Heating boilers with cast iron heat exchanger

Cast iron

— boilers with a cast iron heat exchanger heat up for a long time and cool down slowly, retaining heat for a long time after heating stops. Cast iron is also notable for its high heat capacity and low susceptibility to corrosion. The service life of a cast iron unit can be 30 or 50 years. The reverse side of the coin is the huge weight and size of heating equipment, which is why boilers with cast iron heat exchangers are mainly floor-standing units. In addition, cast iron does not tolerate sudden temperature changes — they can cause cracks.
