PROBLEM TO BE SOLVED: To enable an accuracy in detection of clogged fin to be assured without widening an arrangement range of a temperature sensitive part 10a of a unit can type complex heat source comprising a pair of burners arranged side-by-side within a unit can body 1, a pair of heat exchangers arranged side-by-side at the upper part of the can body and a partition wall 8 for parting inside the can body into two combustion chambers in which a temperature sensor 10 having the temperature sensitive part 10a at its extremity end is inserted into a hollow part 8c of the partition wall 8 so as to detect occurrence of clogged fin in one heat exchanger on the basis of a detected temperature of the temperature sensor.SOLUTION: The partition wall 8 is provided with a closing part 8d for closing a clearance between both heat exchangers. In addition, the closing part 8d is not provided within a prescribed forward or rearward range of the partition wall 8 including a portion where the temperature sensitive part 10a of the temperature sensor 10 is positioned, but both combustion chambers are communicated with a clearance between both heat exchangers. |
