A geothermal heat utilization system according to the present disclosure comprises: a pumping well; a water injection well; piping extending from the pumping well to the water injection well; a pump capable of feeding ground water from the pumping well to the water injection well via the piping; a heat exchanger provided to the piping; a control valve that is provided to the piping and is capable of adjusting the flow rate of groundwater within the piping; and a control device that, if the operation frequency during inverter control of the pump has reached the minimum frequency, adjusts the flow rate of ground water to be injected into the water injection well by controlling the control valve so as to constrict the flow rate within the piping.
