PURPOSE:To obtain the hot-water heated at accurate presetting temperature by a simple constitution and operation by detecting the initial water temperature at the start of heating. CONSTITUTION:A hot-water temperature detecting means 11c is provided to detect the hot-water temperature with a thermistor 10. A heating time determining means 11b calculates the heating time with a microcomputer 15 based on the water storage quantity and detected temperature inputted from a water storage quantity inputting means 11a and a hot-water temperature detecting means 11c. A time setting means 11e presets the determined heating time, notifies the start and stop of heating to a heating control means 11d, the heating control means 11d controls a heating device 6 according to the information. |
