Zusammenfassung: | To provide a hot water supplying heating system capable of preventing residual old water in a pipe at the time of shipping from being discharged in a bathtub at the time of construction, and capable of feeding water to each place of each instrument or into a pipe at the time of construction.SOLUTION: In a hot water supply heating system 2, a controller 70 is configured to execute: first water replacement operation of replacing water left in a pipe conduit of a heating system and in a pipe conduit of a bathtub system with new water supplied from the outside, to discharge water left in pipe and at the same time supply new water to a heater 40; second water replacement operation of replacing water left in the pipe with new water in a state where burners 203, 204 do not perform combustion, to discharge water left in the pipe and at the same time supply new water to a tank part 10; and third water replacement operation of replacing water left in the pipe with new water, to discharge water left in the pipe and at the same time supply new water to a heat pump part 30.SELECTED DRAWING: Figure 19
【課題】出荷段階で配管内に残り古くなった水が、施工時に浴槽内に排出されるのを防ぎ、施工時に各器具内の各所や配管内に水を送り込む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では、制御装置70は、暖房系統の管路内および浴槽系統の管路内に残っている水を外部から供給された新たな水に換水して配管内に残っている水を排水するとともに新たな水を暖房装置40に供給する第1換水動作と、バーナ203、204の燃焼をしない状態で配管内に残っている水を新たな水に換水して配管内に残っている水を排水するとともに新たな水をタンク部10に供給する第2換水動作と、配管内に残っている水を新たな水に換水して配管内に残っている水を排水するとともに新たな水をヒートポンプ部30に供給する第3換水動作と、の制御を実行する。【選択図】図19 |
