It is recommended to choose bimetallic radiators.
Cast iron radiators remain the most common on the market. They are characterized by an affordable price and durability. However, their popularity is gradually declining due to the shift towards radiators with a higher heat output coefficient.
Aluminum radiators are considered the most efficient. Nevertheless, they have their drawbacks: brittleness and high chemical reactivity of aluminum, which negatively affects their lifespan. The best performance in central heating systems is demonstrated by bimetallic radiators, which are a combination of steel and aluminum.
Although they are slightly inferior in heat output due to the use of steel, bimetallic radiators lack the main disadvantages inherent in aluminum models.
