<P>PROBLEM TO BE SOLVED: To prevent degradation of heat efficiency of the entire hot water supply system by preventing mixing of high-temperature water and ordinary temperature water in hot water storage tanks. <P>SOLUTION: This hot water supply system 1 for storing the high-temperature water obtained by heating the ordinary temperature water by a heat pump 10 in the plurality of open-type hot water storage tanks 20, 30, and supplying the stored high-temperature water to a hot water supply port 70, comprises water meters 24, 34 for detecting the amount of high-temperature water stored in the hot water storage tanks 20, 30, a junction valve 54 for joining the high-temperature water supplied from the hot water storage tanks 20, 30 in a state that its opening corresponding to the hot water storage tanks 20, 30 can be controlled, and a control portion for controlling the opening corresponding to the hot water storage tanks 20, 30, of the junction valve 54, so that the high-temperature water stored in one of the hot water storage tanks 20, 30 can be used up on the basis of a result of the detection by the water meters 24, 34. <P>COPYRIGHT: (C)2009,JPO&INPIT |
