PROBLEM TO BE SOLVED: To provide a one can type complex heat source machine not only detecting clogging of a fin of a heat exchanger on one side but also making the detection of high accuracy while suppressing increase of costs. SOLUTION: A space between a first burner 2-1 and a first heat exchanger 3-1 is applied as a first combustion chamber 7-1, a space between a second burner 2-2 and a second heat exchanger 3-2 is applied as a second combustion chamber 7-2, and a partitioning wall 8 is disposed to define the first combustion chamber 7-1 and the second combustion chamber 7-2. A communicating section 83 penetrating through both wall plates 81, 81 of the partitioning wall 8 to make the first combustion chamber 7-1 communicate with the second combustion chamber 7-2, is disposed in front of a longitudinal central section of the partitioning wall 8. A temperature sensing section 10a of a temperature sensor 10 is disposed on the communicating section 83. When the fin of the heat exchanger on one side is clogged, a combustion gas in the combustion chamber on one side corresponding to the heat exchanger flows in a state of deflecting to a partitioning wall 8 side, and proceeds to the other combustion chamber through the communicating section 83. Temperature rise of the communicating section 83 is detected by the temperature sensor 10 to discriminate presence or absence of the clogging of fin. COPYRIGHT: (C)2011,JPO&INPIT
