<P>PROBLEM TO BE SOLVED: To carry out operation with favorable energy efficiency in a hot water supply system. <P>SOLUTION: The hot water supply system is provided with a high temperature tank 3 storing high temperature hot water, a middle temperature tank 1 storing middle temperature hot water, and a selector valve 32 changing a delivery destination of heated hot water by a heat pump 2 to either one of the high temperature tank 3 or the middle temperature tank 1. A control part 4 changes the delivery destination to either one of the high temperature tank 3 or the middle temperature tank 1 in response to a temperature of boiled hot water. Since boiling of the high temperature hot water and the middle temperature hot water are carried out separately, operation with favorable energy efficiency can be carried out. <P>COPYRIGHT: (C)2008,JPO&INPIT |
