PURPOSE:To conduct water supply and heating for a bath automatically, and to economize water and fuel by arithmetically operating combustion time from a set temperature signal, a combustion quantity signal, a water supply total amount signal and a supply water temperature signal from a water supply control unit and controlling a gas valve. 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 remote controller 17 is set up at the bathroom B side while the water supply control unit 18 is attached to a water cock 3. The water supply control unit 18 is provided with a supply water temperature sensor 42, a water supply total amount signal generator containing a contactor 46 and a variable resistor 47 and a supply water quantity detecting mechanism containing a water wheel 49 turned when water is supplied and a reduction gear group 50. The combustion time is arithmetically operated by means of a controller 16 from the water supply total amount signal and the supply water temperature signal from the unit 18 and the temperature signal and the set combustion quantity signal from the controller 17, and the gas valve 21 is controlled in accordance with the arithmetical value. |
