Abstract

PURPOSE: To prevent afterboiling and the like in a gas-fired water heater in which the hot-water supply amount is regulated by regulating the air supply amount and controlling the gas supply amount according to the air supply amount, by making it possible to apply a D.C. component to the motor, for driving the fan in order to damp said motor.
CONSTITUTION: When the gas-fired water heater is used, a flow switch 9 is turned on by making hot water flow out and a deviation signal between the detected temperature and the setting temperature is outputted from an amplifier 21. Thereby, the phase of the trigger signal to a triac 43 is controlled by a phase controlling circuit 41 in a fan driving unit through a trigger circuit 42: when the detected temperature is lower than the setting temperature the energizing angle is made larger so that the increase in the number of revolutions of a motor 45 causes the air supply amount to increase; when the detected temperature exceeds the setting temperature the supply of the trigger signal to the triac 43 is stopped and changed over to the supply of the trigger signal to an SCR47. Accordingly, the SCR47 is turned on, so that a D.C. voltage of a D.C. power source 46 is applied to the motor 45 to be damped.
