Abstract

PURPOSE: To stabilize the effluent hot water temperature by providing a first reference flow rate and a second reference flow rate to put a shut-off solenoid valve into open or close state, and setting the second reference flow rate lower than the first one.
CONSTITUTION: When the flow rate detected by a flow rate sensor 4 is higher than a first reference flow rate, a water solenoid valve 6 is opened to supply water into a water supply pipe 2, and the influent water is divided and supplied to water pipes 10 and 20. Then, as a flow switch 22 is closed and control circuits 50 and 60 are put into action, a combustion apparatus 40 start burning to heat up the influent water through heat exchangers 11 and 21, and the water from the heat exchangers joins into a hot water supply pipe 2a and flows out. When the water flow rate detected is less than the first reference flow rate and higher than the second reference flow rate that is lower than the first one, the water solenoid valve 6 is not closed. Therefore, as the combustion apparatuses 30 and 40 are operated in a steady state, the temperature of effluent hot water from the hot water supply pipe 2a can be stabilized.
