PROBLEM TO BE SOLVED: To provide a bathtub temperature controller for lowering a hot water temperature to a set temperature while holding hot water in a bathtub at a constant level. SOLUTION: The bathtub temperature controller comprises a bath heater 10 for heating hot water 2 pumped by a pump 9, a temperature detecting means 3 for detecting a hot water temperature, a hot water temperature setting means 6, and a control means 4 for controlling the heater 10 in response to a hot water temperature regulation instructing signal from the means 5 and a detection temperature signal from the means 3. In this case, an auxiliary heat exchanger 12 provided in a circulation route 8 of the water 2 and a heat exchange medium supply means 14 for supplying low temperature heat exchange medium to the exchanger 12 are provided. The means 4, when an instructing signal for lowering the hot water temperature is inputted from the means 5, circulates the water 2 in the bathtub 1 by the pump 9, supplies the low temperature heat exchange medium from the means 14 to the exchanger 12, and cools the water 2 in the bathtub 1 in response to the detection signal from the means 3. |
