  • Hot water supply apparatus
    Patent number: 8413615
    Abstract: A hot water supply apparatus including: 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 the hot water supplied to the hot-water supplying terminal; a sensor abnormality determining unit for determining sensor abnormality when a difference 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; 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 from the two hot-water supply temperature sensors i
