| Zusammenfassung: | To provide a hot water supply heating system capable of suppressing deterioration of efficiency of a heat pump part and suppressing influence on water level detection of a water level sensor, in a case of mutually switching reheating operation and hot-water accumulation operation.SOLUTION: In a hot water supply heating system 2, a controller 70 is configured to, in the middle of transferring from reheating operation of heating water in a bathtub 50 using a combustor 201 and a heat pump part 30 to hot-water accumulation operation of heating water supplied from a water supply source using the combustor 201 and the heat pump part 30 and then supplying the water to the bathtub 50, execute control of stopping combustion operation of the combustor 201, stopping driving of a bath pump 235 and opening a defrosting valve 308 in a state of continuing heating operation of the heat pump part 30.SELECTED DRAWING: Figure 8
【課題】追い焚き動作と湯張り動作とを互いに切り替える場合に、ヒートポンプ部の効率が低下することを抑えることができるとともに、水位センサの水位検出に及ぼす影響を抑えることができる給湯暖房システムを提供すること。【解決手段】給湯暖房システム２において、制御装置７０は、燃焼装置２０１およびヒートポンプ部３０を用いて浴槽５０の内部の水を加熱する追い焚き動作から、燃焼装置２０１およびヒートポンプ部３０を用いて水供給源から供給された水を加熱し浴槽５０に供給する湯張り動作へ移行する途中では、ヒートポンプ部３０の暖房運転を継続した状態で、燃焼装置２０１の燃焼動作を停止し、風呂ポンプ２３５の駆動を停止し、除霜弁３０８を開く制御を実行する。【選択図】図８ |
