PROBLEM TO BE SOLVED: To provide a hot water storage type water heater capable of detecting such a state that a hot water supply valve is kept in an opened state, and preventing continuation of hot water supply from a hot water storage tank to a bathtub. SOLUTION: This hot water storage type water heater comprises a hot water storage tank 1 for storing hot water, a heat source machine for heating up the hot water in the hot water storage tank 1, a hot water supply pipe 9 for supplying water of high temperature from the hot water storage tank 1, a hot water/water mixing valve 13a for connecting the hot water supply pipe 9 and a water supply pipe 12 for supplying the water, a bathtub hot water supply pipe 24 for supplying the hot water/water mixed by the hot water/water mixing valve 13b to the bathtub, a bathtub hot water supply valve 25 for starting or stopping the supply of hot water/water to the bathtub 30, and a flow rate detecting means 26 for detecting a flow rate of the hot water/water supplied to the bathtub 30. When the flow rate detecting means 26 detects that the supply of hot water/water to the bathtub 30 is not stopped even though a signal for stopping the supply of hot water/water is output to the bathtub hot water supply valve 25, a start signal for starting the supply of hot water/water and a stop signal for stopping the supply of hot water/water are alternately repeatedly output to the bathtub hot water supply valve 25 by the predetermined number of times.
