PROBLEM TO BE SOLVED: To bury a heat exchanger to serve both for the reinforcement of easily collapsible earth part around the bank of a storage reservoir. SOLUTION: The constructing method of a heat source system comprises the digging process of downward holes 14 in easily collapsible earth parts 12 around the bank of a storage reservoir 10, the inserting process of a grout liquid send-out pipe 41 together with a geothermy heat exchanger 21 equipped with an antifreeze circulating passage, a process wherein grout liquid is pumped by a grout liquid pump 42 on the ground to fill a gap between the geothermy heat exchanger 21 as well as the grout liquid send-out pipe 41 and the downward hole 14 while impregnating the grout into the surrounding earth parts 12 and the curing process of the grout liquid in accordance with the elapse of time. The geothermy heat exchanger 21 is buried into the earth parts 12 around the bank of the storage reservoir 10 whereby the collapse of the earth T can be prevented. The grout liquid is impregnated into the surrounding earth T of the geothermy heat exchanger 21 whereby a heat transfer rate is improved compared with the earth individually and the performance of the geothermy heat exchanger 21 is improved.
