The best manufacturers of bimetal heating radiators and an overview of their lineup
Bimetal radiators made of steel and aluminum fully comply with modern requirements and do not need additional advertising. If you do not know which company it is better to purchase a bimetallic heating radiator for an apartment or office, then this article will help you in solving this problem.
The selection of goods was carried out on the basis of reviews, opinions and ratings of users posted on various resources on the Internet. All information is taken from public sources. We do not cooperate with manufacturers and trademarks and do not call for the purchase of certain products. The article is for informational purposes only.
What you need to know about the types of bimetal heating radiators
Aluminum is an excellent structural material characterized by strength, lightness and high thermal conductivity. It would be ideally suited for the manufacture of heat transfer equipment if it were not so sensitive to the quality of the coolant. Its structure is violated when deviating from neutral values of the coolant acidity index.
Electrochemical corrosion processes that occur upon contact with shutoff valves based on copper alloys also have a destructive effect on it. In addition, aluminum can not withstand water shocks present in centralized heating systems.
The creators of bimetallic radiators were able to eliminate these problems. The design of such products involves contact with the coolant only steel parts that are externally covered with a layer of aluminum fins. As a result, the corrosion rate sharply decreased, and heat transfer improved.
Bimetal and semi-metal radiators
All components of bimetallic radiators are usually made of high-quality steel, followed by surfacing under high pressure aluminum. After assembling the radiator, only the steel parts of all parts come into contact with the coolant, and the aluminum fins - with the room air.
Due to the special shape of the outer surface, intense heat transfer occurs, which is what is required from a good radiator.

Sometimes the core of radiators is made of copper alloys. In this case, they can be used in systems filled with antifreeze. The cost of such products is higher.
Semimetal radiators are distinguished by the fact that only vertical channels are made of two metals, and horizontal remain aluminum. The result is a small gain in heat transfer power, but there are also serious drawbacks:
- increased risk of alkaline corrosion;
- the difference in the specific thermal expansion of steel and aluminum leads to a displacement of parts, which can lead to depressurization of joints;
- this design proved to be susceptible to destruction by hydraulic shocks, which often occur in centralized heating systems.
Therefore, semi-metallic heating appliances should be purchased with great care, it is better not to use them in apartments with a centralized heating system.
Sectional and monolithic bimetallic radiators
Initially, all bimetallic radiators were sectional. They were assembled from several identical sections, tightly connected into a single unit.In some cases, the presence of joints between sections can lead to a decrease in the life of the radiator. During operation, moisture can get into the joints, irreversible processes begin, leading to corrosion and depressurization.
Sectional bimetal heating radiator.
Currently, some manufacturers produce monolithic bimetallic radiators. In such radiators, a solid steel base is created, which is covered on the outside with an aluminum shell.
Monolithic bimetallic radiators have significant advantages:
- service life doubled and reached 50 years;
- an opportunity to create radiators capable of withstanding an internal pressure of 100 atmospheres;
- sharply reduced the risk of factory defects.
The specific thermal power of the sections remained at the same level of 100-200 watts. Due to more complex production, monolithic batteries are 10-20% more expensive than section batteries. They can’t be removed or added with additional elements, so manufacturers produce a wide range of models that differ in size and thermal performance.
