設けたものである。Problems to be Solved by the Invention However, in the above configuration, the combustion fan is operated at a constant speed, so when the supply temperature is low, such as in winter, the heat exchanger is excessively cooled, resulting in a poor feeling of cold water when hot water is re-discharged. In order to avoid the risk of freezing in the worst case scenario, a control means is provided to vary the speed of the combustion fan over time after the hot water supply operation is stopped.

The rotation speed of the combustion fan 8 up to time 0 is controlled according to the amount of combustion, and operates in a so-called air-fuel ratio control mode. When the faucet 4 is closed at time to, the running water switch 10 is turned off and the burner 5 is extinguished. Then, only the combustion fan 8 continues to operate until time t@. At this time, a timer is activated in the combustion fan control section in order to lower the rotational speed of the combustion fan 8 as time passes. Time t1, t2, and t3 are time t.
