PROBLEM TO BE SOLVED: To provide a storage type hot water supply device capable of bringing a bathtub closer to conditions of water temperature and water amount desired by a user while suppressing degradation of coefficient of performance of a heat pump unit. SOLUTION: This storage type hot water supply device 100 includes a water supply/hot water supply circuit 50, a bath water level sensor 61P, and a controller 10. The water supply/hot water supply circuit 50 adjusts a temperature of warm water in the hot water storage tank 35 and supplies the same to a bathtub 70. The controller 10 controls additional supply of hot water and additional supply of hot water of high temperature. In the control of additional hot water supply, a water level of the warm water in the bathtub 70 is increased by supplying the warm water to the bathtub 70 by the water supply/hot water supply circuit 50 in a case when the bath water level sensor 61P detects a value less than a supplied warm water determination value predetermined so that a value in an easy-to-radiate state is lower than a value in a hard-to-radiate state. In the control of additional hot water supply of high temperature, a temperature of the bathtub 70 is raised by supplying the warm water of a temperature higher than a set temperature to the bathtub 70 by the water supply/hot water supply circuit 50.
