Document Type and Number:
Japanese Patent JP6863724
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a hot water supply system in which a hot water supply temperature is not significantly lowered in restarting hot water supply within a fixed time after stop of hot water supply.SOLUTION: A water heater 10 includes a first combustion chamber 13a accommodating a first heat exchanger 15 for hot water supply and a first burner 14a, a second combustion chamber 13b accommodating a second heat exchanger 16 for an air heating circuit and a second burner 14b, and a combustion fan 11 operated in combustion of at least one of the first and second burners 14a 14b to send air to both of the first and second combustion chambers 13a, 13b. A heat radiation device 70 receives information indicating an operating state of hot water supply motion from the water heater 10, and stops transmission of an operation request for air heating operation for a prescribed time after termination of use of supply hot water. As combustion of both of the first burners 14a and the second burners 14b is stopped after stop of hot water supply, and the combustion fan 11 is stopped, lowering of a temperature of the first heat exchanger 15 by the air blown from the combustion fan 11 is suppressed.SELECTED DRAWING: Figure 1
