<P>PROBLEM TO BE SOLVED: To provide a hot water supply system capable of mixing hot water heated by solar energy and supplied hot water boiled up by using a heat pump cycle in a proper state. <P>SOLUTION: This hot water supply system comprises a solar energy water heater system 11 storing hot water by using solar energy collected by a solar energy collector 8, a heat pump water heater system 4 storing the supplied hot water boiled up by being circulated by the heat pump unit 1, and a hot water mixing system 20 for mixing the hot water stored in the solar energy water heater system 11 and the supplied hot water stored in the heat pump water heater system 4 and supplying the same. The hot water and the supplied hot water are mixed in the hot water mixing system 20 in a state that pressure difference is hardly found in piping. <P>COPYRIGHT: (C)2007,JPO&INPIT |
