ABSTRACT:
A very well heat insulated water storage or accumulator tank of relatively large capacity as compared to the capacity of the hot water heating unit is interposed between the unit and the radiator system and is interconnected with the unit. Heated water from the top portion of the tank is used to preheat the unit prior to actuation thereof, and mixed water above a given temperature is fed to the unit from the tank during actuation, such that the corrosive condensation on the heating surfaces of the heating unit, caused by heating a cold surface, is eliminated thereby extending the useful life of the unit. When the unit is actuated, heated water from the unit fills the tank from the top side until a volume of non-heated return water from the radiator system, approximately equal to the capacity of the unit, remains in the bottom of the tank. After the unit is deactuated, the non-heated water in the tank is utilized to cool the unit by replacing the heated water in the unit from the bottom side with cool water, causing the heated water in the unit to flow upwards into the tank. The different operations form together a "heating cycle", which is repeated again and again and which is performed entirely automatically by an electric control circuit. Energy is thus conserved because all of the heated water is utilized and the energy normally lost from a hot unit is significantly reduced. In this manner, the average efficiency of the system is greatly improved.
