40-300 cm. Thermal power varies from 136 to 15083 watts. The owners in the reviews report that the radiators of this manufacturer can be bought in any size, because they are always in stock. This is important so as not to delay the repair time, as in the case of waiting for specific dimensions from European factories.
Our experts put the manufacturer in the rating due to the production of multi-row heating radiators without front and rear designation. This configuration without a backplate allows the battery to be rotated to either side for mounting, depending on the location of the nozzles and the convenience of connection.
The Purmo brand is owned by Rettig Heating. The concern is engaged in heating systems, mechanical engineering and real estate. Purmo products are supplied to Europe, China and Japan. The British Standards Institute awarded the manufacturer ISO 9001 and 14001 certificates, emphasizing proper quality control. Unlike the more well-known Dia Norm range, this brand is aimed at consumers with low incomes, so the price is what buyers are talking about positively on the forums. The official website of the manufacturer is convenient for choosing batteries, since the products are divided not only by the names of the lines, but also by the place of installation (living room, bedroom, bathroom, etc.).
Experts liked the manufacturer with a wide range of available products, for which it was included in the rating. The company offers steel radiators of standard sizes in the Compact, Ventil, Hygiene, Plan series. There are five types of low profile radiators for installation under large windows. Kos, Fabo, Narbonne and VT decorative batteries are produced in a special line. The manufacturer did not forget about the tubular radiators represented by the Laserline, Twin, Bar and Column Bench lines.
The domestic company "KZTO" completes the rating of this category. The plant has been operating since 1997 and has developed a wide range of steel heating radiators. Products comply with European standards, which is confirmed by quality certificates, which can be found on the official website. The manufacturer deals exclusively with steel products and offers an economical line "Harmony" with thick vertical pipes, "RSK" with thin jumpers, "Parallels" with a horizontal arrangement. There are also original solutions for the bathroom that customers like in the reviews - the "Mirrors" line with high vertical pipes, between which a mirror is placed.
We put the manufacturer in the rating because it offers an interesting line of steel Solo radiators that imitate aluminum ones. The two manifolds are connected by flat panels that look like more expensive competitor products. At the same time, the depth of the heating elements is 42 mm and will fit even under a window without a niche. The company also offers to paint the panels in any RAL color from the catalog.
Cast iron retains heat for a long time, so heating becomes efficient. But quickly lowering the temperature with such batteries is more difficult. The advantage of cast iron is a service life of up to 50 years, and a serious disadvantage is its high weight. They need to be securely fastened to the wall. The design of these products is varied. For those who love the classics and want to make repairs once in a lifetime, choose heating elements from this category of manufacturers in the ranking.
The first place among the manufacturers of cast-iron radiators is occupied by the Turkish company Demir Dokum. The company has been dealing with heating systems for about 60 years and has accumulated solid experience. The company offers several options for cast-iron batteries in a modern style, completely different from the old radiators from the USSR. The radiators are pressurized at the factory with a pressure of 15 bar and are designed for continuous operation with 10 bar. The depth of most models is 250 mm, but there are also narrower options by 100 mm, which buyers like in the reviews.
Our experts placed the manufacturer in the rating because of the interesting design of some lines. For example, Nostalgia is produced in a retro-style form, but equipped with a casting pattern (leaves, weaving). The Tower Series is designed with clean lines and flared legs reminiscent of a tower. Historic have chasing for painting. All this gives ample opportunities not only to create efficient heating, but also allows you to decorate the premises.
The second in the ranking is the manufacturer GuRaTec. It is a German brand with proven quality and a price to match. For organizing heating, the company offers several style lines: Apollo, Artdeco, Merkur, Jupiter, Diana, Flora, Fortuna. In terms of the number of sections, a cast-iron battery can be 5-15 elements with a total length of 41-118 cm. Before being released for sale, the product is tested in Berlin for tightness with a pressure of 10.5 bar. The working indicator is 8 bar.
We have added the manufacturer to the rating, because in addition to interesting casting, it offers artistic processing of heating elements. Sections are painted "under gold", on a black or white background, which makes the final product even richer. Buyers in the reviews share that the company also has matching valves with carved, ornate decorations that complement the overall design. But such a design, of course, will not fit into the usual "Khrushchev". The goods are designed for cottages and exhibition halls, museums.
