Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heat source machine which warns a user of necessity of maintenance.SOLUTION: A heat source machine including a burner and a heat exchanger to supply hot water heated via the heat exchanger, is provided with a control means for acquiring and integrating operation information related to an operation amount or operation time. On condition that an integration value of operation information integrated by the control means reaches a predetermined reference value, a warning operation is performed which warns that a maintenance period has come. The warning operation is switched when a predetermined time is elapsed after a predetermined operation start condition is satisfied, between a normal mode and a warning mode that supplies hot water on the basis of a reference different from the normal mode.
