Patent ID: 8413615

Claim:
A hot water supply apparatus comprising: a hot-water supply pipe for guiding hot water generated by a hot-water generator to a hot-water supplying terminal; two hot-water supply temperature sensors for detecting water temperature in the hot-water supply pipe; a temperature control unit for adjusting a temperature of hot water supplied to the hot-water supplying terminal; a sensor abnormality determining unit for determining sensor abnormality of temperature detection accuracy when a different between temperatures detected by the two hot-water supply temperature sensors is larger than a predetermined permissible error; a sensor selector for selectively setting one hot-water supply temperature sensor detecting a higher temperature as a hot-water supply temperature sensor for temperature control when the sensor abnormality is determined by the sensor abnormality determining unit; and a hot-water supply temperature controller for controlling the temperature control unit so that a temperature detected by the hot-water supply temperature sensor for temperature control selected form the two hot-water temperature sensors is matched with a set temperature.
