PURPOSE:To provide a hot water supply bath apparatus wherein a reference water level is set properly. CONSTITUTION:A hot water supply apparatus is adapted such that hot water in a bath tank 12 is circulated to a bath heating heat exchanger 16 through heating circulation circuit 13 to additionally boil the hot water in the bath tank 12, and simultaneously the hot water in the hot water supply heat exchanger 1 is supplied to the bath tank 1 through the bath heating circulation circuit 13 to introduce the hot water into the bath tank 12. There are provided water level setting means provided in the bath heating circulation circuit 13, water level setting means 13 for setting the water level in the bath tank 12, and a control device for controlling the hot water supply to the bath tank by comparing a set water level set by the water level setting means and a detection water level detected by the water level detection means taking as a reference a certain position where the water level in the bath tank 12 is higher than a connection portion of the bath heating circulation circuit 13 and the bath tank 12. A specified flow rate more than a hot water amount with which a bath flowing water switch 19 is turned on is introduced and the water level at that time is taken as a reference to detect the water level. |
