すると、さらに安定性が良い。In the above embodiment, the water heater (1a) sets the rotation speed of the air supply fan (11) on the basis of the current supplied to the gas proportional valve (15). It may be a so-called fan precedent type in which the rotation speed of the air supply fan (11) is determined according to the rotation speed of the air supply fan (11) and the energization current to the gas proportional valve (15) is set based on the rotation speed of the air supply fan (11). . Similarly, hot water heater (2
Also in a), it may be a fan preceding type, in this case,
In order to prevent the combustion amount on the hot water heating side from changing depending on the number of revolutions of the air supply fan (11), it is sufficient to add a correction to the gas proportional valve (25) corresponding to the amount of change of the air supply fan (21). In this case, a rotation speed detecting means for detecting the rotation speed of the air supply fan (11) of the water heater (1a) is provided, and the air supply fan (21) on the side of the hot water heater (2a) is detected by the detected rotation speed. The stability is further improved by controlling the rotation speed of.
