Hot water heat exchangers (boilers)
Horizontal hot water heat exchangers, also known as boilers, are cylindrical water tanks usually made of steel or stainless steel. They are insulated with polystyrene or polyurethane foam to minimise heat loss. In addition, the inside of the tank is enamelled to protect it from corrosion. Magnesium anode is also increasingly being used as an additional protection against corrosion. The heat exchangers have a capacity of up to 200 litres and are mounted in a hanging system. As a standard, the heat exchangers are equipped with a single coil adapted to receive heat from a single source. They are also available in a version with a double coil for solar sets or water jacket.
