Abstract:
PROBLEM TO BE SOLVED: To stabilize a hot water supply temperature in supplying hot water by sending hot water from a main heat source to an auxiliary heat source device.SOLUTION: A hot water supply heat exchanger and a bypass passage for sending hot water to a hot water supply side without passing through the hot water supply heat exchanger, are disposed on a hot water supply circuit of a water heater, and the hot water is allowed to pass through a hot water supply heat exchanger side and a bypass passage side within a bypass ratio change range. In starting a cold start hot water supply, hot water of a hot water supply set temperature is sent to a hot water supply circuit side of the water heater from the hot water storage tank side, and combustion control means 47 of the water heater starts combustion of a hot water supply burner, takes a detection temperature of a water supply temperature detection means 71 while supplying hot water by heating the hot water passing through the hot water supply circuit by the hot water supply heat exchanger, and continues hot water supply while stopping combustion of the hot water supply burner when the detection temperature becomes a value predetermined on the basis of a detection temperature of hot water heat exchange outlet-side temperature detection means 67 and a maximum value of a bypass ratio to a bypass passage side in the bypass ratio change range, and a water supply limit temperature or higher, lower than the hot water supply set temperature.SELECTED DRAWING: Figure 1
