PROBLEM TO BE SOLVED: To provide a heat source machine capable of preventing degradation in efficiency even if the return temperature of a heat medium circulated in a heating circuit or the like is high.SOLUTION: In a circulation path for circulating a heat medium so as to return to a latent heat recovery heat exchanger 9 after via the latent heat recovery heat exchanger 9 and a sensible heat recovery heat exchanger 8 in this order and further via an external heat radiation unit 2, a heat storage unit 23 absorbing heat from the heat medium and storing the heat is inserted into a return part from the heat radiation unit 2. By decreasing a temperature of the heat medium reaching the latent heat recovery heat exchanger 9 by the absorption of heat by the heat storage unit 23, efficiency of the latent heat recovery heat exchanger 9 is improved and the heat stored in the heat storage unit 23 is used for preheating supply water for supplying hot water or the like. |
