Zusammenfassung:	To provide an instantaneous hot water tapping device capable of controlling the temperature of hot water in a hot water storage tank by taking unevenness of a bypass ratio which could be achieved by a bypass ratio adjustment device properly into consideration.SOLUTION: A controller 45 of an instantaneous hot water tapping device 20 includes: a bypass ratio measurement unit 48 for measuring an actual bypass ratio in a state where a flow rate adjusting valve 33 as a bypass ratio adjusting device is controlled to be a predetermined opening; and a hot water temperature control unit 47 for controlling the temperature of hot water in a hot water storage tank 21 (hot water storage temperature). The hot water storage temperature control unit 47 changes an upper limit value or a target value of the hot water storage temperature according to a measurement value of the bypass ratio.SELECTED DRAWING: Figure 1 【課題】バイパス比調整装置により実現し得るバイパス比のばらつきを適切に考慮した態様で貯湯タンク内の湯水の温度を制御することができる即時出湯装置を提供する。【解決手段】即時出湯装置２０のコントローラ４５は、バイパス比調整装置としての流量調整弁３３が所定の開度に制御されている状態での実際のバイパス比を測定するバイパス比測定部４８と、貯湯タンク２１内の湯水の温度（貯湯温度）を制御する貯湯温度制御部４７とを有する。貯湯温度制御部４７は、バイパス比の測定値に応じて貯湯温度の上限値又は目標値を変化させる。【選択図】図１
