An earth type heat pump having a heat exchanger including an evaporator coil and a compressor, condenser, receiver and expansion valve in series with the evaporator coil for delivering heat picked up at the heat exchanger from the condenser, and heat pickup tubes positioned vertically in the earth and connected with the heat exchange structure for passively supplying heat from the earth to the heat exchanger by means of a refrigerant passing between the heat pickup tubes and heat exchange structure, and the corresponding method of supplying heat from an earth type heat pump. In one modification the heat of the earth is supplemented by a solar heating system including a collector and heater tubes connected to the collector positioned vertically and interspersed with the heat pickup tubes of the heat pump. In another modification of the invention, heat transfer between the vertically positioned tubes is promoted by structure for and the method of moistening the earth around the vertical heat pickup tubes and the heater tubes.

The method of providing heat from an earth type heat pump comprising connecting a heat exchanger, compressor, condenser, receiver and expansion in series, whereby refrigerant in the form of gas received at the compressor is compressed and passed to the condenser wherein heat is given off and the gas is liquefied and passed to the receiver from which it is passed through the expansion valve into the heat exchanger, providing heat to the heat exchanger through heat pickup tubes vertically positioned in the earth to evaporate the refrigerant in the heat exchanger into a refrigerant gas, assisting the heat pickup of the heat pickup tubes by supplying solar heat to the earth through a collector, heater tubes vertically positioned in the earth adjacent the heat pickup tubes and means for circulating a heat transfer medium through the solar collector and heater tubes, and moistening the earth around the heat pickup tubes to increase the heat transfer from the earth to the heat pickup tubes.
