Abstract

PURPOSE:To heat water automatically at a proper temperature by monitoring each differential value of a supply water temperature signal, a set temperature signal and a combustion quantity signal used for arithmetically operating combustion time and correcting the combustion time when the differential value exceeds a predetermined level. CONSTITUTION:In the titled device which heats water in a bathtub 2 by combustion gas by means of a burner 7 by a heat exchanger 8 mounted to a circulation pipe 9, a water supply control unit 18 is set up to a water cock 3. Each output signal of a supply water temperature sensor 42 and a water supply total amount signal generator containing a contactor 46 and a variable resistor 47 in the unit 18 is inputted to a controller 16 together with the temperature set signal and the combustion quantity signal by a remote controller 17, the combustion time of the burner 7 is arithmetically operated and a gas valve 21 is controlled. Each differential value of the supply water temperature signal, the set temperature signal and the combustion quantity signal is monitored, and the arithmetical value of said combustion time is corrected when the value exceeds the predetermined level.
