PROBLEM TO BE SOLVED: To shorten time required for defrosting of an evaporator.SOLUTION: A heating system includes: a heat exchanger 44 for defrosting that performs heat exchange between exhaust outflowing from a ventilation heat exchanger 34 and a heat medium outflowing from a heat exchanger 35 for heating, and heats exhaust outflowing from the ventilation heat exchanger 34; and a ventilation flue formation member 36 that forms a ventilation flue guiding exhaust heated by the heat exchanger 44 for defrosting to an evaporator 14. Exhaust outflowing from the ventilation heat exchanger 34 is heated by the heat exchanger 44 for defrosting to perform defrosting of the evaporator 14.SELECTED DRAWING: Figure 1 |
