御装置。 A heat exchanger, a water amount detection means for detecting the flow rate of a waterway connected to the heat exchanger, a temperature detection means for detecting a temperature difference between the inlet water temperature and the outlet water temperature of the heat exchanger, and a combustor that heats the heat exchanger. , a proportional valve provided in a gas path connected to the combustor, a blower fan that supplies combustion air to the combustor, and a proportional valve that detects that the proportional valve has reached its maximum opening, and detects the temperature detecting means and the water amount detecting means. Determine the actual output of the combustor based on the detection signal from the signal, compare this actual output with the specified output, and when the proportional valve reaches its maximum opening, the actual output is lower than the specified output for a predetermined period of time. A blower fan control device for a water heater, comprising: a controller that increases the fan rotation speed of the blower fan if the blower fan is larger.
