Rating of bimetal radiators for apartments and houses

Bimetal batteries are the most modern radiators among the existing ones. They are easily installed, allow you to get a lot of heat, and look attractive, in addition, not able to spoil the interior design. However, in stores today different radiators are realized, which differ in their technical and design characteristics. Which of them is better to choose, you can find out if you are familiar with the rating of the manufacturers and features.

The difference between a semi-bimetal and a bimetal

Today the best bimetallic heating radiators of proven manufacturers are manufactured using different technologies. If it is a question of metal, in such devices aluminum becomes a material for an external part. Pipes of a steel core in the manufacturing process are welded, and then subjected to pressure and filled with aluminum. As a result, water contacts only with steel, but it does not touch the aluminum surface. This saves products from corrosion and gives them a quality of increased reliability. The figure case increases the heat output.

On sale you can find radiators with a copper core, this option is a rescue for autonomous heating systems, where water is supplemented with antifreeze. This is due to the fact that the steel pipes quickly fail, if such a composition will flow through them. You can buy the best bimetal radiators. According to experts, among them one can find semi-bimetallic ones, the core of which has two metals. Vertical channels are fixed with steel elements. The amount of aluminum increases, which increases the heat transfer. But hot water, which contains alkali, will be in 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 the core to shift, which leads to unstable battery operation.

Solution of the problem of central heating

The rating of bimetal 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 - high pressure, the other - poor-quality coolant. Two of these factors have a negative effect on the radiators of the semi-bimetallic type. Therefore, if you want to use reliable heating devices, then it is best to give preference to bimetallic ones, since semi-bimetallic ones have a higher cost. The best semi-bimetal radiators can be found in the following companies: Sira, Gordi, and also Rifar.

Monolithic or sectional bimetal devices

Bimetallic heating radiators, whose rating by manufacturers will be listed below, can be monolithic or sectional. Previously, similar products were assembled from several sections, but they suffered from a coolant that damaged the joints and greatly shortened the life of the device. Joints are a dangerous place, which is most prone to leakage due to increased pressure. Therefore, radiators were invented, which provide for the presence of a copper or solid steel collector. On top of it is put on a shirt made of aluminum, such devices are called monolithic.

Considering the rating of the best bimetal radiators, you will see batteries that are monolithic and sectional. The first have advantages over the term of operation, they can be used for 50 years, while the sectional ones will last about 25 years. The working pressure of the first can reach 100 bar. For one section, the thermal power of monolithic devices is about 200 watts, as for sectional models, they are on the same level with their competitors in this matter. However, cost monolithic devices are more expensive, the difference can be up to 1/5. As another nuance it can be noted that models with a single core can not be modified, adding or removing sections can not be done in different sizes in length and height. Therefore, it will not be difficult to find a battery.

For reference

The rating of bimetal radiators includes monolithic and sectional models. If your apartment is in a multi-storey building, whose height exceeds 16 floors, the pressure of the coolant will be impressive. Therefore, there is a need to give preference to monolithic models in this case.

Rating by manufacturer: Italy

The rating of manufacturers of bimetallic radiators includes plants that are located in Italy. First of all, we should highlight Sira, whose specialists invented bimetal radiators. No less popular in the market for such products are the Global Style brands, as well as Radena, whose products in one section have a cost ranging from 700 to 1500 rubles.

Features of bimetallic radiators of the brand RADENA

If you are interested in the rating of bimetal radiators, then it will be fair to consider the features of RADENA batteries, which, according to the manufacturer, are devices of increased strength. Radiators have several separate sections, each of which are connected to each other by means of paronit cushions and steel nipples. The inner part is a tubular frame made of carbon steel, which guarantees durability. This part acts as a channel for the flow of the coolant. The frame of the section is made of steel pipes, which completely exclude water contact with the aluminum shell. The producer managed to achieve the absence of conditions for electrochemical corrosion.

Russian bimetal radiators

Considering the rating of bimetal radiators for home, we can not but mention Russian products. One of the most famous is the firm Rifar. It is located in the Orenburg region and produces appliances, the price of which varies from 500 to 900 rubles per section. The thermal power can vary from 100 to 200 watts, the working pressure does not exceed 20 bar. The temperature of the circulating hot water can reach 135 ° C. If you are interested in patented radiators, you can consider the company RIFAR MONOLIT, which is often called the consumers of the company, which produces some of the best instruments of the domestic market. They are able to withstand pressures up to 150 bar, and the 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.

Information about bimetallic radiators of brand Forza

These devices are popular for installation in central heating systems. In them, the manufacturer took into account the requirements and peculiarities of operation of domestic heating systems. On sale you can meet models with a center distance of 200 and 350 mm, this allows you to withstand the style in rooms with different restrictions on the height at the points of installation. A feature of these radiators is a closed rear surface, which allows the use of a radiator in combination with French windows.
