    • PROBLEM TO BE SOLVED: To provide technology capable of preventing corrosion of a constituent material of an evaporator caused by a corrosive gas included in an exhaust gas with an inexpensive and simple constitution while keeping high efficiency, in a heat source system comprising a compression-type heat pump circuit for allowing a refrigerant to successively circulate through a compressor for compressing the refrigerant, a condenser for radiating heat from the refrigerant, an expansion valve for expanding the refrigerant, and the evaporator for allowing the refrigerant to absorb heat, and an exhaust gas passage for supplying the exhaust gas discharged from a combustion device burning a fuel such as an engine as a heat source of the evaporator. SOLUTION: This heat source system comprises a latent heat recovering heat exchanger 31 for preheating supplied water by latent heat of steam included in the exhaust gas E circulated between the combustion device 2 and the evaporator 13 in the exhaust gas passage 3, and a condensate water recovering portion 32 for recovering the condensate water CW generated in the exhaust gas passage 3.
