PROBLEM TO BE SOLVED: To provide a hot water supplier with which the sensitivity degradation of a bath thermistor for detecting the temperature of water in a bathtub can be detected when additionally heating the water in the bathtub. SOLUTION: Concerning a hot water supplier 1 which is provided with feeding hot water thermistor 6 for detecting the temperature of hot water at the time of hot water supply and a bath thermistor 7 for detecting the temperature of water in the bathtub and supplies hot water passed through the feeding hot water thermistor 6 and the bathtub thermistor 7 into the bathtub at the time of feeding hot water, when the difference between the temperature detected by the feeding hot water thermistor 6 and the temperature detected by the bath thermistor 7 is not settled within the prescribed temperature range after the lapse of prescribed time from the start of hot water feeding, the defect of the bath thermistor 7 is judged. |
