For several decades, only two types of radiators, either cast-iron (most often, especially in residential buildings) or steel, welded from pipes, were used in the installation of heating systems. These two types of heaters have both advantages (relatively low cost) and disadvantages (large mass, low efficiency). Today there are many new developments that have technical characteristics and performance, far superior than those of the above, we can say already the "classic" heating devices. Moreover, in our time when calculating heating systems of the building are set at the head already completely different criteria.
If earlier, at a low fuel cost for boiler houses, heat transfer could and wasn’t put in the first place, since this parameter could be easily compensated by appropriate adjustment of heating system characteristics (by supplying network water with a higher temperature or increasing its flow rate). Now efficiency of heat energy transfer from network water to indoor air, one of the most important characteristics which are oriented when choosing a heating device. Also, at present, prices for construction and repair work are also rapidly increasing, and in order to reduce the cost of operating the premises, it is necessary that its engineering systems require maintenance as little as possible and retain their characteristics throughout their entire service life. The most suitable type for these criteria is a bimetallic radiator, despite the fact that it is a bit more expensive than other types of heaters.
A feature of the bimetallic radiator is that it is a compilation of steel and aluminum devices and combines the advantages of both types, but at the same time free from the inherent disadvantages of them. Moreover, such a successful complementary combination of materials, without significant drawbacks, is quite rare in the technique.
From the above picture, which shows both the finished element of the radiator (in the background) and its core, not yet encased in an aluminum shirt (in front), one can understand the design features of this type of equipment. They are a welded steel inner element and a massive body of light alloy. This design allows you to show the advantages of resistant to mechanical stress and corrosive effects of alloy steel and well-conductive heat and having a small specific mass alloy based on aluminum or magnesium. Needless to say, the process of producing this type of heating device is more complicated than just welding metal registers from pipes or casting iron or solid aluminum sections, but the advantages of bimetallic radiators strongly outweigh the higher labor intensity and cost, as will be seen in the following part of the review.
