Zusammenfassung:	To provide a hot-water supply device which allows an operator to more safely carry out maintenance work.SOLUTION: A hot-water supply device having a hot-water storage tank and a heat pump comprises: a relay 31 which opens/closes a power supply line 11 of an AC voltage; a rectification part 34; a smoothing electrolytic capacitor 35; a compressor driving inverter 36 connected to the electrolytic capacitor 35; a fan motor driving inverter 37 connected to the electrolytic capacitor 35; a voltage detection part 38 which detects a voltage of the electrolytic capacitor 35; and a heat pump control part 23. When stopping the operation of the heat pump, the heat pump control part 23 stops the compressor driving inverter 36 while allowing the fan motor driving inverter 37 to continue its operation, and at the same time the heat pump control part controls the main relay 31 to be in an open-circuit state. In this condition, if the detected voltage of the electrolytic capacitor 35 decreases to a reference voltage or lower, the heat pump control part stops the fan motor driving inverter 37.SELECTED DRAWING: Figure 2 【課題】作業者がより安全にメンテナンス作業を行うことができる給湯装置を提供する。【解決手段】貯湯タンクとヒートポンプとを有する給湯装置であって、交流電圧の電源ライン１１を開閉するリレー３１と、整流部３４と、平滑用の電解コンデンサ３５と、電解コンデンサ３５に接続されたコンプレッサ駆動用インバータ３６と、電解コンデンサ３５に接続されたファンモータ駆動用インバータ３７と、電解コンデンサ３５の電圧を検出する電圧検出部３８と、ヒートポンプ制御部２３と、を備え、ヒートポンプ制御部２３は、ヒートポンプの運転を停止する場合、ファンモータ駆動用インバータ３７の作動を継続させた状態でコンプレッサ駆動用インバータ３６を停止させるとともにメインリレー３１を開路状態に制御し、この状態で電解コンデンサ３５の検出電圧が基準電圧以下に低下すると、ファンモータ駆動用インバータ３７を停止させるように構成されている。【選択図】図２
