<p><P>PROBLEM TO BE SOLVED: To provide a hot-water supply cogeneration device capable of reducing the running cost and reducing the equipment capacity by using a combustion- type generator in combination with a hot water storage-type electric water heater. <P>SOLUTION: A hot water storage operation control means in a control panel 5 inputs a temperature Th1 of the hot water in a surge tank 11, a temperature Th3 of the hot water supplied to a heat exchanger 7 from the surge tank 11, a maximum temperature Th2 of the hot water in a hot water storage tank 29, and a water storage amount W in the surge tank 11, and outputs the operation command OC, the heat exchanging switching command RC and a water supply command WC in accordance with the predetermined operation control mode. The hot water storage operation control means creates the operation control mode to use the hot water in the surge tank 11 as a hot-water supply source, prior to the hot water in the hot water storage tank 29 in the hot water storage-type electric water heater 31. <P>COPYRIGHT: (C)2004,JPO</p> |
