PROBLEM TO BE SOLVED: To provide a bath water heater capable of highly accurately regulating the temperature of hot water in a bathtub without charging water into the bathtub and ensuring a bather to comfortably take a bath.SOLUTION: A bath water heater 1 of the present invention comprises: air bubble supply means (a bathtub-side circulation flow path 6, an air bubble generator 10, and a bathtub-side circulation pump 12) for supplying air bubbles to a bathtub 2; hot-water-temperature detection means (outgoing-pipe-internal-temperature detection means 11 and return-pipe-internal-temperature detection means 13) for detecting a hot water temperature of the bathtub 2; and control means (a control unit 30) for controlling the bubble supply means to operate so that the hot water temperature of the bathtub 2 falls down to a target temperature. 【課題】浴槽に注水することなく浴槽の湯温を高精度に調整でき、入浴者が安全で快適に入浴することを可能とする風呂給湯装置を提供すること。【解決手段】本発明の風呂給湯装置１は、浴槽２に気泡を供給する気泡供給手段（浴槽側循環流路６、気泡生成装置１０、浴槽側循環ポンプ１２）と、浴槽２の湯温を検知する湯温検知手段（往き管内温度検知手段１１、戻り管内温度検知手段１３）と、浴槽２の湯温が目標温度まで低下するように、気泡供給手段の動作を制御する制御手段（制御部３０）と、を備える。【選択図】図１
