A heat pump in combination with heat and cold storage. A ground source heat pump (also geothermal heat pump) is a heating/cooling system for buildings that use a type of heat pump to transfer heat to or from the ground, taking advantage of the relative constancy of temperatures of the earth through the seasons.
First successful geothermal test boring in Indonesia at Kawah Kamojang in 1926. Geothermal power in Indonesia is an increasingly significant source of renewable energy.As a result of its volcanic geology, it is often reported that Indonesia has 40% of the world's potential geothermal resources, estimated at 28,000 megawatts (MW).

That heat can be extracted with a geothermal heat pump more efficiently than it can be generated by conventional furnaces. [10] Geothermal heat pumps are economically viable essentially anywhere in the world. In theory, geothermal energy (usually cooling) can also be extracted from existing infrastructure, such as municipal water pipes. [14]
Geothermal units are being built at Louisville's Norton Commons. A series of loops are used -- digging down around 350 feet -- for an alternative to traditional HVAC systems.
A geothermal well was used to heat greenhouses in Boise in 1926, and geysers were used to heat greenhouses in Iceland and Tuscany at about the same time. [9] Charles Lieb developed the first downhole heat exchanger in 1930 to heat his house. Geyser steam and water began heating homes in Iceland in 1943. Global geothermal electric capacity.
A direct exchange (DX) geothermal heat pump is a type of ground source heat pump in which refrigerant circulates through copper tubing placed in the ground unlike other ground source heat pumps where refrigerant is restricted to the heat pump itself with a secondary loop in the ground filled with a mixture of water and anti-freeze.
