PROBLEM TO BE SOLVED: To provide a hot water supply device 1 having a new function regarding control of a bathtub water level by utilizing a pressure sensor 150 capable of detecting a water level to a bottom of a bathtub 7.SOLUTION: A hot water supply device 1 for performing hot water filling by detecting a water level in a bathtub 7 comprises: a pressure sensor (water level sensor) 150 for detecting the pressure of water at a bottom part of the bathtub 7; a drain plug 12 for discharging and stopping water in the bathtub 7; and a driving device 13 for opening/closing the drain plug 12 by a control signal. On the basis of water level information from the pressure detection means 150, the driving device 13 controls an open/closed state of the drain plug 12. A control device 100 in a hot water storage tank part 2 transmits a control signal and executes the control of one of: confirmation of unplugging of the drain plug 12; drain completion notification to a remote control 15; automatic hot water filling after draining the water of the bathtub 7; simple washing of the bathtub 7; and assisting drainage at the time of bathtub 7 washing. |
