摘要： A storage water heater capable of ensuring hot water supply temperature stability even if there is fluctuation in hot water supply-side flow rate is provided. The storage water heater includes: a hot water supply heat exchanger 52 for performing heat exchange between hot water in the hot water storage tank 8 and supply water; a hot water supply heat source conduit 46 that guides water from an upper portion of the hot water storage tank 8 to a lower portion of the hot water storage tank 8 via the hot water supply heat exchanger 52; a hot water supply heat source pump 48 that circulates water in the hot water supply heat source conduit 46, and a control section 36. In a hot water supply operation of heating supply water using a heat source that is the hot water in the hot water storage tank 8, the control section 36 performs PID control to calculate an output of a hot water supply heat source pump 48, the output bringing a heat source-side flow rate Fl, which is a flow rate of hot water flowing in the hot water supply heat source conduit 46, to a target flow rate Ftgt, for each control interval ΔTc. Here, the control section 36 sets the control interval ΔTc to be equal to the monitoring interval ΔTf when a hot water supply-side flow rate Fk is stable, and sets the control interval ΔTc to a control interval ΔTcmin, which is shorter than the monitoring interval ΔTf, when the hot water supply-side flow rate Fk rapidly fluctuates.