In this place of the rating is a domestic manufacturer specializing only in old-style cast-iron heating elements. The company is engaged in the production of its own batteries and takes running models of competitors for decoration, improving their appearance. It is noteworthy that in Istanbul, in the Dolmabahce Palace, such radiators have been operating for more than 100 years. Artistic casting provides for the creation of an unusual ornament in the Eclectic style, which originates in the 19th century. These are reliable and efficient models with a thermal output of up to 187 watts. The height of the panels varies from 50 to 90 cm.
In our opinion, the manufacturer should have been added to the rating due to the variety of colors. Customers can choose any color according to the RAL catalog and receive heating elements that best suit the interior of the room (pink, blue, etc.). It is also one of the few companies that imitates scuffs on radiators, visually aging them.
The fourth position in the ranking of the best manufacturers of cast-iron radiators belongs to the Czech company Viadrus. The company has been operating since 1888 and was originally engaged in the production of cast iron batteries, as well as solid fuel heating boilers. Today, the manufacturer offers the series: Kalor (classic ribbed design), Bohemia (artistic casting with painting), Dafne (high relief patterns). Buyers respond positively to the economical Styl line, which is distinguished by sections with an elongated triangular shape. This configuration requires less cast iron to produce, and the heatsinks are lighter.
We added the manufacturer to the rating because we liked the Termo line. These are cast-iron radiators with a panel outer board. The design is specially designed for a reduced amount of coolant and an increased area for heat transfer to the air. Such radiators do not look pretentious and are suitable for a modern apartment.
Our rating is completed by the manufacturer Konner, which has been producing heating equipment for the past 20 years. There are two types of cast-iron batteries in the company's catalog: Legenda and Modern. Products from the first series are refined and expensive, designed for a pressure of 12 bar with a test at 18 Pa. Their thermal power reaches 180 watts. The second series is more affordable and compact. Flat panels are easier to clean, but the heat output is much lower at 80 watts. The masters in the reviews like the center distance of 50-60 cm, which allows you to replace old Soviet batteries with new ones without altering the system (only a fitting).
We marked the manufacturer in the rating as the most reliable. The company gives a guarantee for radiators made of cast iron for 15 years. Not all competitors provide such a service. Another product for heating Konner is certified in Russia and insured by Ingosstrakh for half a million dollars.
They are the most modern radiators among those currently existing. They are mounted without problems, allow you to get a lot of heat, and look attractive, in addition, they are not able to spoil the interior design. However, different radiators are sold in stores today, which differ in technical and design characteristics. Which of them is better to choose, you can find out if you read the rating by manufacturers and features.
Considering the rating of bimetallic heating radiators for the home, one cannot fail to mention Russian goods. One of the most famous is Rifar. It is located in the Orenburg region and manufactures devices, the price of which for one section varies from 500 to 900 rubles. Thermal power can vary from 100 to 200 watts, working pressure does not exceed 20 bar. The temperature of the hot water circulating inside can reach 135 °C. If you are interested in patented radiators, then you can consider RIFAR MONOLIT, which is quite often called by consumers as a company that produces some of the best appliances on the domestic market. They are able to withstand pressures up to 150 bar, and sectional thermal power varies from 134 to 196 watts. The operating pressure can reach 100 bar and the hot water temperature limit is 135 °C.
These devices are popular for installation in central heating systems. In them, the manufacturer took into account the requirements and features of the operation of domestic heating systems. On sale you can find models with a center distance of 200 and 350 mm, this allows you to maintain style in rooms with different height restrictions at installation points. A feature of these radiators is a closed rear surface, which allows the radiator to be used in combination with French windows. The coolant in such batteries can be specially prepared water according to the rules for the technical operation of stations and networks. The company gives a 25-year warranty on its products, promising trouble-free operation for 15 years. At the same time, it is necessary to observe the rules of operation, transportation and installation.
Before purchasing the described devices, you can consider the rating of bimetallic heating radiators. It is important to pay attention to the manufacturer. For example, the South Korean company MARS manufactures equipment based on a copper core. The price for one section will be 400 rubles, and the hot temperature limit is 130 ° C. Sectional heat transfer is 167 watts, as for the operating pressure, it can be maximum 20 bar.
It would be fair to note the Japanese company REGULUS-system, which manufactures radiators with a copper core. By purchasing this product, you can count on a 25-year warranty. The working pressure of these devices is 15 bar, and the temperature of the circulating water can reach 110 °C. Chinese manufacturers also supply their heating products to the market. Their radiators are cheaper compared to well-known brands, but they have attractive designs and good finishes. With a modest budget, you can buy radiators from a Chinese manufacturer, however, as practice shows, they are able to endure less impressive pressure.
