<P>PROBLEM TO BE SOLVED: To provide a hot water supply system capable of accurately performing mixing temperature adjustment control even immediately after switching from hot water filling operation to general hot water supply operation in which a bypass valve is opened. <P>SOLUTION: The hot water supply system includes control means 20, 50. When the bypass valve 38 is opened, the control means 20, 50 perform first mixing temperature adjustment control for adjusting temperature of hot water by mixing hot water of a hot water storage tank 31 and water of a water supply pipe 1 based on temperature detected by a hot water supply outlet temperature sensor 39. When the bypass valve 38 is closed, the control means 20, 50 perform second mixing temperature adjustment control for adjusting the temperature of hot water by mixing the hot water of the hot water storage tank 31 and the water of the water supply pipe 1 based on temperature detected by a mixing temperature sensor 36. When the hot water filling operation is switched to the general hot water supply operation, the control means 20, 50 switches the second mixing temperature adjustment control to the first mixing temperature adjustment control through a predetermined delay time including at least a time needed for fully opening the bypass valve 38 from the fully-closed state. <P>COPYRIGHT: (C)2011,JPO&INPIT |
