PURPOSE: A geothermal heat pump for a house is provided to supply hot water rapidly even though the geothermal heat pump is re-operated after being stopped because a rapid hot water pipe is installed in a storage tank storing energy. CONSTITUTION: A geothermal heat pump for a house comprises a heat pump unit(10), a cooling and heating unit(20), and a geothermal storage unit. The heat pump unit exchanges heat with at least one of underground heat exchangers. The cooling and heating unit is connected to exchange heat with the heat pump unit. The geothermal storage unit is connected between the heat pump unit and the cooling and heating unit and stratifies the energy, generated in the heat pump unit, in order to store. The geothermal storage unit comprises a storage tank and a rapid hot water pipe. Circulating water, circulating between the heat pump unit and the cooling and heating unit, passes through the storage tank to store the energy in the storage tank. The rapid hot water pipe exchanges heat with the circulating water in the storage tank.
