Radiators are the main link in the heating system. It is necessary to approach the choice with a maximum responsibility, since the life of their operation lasts up to 35 years. Cast iron or bimetallic? It is important to find the right answer to this question. Cast iron has already proven themselves in the market, but today competition is more elegant, modern bimetallic heating radiators. By choosing a heating radiator for a home, consider: durability, reliability, heat transfer, cost and design.
1
The bimetallic radiator consists of a steel frame with aluminum. The name of the radiator speaks of the use of two types of material - the body of aluminum, inside - steel pipes. Aluminum provides better heat transfer, i.e. Rapid heating and heat transfer of the atmosphere around, and steel pipes are not oxidized as aluminum, and have good anti-corrosion properties. Cast-iron heat transfer radiators are lower, they are slower than and cool, approximately 6 hours. If the air temperature rose on the street, the bimetallic radiators are easy to turn off using an adjusting valve and create a comfortable atmosphere in the apartment.

Made a comparison of radiators heat transfer, now consider reliability and durability. Radiators have a service life of about 20-25 years of operation. Of course, in the first place in terms of reliability there are cast-iron batteries, the impeccability of their service is tested by time. They are resistant to corrosion and poor coolant, but roughness inside contribute to the formation of a limescale, detention of impurities contained in a poor-quality coolant. Bimetallic radiators have high wear resistance and durability due to high-quality aluminum alloy, a solid connection of individual sections.

Another important factor is resistance to hydraulic impact. Bimetal is able to withstand the pressure reaching 40 atmospheres. The working pressure of pig-iron radiators is 12 atmospheres, bimetallic - 20 atmospheres. Such radiators result in longer, they are more adapted to centralized heating, hydraulic and mechanical shocks, to the coolant is not very high quality. Companies engaged in the production of radiators from Bimetal, give a guarantee of 20 years to their products. In a country house with individual heating, the pressure is about 2 atmospheres, therefore the resistance of the radiator to the hydraulic man is less important.

Cast iron radiators are more cumbersome, it is difficult to paint and wash, and bimetallic - do not need painting. Powder paint covering radiators makes them very resistant to mechanical effects, radiators are easily clean, without the use of detergents. Externally, bimetallic and aluminum radiators are very similar, but differ easily by weight. Bimetallic - heavier, weight difference reaches 60%. As for the aesthetics of bimetallic radiators, then the case of the buyer's taste. Externally, radiators are distinguished by their design and color of the coating. Most used snow white (Sira and Rifar) and cream color (Global).

It is also important and the last factor when choosing a heating radiator - the price of the product. The cheapest is aluminum, then cast iron and bimetallic. Installation of bimetallic radiators is completely simple, iron is much more complicated. The cost of one section of pig-iron radiators varies in the range of 300-2000 rubles. Last price - for art casting. Bimetallic - stand in one section of about 350 to 800 rubles. Those who cost cheaper, no worse than more expensive, but they have less spent on them, they look more modest outwardly, the design is easier. This does not reflect this, because The entire range is subject to certification. They can not cost cheaply, but their undoubted advantages will pay off your costs.
Above expensive and some special, ultra-home bimetallic models on the market there are practically no. There is only differences in models with a non-standard intercentrons: excess of narrow models (200 mm), there are large models (800 mm) and not straight, but rounded models for rounded rooms. The middle interconnect distance is 350 and 500 mm.
