PROBLEM TO BE SOLVED: To stabilize hot water feeding temperature, simplify hot water feeding function of a heat source device and provide convenience at the heat source device.SOLUTION: This invention relates to a heat source device [2] for heating an after-burning heat exchanger [6] for heating bath tub water and a heat exchanger [8] for heating heat medium or fed water through a common heat source [a burner 4]. There are provided a hot water feeding pipe [10] for flowing hot water heated by the heat exchanger; a hot water feeding pipe [12] connected to a pipe [14-1] for returning bath tub water to a bath tub in the after-burning pipe [14] to flow the hot water from the hot water feeding pipe; reverse flow prohibiting means [18] installed between a pipe path connection part [P1] and the after-burning heat exchanger [a reverse flow prohibiting area 16] to prohibit reverse flow of hot water. Flowing-in of hot water to the after-burning heat exchanger side is prohibited by the reverse flow prohibiting means when hot water is flowed to the after-burning pipe through the hot water feeding pipe path.SELECTED DRAWING: Figure 1 【課題】注湯温度の安定化とともに、熱源装置の注湯機能の簡易化および熱源装置の利便性を図る。【解決手段】浴槽水を加熱する追焚熱交換器（６）と、熱媒または給水を加熱する熱交換器（８）とを共通の熱源（バーナ４）で加熱する熱源装置（２）であって、熱交換器で加熱された湯水を流す給湯管路（１０）と、追焚管路（１４）のうち浴槽水を浴槽側に戻す管路（１４−１）側に接続され給湯管路から湯水を流し込む注湯管路（１２）と、管路の接続部（Ｐ１）と追焚熱交換器との間（逆流阻止エリア１６）に設置されて、湯水の逆流を阻止する逆流阻止手段（１８）と、を備え、注湯管路より追焚管路に湯水を流し込む際、追焚熱交換器側に湯水の流入を逆流阻止手段によって阻止する。【選択図】 図１
