To restrain a decrease in convenience of bathtub washing when a drainage rate is decreased by clogging of a drainage port.SOLUTION: A water heater according to the present disclosure comprises detection means for detecting a drainage rate of bathtub water in a bathtub, a first detergent flow passage for supplying a first detergent to the bathtub, a second detergent flow passage for supplying a second detergent, a rinse water flow passage for supplying water as rinse water to the bathtub, a discharge part arranged in the bathtub, and capable of discharging the first detergent, the second detergent, and the rinse water into the bathtub, and a control part for performing bathtub washing by controlling operation for supplying the first detergent, the second detergent, and the rinse water to the bathtub when draining the bathtub water. The control part performs the bathtub washing in a first mode for supplying the rinse water after putting the first detergent into the bathtub, when the drainage rate is higher than a determination value, and performs the bathtub washing in a second mode for putting the second detergent after putting the first detergent into the bathtub, and supplying the rinse water thereafter, when the drainage rate is equal to or lower than the determination value.SELECTED DRAWING: Figure 2 【課題】排水口の詰まりにより排水速度が低下している場合の浴槽洗浄の利便性の低下を抑制する。【解決手段】本開示の給湯機は、浴槽の浴槽水の排水速度を検出する検出手段と、浴槽に、第一洗剤を供給する第一洗剤流路と、第二洗剤を供給する第二洗剤流路と、浴槽に、すすぎ水として水を供給するすすぎ水流路と、浴槽に配置され、第一洗剤、第二洗剤、及び、すすぎ水を浴槽内に吐き出し可能な吐出部と、浴槽水の排水時に、浴槽への第一洗剤、第二洗剤、及び、すすぎ水の浴槽への供給動作を制御して浴槽洗浄を行う制御部とを備える。制御部は、排水速度が判定値より速い場合、浴槽に、第一洗剤を投入したあと、すすぎ水を供給する第一モードで浴槽洗浄を実行し、排水速度が判定値以下の場合、浴槽に、第一洗剤を投入したあと、第二洗剤を投入し、その後、すすぎ水を供給する第二モードで浴槽洗浄を実行する。【選択図】 図２
