Bimetallic batteries are the most modern radiators among the existing ones. They are mounted without problems, they allow you to get a lot of heat, and they look attractive, in addition, they are not able to spoil the interior design. However, today various radiators are being sold in stores, which differ in technical and structural characteristics. Which of them is better to choose, you can find out if you familiarize yourself with the rating by manufacturers and features.
The difference between semimetal and bimetal
Today, the best bimetal heating radiators from trusted manufacturers are manufactured using different technologies. When it comes to metal, in such devices, aluminum becomes the material for the outer part. The steel core pipes are welded during the manufacturing process, and then they are subjected to pressure and filled with aluminum. As a result, water only contacts steel, but it does not touch the aluminum surface. This saves products from corrosion and gives them high quality reliability. The figured body improves the heat transfer.
On sale you can find radiators with a copper core, this option is a salvation for autonomous heating systems, where water is supplemented with antifreeze. This is due to the fact that steel pipes will quickly fail if such a composition flows through them. You can get the best bimetal heating radiators. According to experts, among them can be found semi-metallic, their core has two metals. Vertical channels are fixed with steel elements. The amount of aluminum increases, which improves heat transfer. But hot water, which contains alkali, will come into contact with aluminum, which will lead to the beginning of the corrosion process. Steel parts and aluminum elements have different thermal expansion, this can cause core displacement, which leads to unstable battery operation.
Solving the problem of central heating
The rating of bimetal heating radiators contains appliances that can be installed in an apartment with a central heating system. Her work is accompanied by two problems, one of them is high pressure, the other is a poor-quality coolant. These two factors have a negative effect on semi-metal type radiators. Therefore, if you want to use reliable heating devices, it is best to give preference to bimetallic, since semi-bimetallic are of higher cost. The best semi-metal radiators can be found at the following companies: Sira, Gordi, as well as Rifar.
Monolithic or sectional bimetallic devices
Bimetal heating radiators, the rating of which by manufacturers will be indicated below, can be monolithic or sectional. Previously, similar products were assembled from several sections, but they suffered from a coolant that damaged joints and significantly reduced the life of the device. Joints are a dangerous place that is most susceptible to leakage due to high pressure. Therefore, radiators were invented, which provide for the presence of a copper or solid steel manifold. An aluminum shirt is put on top of it; such devices are called monolithic.
Considering the rating of the best bimetal heating radiators, you will see batteries that are monolithic and sectional. The former have advantages in terms of working life, they can be used for 50 years, while sectional ones will last about 25 years. The working pressure of the first can reach 100 bar. In one section, the thermal power of monolithic devices is approximately 200 watts, as for sectional models, they are on this level with their competitors. However, the cost of monolithic devices is more expensive, the difference can be up to 1/5. As another nuance, we can highlight the fact that models with a solid core cannot be modified, sections cannot be added or removed, they are made in different sizes in length and height. Therefore, picking up a battery is not difficult.
For reference
The rating of bimetal heating radiators includes monolithic and sectional models. If your apartment is located in a multi-storey building, the height of which exceeds 16 floors, then the coolant pressure will be impressive. Therefore, there is a need to give preference to monolithic models in this case.
Rating by manufacturers: Italy
The rating of manufacturers of bimetallic radiators includes factories located in Italy. First of all, it is worth highlighting the Sira company, whose specialists invented bimetallic radiators. Equally popular on the market for such products are Global Style brands, as well as Radena, whose products for one section have a cost in the range from 700 to 1500 rubles. These devices have high-quality elegant finish, attractive appearance, low weight and compactness.

Features of bimetallic radiators of the RADENA brand
If you are interested in the rating of bimetal heating radiators, then it is fair to consider the features of RADENA batteries, which, according to the manufacturer, are ruggedized devices. Radiators have several separate sections, each of which is connected to each other using paronite gaskets and steel nipples. The inside is a carbon steel tube frame that guarantees durability. This part acts as a channel for the flow of coolant. The frame of the section is made of steel pipes, which completely exclude contact of water with an aluminum shell. The manufacturer managed to achieve a lack of conditions for electrochemical corrosion.
Russian bimetal radiators
Considering the rating of bimetallic heating radiators for the home, one cannot but mention Russian goods. One of the most famous is the company Rifar. It is located in the Orenburg region and makes devices, the price of which for one section varies from 500 to 900 rubles. Thermal power can vary from 100 to 200 watts, operating 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 the company RIFAR MONOLIT, which is often called by consumers a company that produces some of the best appliances in the domestic market. They are able to withstand pressure up to 150 bar, and sectional heat output varies from 134 to 196 watts. The operating pressure can reach 100 bar, and the hot water temperature limit is 135 ° C.

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 the installation points. A feature of these radiators is a closed rear surface, which allows the use of a radiator in combination with French windows. The heat carrier 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 uninterrupted operation for 15 years. In this case, it is necessary to observe the rules of operation, transportation and installation.
Other countries
Before purchasing the described devices, you can consider the rating of bimetal 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 limit of hot temperature is 130 ° C. Sectional heat transfer is 167 watts, with regard to working pressure, then it can reach a maximum of 20 bar.
The Japanese company REGULUS-system, which manufactures radiators with a copper core, will be fair. By purchasing this product, you can count on a 25-year warranty. The operating 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 products of well-known brands, however they have an attractive design and good finish. With a modest budget, you can buy radiators from a Chinese manufacturer, however, as practice shows, they are able to undergo less impressive pressure.
