<P>PROBLEM TO BE SOLVED: To provide a storage type hot water supply system capable of reducing the total energy consumption in the storage type hot water supply system including a heat pump unit and a burner unit. <P>SOLUTION: In this storage type hot water supply system, the heat pump unit 3 boils up the hot water/water in a hot water storage 11 to a target temperature TL higher than a starting temperature TS, when a temperature of the hot water/water in the hot water storage tank 11 is less than the starting temperature TS in a first time zone, the heat pump unit 3 boils up the hot water/water in the hot water storage tank 11 to a target temperature TH higher than the target temperature TL in starting a second time zone, and then the hot water/water in the hot water storage tank 11 is boiled up to the target temperature TH by the heat pump unit 3 when the temperature of the hot water/water in the hot water storage tank 11 becomes less than the starting temperature TS in the second time zone. <P>COPYRIGHT: (C)2010,JPO&INPIT |
