<P>PROBLEM TO BE SOLVED: To realize a mixing valve of a hot water storage type hot water supply device improving the operation efficiency of a heat source device by mounting the mixing valve for mixing the supplied hot water of two temperature zones and the tap water, on a hot water supply passage. <P>SOLUTION: This mixing valve of the hot water storage type hot water supply device comprises a hot water storage tank 12 for storing the hot water heated by the heat pump type heat source device 11, and the mixing valve 20 for mixing the supplied hot water in the hot water storage tank and the tap water to adjust a tapping temperature. In the mixing valve 20, the hot water of two temperature zones supplied from the hot water storage tank 12 and the tap water are allowed to flow, then two kinds of water are selected, and a mixing ratio of the selected two kinds of water is adjusted to flow the hot water of a desired tapping temperature. Whereby the operation efficiency of the heat pump type heat source device 11 can be improved. <P>COPYRIGHT: (C)2004,JPO |
