The boiler is a tank where water is stored for heating integration and hot water systems use.
Sunerg boilers are suitable to meet different requests. In a natural circulation system, the boiler is situated in an higher than the solar collector and through a natural process of convection the liquid, heated by the sun, expands and reaches the heat exchanger inside the tank. Here the heat is released to water. In a forced circulation system, however, the boiler is placed inside the house. Fluid circulation and heat transfer happens by the help of a circulation unit.