Bimetallic heating radiators, the rating of manufacturers of which is presented in the article, are also offered for sale by South Korea, which operates under the Mars brand. These products are favorably distinguished from competitors by specific consumer characteristics, which are focused on the use of heating devices in Russian systems. In this case, the equipment may be subjected to unstable overpressure and low quality coolant.
The described option is an ideal solution, which is characterized by high wear resistance, efficiency and energy savings. The rating of bimetallic heating radiators for an apartment would not be complete without this company, which manufactures radiators with a copper manifold, which completely eliminates corrosion manifestations.
The unique characteristics of bimetallic batteries make it possible to replace the usual cast-iron radiators, while the heat transfer efficiency and durability of the new radiators are not inferior to traditional ones, and in appearance they are much superior to old models. Batteries of this type are successfully used for organizing heating of a country cottage and for installation in multi-storey city houses. The steel core is able to cope with the powerful pressure characteristic of centralized networks, and is also resistant to water hammer, from which urban heating plants are not immune.
In addition to strength characteristics, bimetallic products show high resistance to aggressive environments, which is important in urban environments, when the coolant is subjected to excessive alkalization or there is an increased acid content in it.
These devices are light in weight, look attractive, they have a high level of heat transfer and a long service life. It is not difficult to choose a radiator of the required size, as manufacturers have launched the production of various models.
The devices in question have positive properties that distinguish them from other types of heaters:
The negative qualities include the following points:
When choosing a radiator, you should pay attention to its technical characteristics, which are reflected in the product passport. Typically, the following information about the device is important for the consumer:
Radiators of this type are produced using a complex technology by combining two types of metals. The basis of the product is a steel frame, inside which the movement of the coolant passes. The rigidity of the steel allows it to successfully withstand high pressure, as well as resist corrosion.
Outside, the frame is clad in an aluminum casing. Aluminum is able to quickly heat up and transfer heat to the atmosphere. Also, the casing is equipped with special fins that direct the flow of warm air into the room.
Prefabricated models are fastened together using nipples with the installation of rubber gaskets. Such connections can withstand temperatures up to 200°C and network pressure up to 35 atm. Cast models have no internal connections.
Bimetallic radiators are produced in two types:
The convenience of sectional models lies in the ability to build new sections as needed. It will not be possible to increase a monolithic battery in this way, but due to the breadth of the size range of radiators, they can be selected for any task.
The cost of monolithic models is higher than sectional models by 20-30%.
For heating devices in residential premises and office buildings, both types of bimetallic heating radiators are used. Which is better for an apartment - depends primarily on the design of the heating system. For standard apartments in high-rise buildings, it is better to use cast products, and in a country house, sectional ones will also cope with the load.
To decide which radiator to choose, it is necessary to take into account the peculiarities of the organization of heat supply at home and the following characteristics of the heaters themselves:
Monolithic cast products withstand significant pressure and water hammer, so they should be installed in multi-storey buildings. Sectional products are not able to withstand such tests due to the weakening of the structure by the threaded connection of individual parts, but such heaters are easy to maintain and, if necessary, build up, which is impossible in the case of cast batteries in a private house.
In addition to standard radiators made of steel (or copper) and aluminum, semi-bimetallic heaters are produced. In these products, the inner core is made not only of steel - it also contains elements of aluminum. Usually aluminum is used to install vertical pipes.
Such a replacement of the base material significantly reduces the strength characteristics of the product, and in terms of durability in aggressive heating systems, semi-bimetallic radiators differ little from conventional aluminum batteries. The junctions of an aluminum pipe with a steel pipe become unusable very quickly due to the difference in the coefficient of expansion of these metals when heated.
Semi-bimetallic radiators are slightly lighter than the original, so when buying, you should pay attention to this point, as unscrupulous manufacturers may not indicate the exact parameters of the product. These heaters are closer in characteristics to aluminum ones, so it is better to install them in a private house.
All types of produced bimetallic radiators are subdivided according to the distance between the inlet and outlet. Most often, the distance between the axes is 350 or 500 mm, but some manufacturers make batteries with a center distance of 200 and 800 mm.
Most of the bimetallic batteries are made with a steel frame and an aluminum shell. The steel core perfectly copes with the excess pressure of the network, resists corrosion, and the aluminum shell serves as an excellent heat diffuser. Some manufacturers use high-carbon steel grades, which makes it possible to achieve higher strength characteristics and product durability.
