PURPOSE: A soil heating apparatus using the surplus heat of a house and a heat pump is provided to store and use the surplus heat of daytime solar heat in the ground, thereby reducing energy costs consumed for heating the house. CONSTITUTION: A soil heating apparatus using the surplus heat of a house and a heat pump includes a heat pump(10), a heat storage tank(20), a house heat exchanger(40), and a soil heating heat exchanger(45). The heat storage tank is connected to the heat pump with a first circulation line(21) so that the heat storage tank stores and circulates a thermal medium with a first pump(22). The house heat exchanger is connected to the heat storage tank with a second circulation line(41) so that the house heat exchanger circulates the heat medium inside the heat storage tank with a second pump(42). The second circulation line has a branch line(44), and the branch line buried in the ground is the soil heating heat exchanger. |
