Abstract:
To provide a water heater with a single can and two water channels, which enables water level detection operation during hot water supply operation.SOLUTION: A bath hot water supply device comprises a hot water supply heat exchanger that heats water supplied from a water supply passage and sends it to a hot water supply passage, a reheating heat exchanger that reheats circulating hot water circulating in a reheating circulation passage, and a water level sensor that detects the water level of hot water in a bathtub by water pressure, where a common burner is provided to heat the hot water supply heat exchanger and the reheating heat exchanger, and water level detection operation with the water level sensor is performed.