Core. The more expensive, but the best version of bimetal radiators, include batteries with a copper core. This is actually an eternal material with high strength. The service life of such products is at least 50 years.
There are many models and brands of bimetallic batteries in retail chains, both domestically produced and foreign analogues. The rating of bimetallic heating radiators for an apartment in terms of reliability includes several well-known manufacturers.
The most famous and reliable manufacturers include the following companies:

The most popular and high-quality models include the following bimetallic radiators:
To calculate the required number of radiator sections for efficient space heating, you will need to determine the area of the room and know the heat transfer power of one section in watts. It is believed that 0.1 kW (or 100 W) of thermal energy per square meter is enough to create comfortable living conditions, which means that the following calculations must be carried out to obtain the required number of sections:
The formula for calculating the number of sections looks like this: K=P*100/M
If necessary, you can install bimetallic heating radiators yourself. Before starting work, you should read the instructions that came with the equipment and correctly calculate the location of the battery.
The radiator must be placed in the middle of the window opening, the distance from the installation surface is from 3 to 5 cm, the distance from the floor and the window sill is at least 10 cm. Having marked the installation location, you can proceed with the installation. The sequence of actions is as follows:
Upon completion of all work, the protective film is removed from the surface of the radiator.
Recently, more and more often you can find bimetallic radiators, which replace ordinary cast-iron radiators inherited from Soviet apartments. New options are not only more convenient, but also more beautiful. They can differ significantly in appearance, as well as technical characteristics. However, it is possible to determine which bimetallic heating radiators are better to choose only after certain calculations have been made. If you install batteries with a small number of sections, or an insufficient degree of heating, it will be cold in winter. Therefore, you need to choose bimetallic radiators carefully, especially for residents of the northern regions of the country.
Basically, these types of radiators are purchased for apartments. Depending on the characteristics of the room, its dimensions and location in the house, certain batteries can be effective. The owner of the apartment must take into account all the indicators, otherwise a new and beautiful radiator will not be able to heat the room as efficiently as its cast-iron predecessor.
Bimetallic radiators may differ in appearance, size and type of connection. One of the most popular options is the bottom-connected battery, as it has its advantages. However, it will not be able to optimally heat the room if the number of sections and the power of the radiator do not correspond to the required indicators.
Therefore, before buying, it is necessary to carefully calculate the sections by area. It should be borne in mind that not only the power of 1 section is taken into account, but also many other indicators. This is the only way to correctly calculate the required dimensions of the battery and buy a truly efficient heater.
The number of sections of bimetallic radiators depends on the power of the radiator and the area of \u200b\u200bthe room, the height of the ceilings
The width and depth of the radiator section also play a role.
Experts pay attention to the fact that a bimetallic radiator has a slightly higher heat transfer than a cast iron one. If the coolant temperature is 90 degrees, then the heat transfer from the bimetal will be at around 200 units, and from cast iron - 180. Thus, by purchasing a new bimetallic heating battery of the same power as the previous one, we can expect more heat transfer.
The advantage and design feature of a bimetallic radiator is that the pipes inside the radiator that come into contact with water are made of steel, and the outer shell is made of aluminum, which improves thermal penetration.
In terms of heat transfer, a bimetallic radiator can be compared in efficiency only with a cast iron one.
A new radiator will work better anyway. The thing is that over time, the pipes become clogged, and the efficiency of the radiator drops.
The easiest option for calculating battery power is to count the number of sections on the old heating element. If you take a new radiator with similar performance and the same size, then the apartment will either be as warm as before, or even warmer.
If the battery is purchased for a new room, where you have to calculate the sections of bimetallic heating radiators from scratch by area, then one of the most important indicators that you should focus on is the size of the room. For central Russia, there are special standards for choosing heating radiators. There should be about 100 watts per 1 square meter. If we are talking about the northern regions, you should choose more powerful options.
Note! But keep in mind that calculating the battery solely by area may not be the best solution. Since errors are not excluded. They concern, first of all, those apartments, the sizes of which do not meet the standards. We are talking about those rooms where the height of the ceilings is more than 3 meters.
In addition, when choosing a radiator, you need to pay attention to the number of windows in the rooms and the degree of their insulation. If the apartment has location features, for example, it is a corner one, correction factors should be used when calculating the size of bimetallic heating radiators.
