<p><P>PROBLEM TO BE SOLVED: To provide a hot water supply system capable of supplying hot water at a stable temperature during re-supplying hot water. <P>SOLUTION: This hot water supply system is provided with a supply water temperature sensor 11 for detecting a temperature of water passing through a water supply pipe 1, a supply hot water temperature sensor 9 for detecting a temperature of hot water passing through a hot water supply pipe 10, an electric hot and cold water mixture valve 8 for mixing the water from the water supply pipe 1 and the hot water from the hot water supply pipe 10, a flow rate sensor 13 for detecting flow of the mixed hot water passing through a mixed hot water supply pipe 12 supplying the mixed hot water from the electric hot and cold water mixing valve 8, a mixed hot water temperature sensor 14 for detecting a temperature of the mixed hot water passing through the mixed hot water supply pipe 12, a control part 15, and a remote controller 16 for setting the supply hot water temperature, wherein the control part 15 stores an opening degree of the electric hot and cold water mixture valve 8 as a stable opening degree when a set value of the supply hot water temperature set by the remote controller 16 and a detection value of the mixed hot water temperature sensor 14 are equal during detecting of supply of the mixed hot water by the flow rate sensor 13, and controls so that hot water supply is started from the stable opening in the next start of hot water supply. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
