PURPOSE:To save labor required for controlling a heat source or the like by a method wherein the temperature of hot water within a hot water storage tank is detected at portions spaced with predetermined intervals from one another and the quantity of water and the amount of heat in a passage of heating cycle are controlled. CONSTITUTION:The hot water storage tank 1 in which a plurality of heat sensors 141 arranged in spaced apart relationships with one another and a heat exchanger 5 having a heat source 12 to be controlled by a heat input control device 13 are connected to each other through a transfer pipe 7 provided with a flow rate control device 10 and a hot water return pipe 9 having a hot water sensor therein, to thereby produce the passage A of heating cycle. With the above structure, the detecting signals fromthe sensors 141 and the detecting signal from the sensor 11 are inputted into a program control circuit 3 and the heat input control device 13 and the flow rate control device 10 are controlled in response to a predetermined hot water supply timing and a predetermined quantity of hot water so that a predetermined hot water temperature is automatically obtained. |
