<p><P>PROBLEM TO BE SOLVED: To provide a hot water storage system which can secure an output of hot water at a setting temperature without lowering a hot water output temperature more than the setting temperature through cold auxiliary heat source equipment when hot water at the setting temperature can be supplied from the hot water storage tank side. <P>SOLUTION: Hot water in a hot water storage tank 14 having an inlet connected to a water supply path is heated by a heat collection device 21 utilizing solar heat and is stored, and the hot water in the hot water storage tank 14 and supplied water are mixed by a mixing valve 17 to supply a water input port of a hot water feeder 12 therewith. The hot water feeder 12 performs heating operations (additional heating) as needed so as to output hot water at the setting temperature. Even if hot water higher by a given temperature or higher than the setting temperature is stored in the hot water storage tank, when a heat exchanger of the hot water feeder 12 is in a state of getting cold, a control unit 60 controls a mixture ratio so that a temperature of water supplied to the water input port reaches a lower temperature by a given temperature or higher than the setting temperature so as to be heated by the hot water feeder 12. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
