PROBLEM TO BE SOLVED: To provide a bath device with a water heater which determines whether it is occurrence of clogging abnormality or occurrence of abnormality in second water level detection means.SOLUTION: A bath device with a water heater includes: a neutralizer 33 including a first water level sensor 35 for detecting that a drain water level has reached a first predetermined value; a drain tank 37 including a second water level sensor 38 for detecting that the water level of the neutralized drain has reached a second predetermined value; an introduction passage 36 for leading the neutralized drain to the drain tank; and a drain lead-out passage 42 for leading the drain in the drain tank to an additional heating circulation passage 11; and drain discharge control means for discharging the drain in the drain tank to the outside of the additional heating circulation passage. When the detection water level of the second water level sensor does not reach the second predetermined value and the detection water level of the first water level sensor has reached the first predetermined value, the drain discharge control means discharges the drain to the outside of the additional heating circulation passage. On the basis of whether or not the detection water level of the first water level sensor has dropped to be lower than the first predetermined value, it is determined whether it is occurrence of clogging abnormality of the introduction passage or occurrence of abnormality in the second water level sensor. |
