<p><P>PROBLEM TO BE SOLVED: To provide an easy-to-construct hot water supply system with an instantaneous hot water supply function, having a small number of components and excellent durability. <P>SOLUTION: In hot water supply operation, hot water supplied from a hot water supply apparatus 2 through a hot water supply pipe 5 and clod water supplied from a water source through a cold water supply pipe 6 are mixed into a set temperature in a hot-water/water mixing valve 15 and are supplied to a hot water supply faucet 3. In heat-retaining operation, a temperature of the hot water inside the hot water supply pipe 5 is detected by a temperature detection sensor 16a. When the detection temperature drops to a prescribed lower limit temperature, an opening/closing means 18 is opened to supply the hot water inside the pipes to a bath 4, and operation of the hot water supply apparatus 2 is started. When the detection temperature increases to a prescribed upper limit temperature, the opening/closing means 18 is closed, and the operation of the hot water supply apparatus 2 is stopped. <P>COPYRIGHT: (C)2004,JPO</p> |
