PURPOSE:To make a titled device not to overflow even if water is fed after supply of hot water, by so constituting that supply of hot water whose quantity is equivalent to a given calorific value is made to a bathtub even if a feed hot water temperature is high or varied from high to low in the course of its supply. CONSTITUTION:A heating quantity is controlled by a deflection signal between a given temperature of a temperature setting device 118 and a feed hot water temperature detected by a temperature detector 134. A calorific value detector 145 for feed hot water is constituted with a flow detector 136, a calorific value arithmetic unit 148 calculating a calorific value by signals of the flow detector 136 and the temperature detector, an integration calorific value arithmetic unit 149 integrating the calculating calorific value and an integrating flow arithmetic unit 147 calculating an integrating flow by a signal of the flow detector. In addition to the above, a calorific value setting device 146 for feed hot water is constituted with a temperature setting device, an integrating flow setting device 123 setting up a feed hot water quantity and a calorific value arithmetic unit 150 calculating a calorific value by signals of both the setting devices. A flow controller 144 is controlled in an opening and closing state by a deflection between signals of the calorific value detector 145 for feed hot water and the calorific value setting device 146 for feed hot water. |
