<P>PROBLEM TO BE SOLVED: To provide hot water in an intermediate-temperature layer with a hot water temperature capable of being used in mixed hot water supply without changing a boiled temperature of the hot water of intermediate-temperature layer by a user every time when a mixed hot water supply temperature is changed, in a hot water storage type hot water supply system for supplying the mixed hot water by mixing the hot water of a high temperature layer or the intermediate-temperature layer in the hot water storage tank with the supplied water. <P>SOLUTION: In this hot water storage type hot water supply system 10, hot water is boiled up by a heat source machine 13, stored in the hot water storage tank 11 in a state that the high temperature layer and the intermediate-temperature layer coexist, and mixed with the supplied water to supply the mixed hot water. A control portion 14 controls the boiling-up of hot water by the heat source machine 13 on the basis of a hot water temperature detected by a hot water temperature sensor 15, and sets the boiling-up temperature of the hot water of intermediate-temperature layer according to the mixed hot water supply set temperature input by an input portion 18. Thus the boiling-up temperature of the hot water of intermediate-temperature layer is automatically set so that the hot water of intermediate-temperature layer has the hot water temperature capable of being used in the mixed hot water supply, lowering of utilization of the hot water of intermediate-temperature layer can be prevented, and energy efficiency in the mixed hot water supply can be improved. <P>COPYRIGHT: (C)2009,JPO&INPIT |