Please note that the heat output of the room decreases depending on the characteristics of the room.
To begin with, it is worth considering that each window in the room requires the addition of another 100 watts to the total. For the door, another 200 units are added. The correction factor for a corner apartment without wall insulation is 1.3.
In addition, there are special requirements when calculating indicators for different regions. For the Far North, for example, the correction factor is 1.6.
You also need to consider the location and method of installing the radiator. If it contains a decorative screen, and this option has recently become common, then this addition will "eat" about 1/4 of the heat from the battery. Installing a niche under the windowsill takes another 7%.
It is also worth considering that the calculation of power for an apartment and a private house will be different. The first housing option is considered warmer due to the presence of common walls with neighbors. For private houses there is an additional coefficient - 1.5. This addition is necessary in order to compensate for heat leakage through the cold attic and the uninsulated walls that are on each side of the house.
Scheme of heat loss of a private house
It should be noted that bimetallic radiators are rarely installed in private households. This is due to the high cost of the equipment. When a home owner wonders which is better, aluminum or bimetal, experts always recommend the latter option. They come in several types and differ in the way they are installed.
In both cases, several types of metal are used. Aluminum remains unchanged among them. In bimetallic radiators, only the upper part is aluminum, and the core itself is steel. The coolant is in contact exclusively with steel. This makes the battery powerful and durable, and also protects against corrosion. Bimetallic radiators are made in a figured case, which increases their heat transfer performance.
The device of a standard bimetallic radiator
In rare cases, you can find such batteries not with a steel core, but with a copper one. Basically, such batteries are used in heating systems with antifreeze. Steel pipes will not be able to withstand constant exposure to anti-freeze.
Bimetal radiators with copper pipes and cores are suitable not only for water, but also for overflowing oil and antifreeze
A distinctive feature of semi-bimetallic radiators is a specific core. In the process of its manufacture, two types of metal are used. Here, only vertical elements are made of steel, and horizontal pipes are made of aluminum. All this allows you to significantly increase heat transfer. Moreover, aluminum batteries are cheaper.
However, this version of the heater has several disadvantages. The main thing to note here is the rapid failure of the radiator elements. Here we are talking about situations where water with a high alkali content is used. Similar risks are relevant for apartments with central heating. Therefore, it is better to install aluminum semi-bimetallic radiators in private houses equipped with an autonomous heating system. Here the equipment will last a long time, and will not require constant repair or replacement.
It is especially important to choose the right radiators for apartments located in houses where the central heating system is under heavy load. The battery must be of high quality, capable of withstanding high water pressure, characterized by sudden drops.
The difference in heat transfer materials of heating radiators
Technical characteristics of bimetallic radiators can vary significantly. Therefore, it is important to clarify all the details that relate to the heating element before buying. Some time ago, only sectional batteries could be found on sale, but now the buyer has the opportunity to purchase monolithic products that have a number of advantages.
The fact is that the presence of separate sections in the battery involves joints. This is a weak point prone to corrosion. It is obvious that the service life of sectional radiators due to the presence of such a "bottleneck" is less than that of monolithic counterparts.
Monolithic bimetal radiators collect less dust and corrosion
The new technology allows you to create batteries from a solid steel or copper collector. A kind of aluminum case is put on top of it. Such radiators are called monolithic, and they are considered more durable, safer and more durable.
The average service life of monolithic products is 50 years, and sectional products - only 25. The operating pressure of a monolithic radiator can reach up to 100 bar, and for sectional batteries this figure is 3 times lower. The only characteristic that will be the same for each type of radiator is thermal power. It averages 100-200 watts.
Another distinguishing feature is the cost. Monolithic radiators last much longer, but they are also more expensive than sectional ones. Of the minuses of solid models, one can also highlight the inability to add or remove sections. Therefore, when buying such a bimetallic radiator, it is necessary to carefully select it in all respects, including size.
Among the leaders in the ranking of bimetallic heating radiators for an apartment are not only foreign companies, but also domestic manufacturers. But still, most buyers who are wondering which batteries are best for an apartment opt for European products. Batteries made in Italy are in great demand. Here it is worth mentioning the companies Syrah, Raden and Global Style. The cost of one section of batteries of these companies is at the level of 1000 rubles. The products are distinguished not only by their durability and high quality, but also by their elegant design and interesting finishes. The thermal power of 1 section is about 150 watts, and the maximum temperature that the Italian battery can withstand is 110 degrees.
