PURPOSE:To obtain high-temperature hot water all the time by varying the capacity of a heat storage tank according to the amounts of heat collected by a method in which an expandible air tank is provided in a heat storage tank, an air supplyer and an air vent valve are connected, and a control circuit to detect the upper temperature of the heat storage tank and also to control the air supplyer and the air vent valve is provided. CONSTITUTION:An expandible air tank 12 is provided in a heat storage tank 1 and connected to an air supplyer 13 using compressor, etc., and an air vent valve 14. by a temperature sensor 8 and a controller circuit 15 provided on the upper part of the tank 1, when the temperature of the tank 1 is low, the capacity of the tank 1 is minimized by sufficiently expanding the air tank 12 by the air supplyer 13. As the temperature rises, the vent valve 14 is operated to slowly discharge air from the tank 12, and the capacity of the tank 1 is gradually increased. By controlling the vent valve in a finely divided staged manner, the capacity of the tank 1 can be always regulated to meet the amount of heat collected and high-temperature hot water can always be obtained. |
