PURPOSE:To constantly perform a safe hot water supply without abruptly supplying high-temperature hot water by such a construction that a control part selects one hot water temperature switching part from a remote controller, and has a hot water temperature selecting part which draws the hot water temperature gradually near to the set temperature of a newly selected hot water temperature setting part, when the output signal of the water temperature switching part changes. CONSTITUTION:Remote controllers 12 and 13 provided in correspondence with water plugs 14 and 15 are provided with hot water temperature setting parts 16 and 17 which set the water supply temperature. A changeover switch 18 which selects the temperature setting in priority is provided in the remote controller 13. The control part 19 provided with a microcomputer controlling the hot water supply part by output signals from the remote controllers 12 and 13 comprises respective function realizing means such as set temperature inputting means, set temperature selecting means, temperature gradually increasing means, and heating control means. By this organization, abrupt supply of high-temperature hot water of a temperature higher than the set temperature can be prevented by the change in the hot water temperature in priority by a changeover switch 18, and the user of hot water is informed beforehand of the change in the temperature of hot water, and hence can be supplied with hot water constantly and safely. |
