ABSTRACT:
An underground water warmed by the geothermy in an aquifer is pumped up by a pumping means disposed in a pump-up well and the pumped up underground water is introduced into a heat exchanger located in the pump-up well near the opening thereof. The heat exchanger is connected to a heat radiating pipe laid under a road or a building structure on the ground through feed and return conduits. An antifreezing fluid is filled in the heat radiating pipe and circulates through the heat radiating pipe and the heat exchanger through the conduits. The antifreezing fluid warmed in the heat exchanger by the heat exchanging operation stores the heat in the road and transfers the heat to the snow on the ground during the passing through the heat radiating pipe by the heat radiating operation, whereby snow lying on the road is melted without sprinkling water. The underground water cooled after the heat exchanging operation is discharged from the heat exchanger to be introduced into a water returning artesian well to store the water or to be discharged into a public discharge channel.
