  2. Ground source heat pump - Wikipedia

    en.wikipedia.org/wiki/Ground_source_heat_pump

    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.

  3. Geothermal heating - Wikipedia

    en.wikipedia.org/wiki/Geothermal_heating

    Heat pipes extend the temperature range down to 5 °C (41 °F) as they extract and "amplify" the heat. Geothermal heat exceeding 150 °C (302 °F) is typically used for geothermal power generation. [6] In 2004 more than half of direct geothermal heat was used for space heating, and a third was used for spas. [1]

  4. Direct exchange geothermal heat pump - Wikipedia

    DX system being drilled in the 1980s. 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.

    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.

  6. Geothermal energy - Wikipedia

    en.wikipedia.org/wiki/Geothermal_energy

    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.

  7. Closed-loop geothermal - Wikipedia

    en.wikipedia.org/wiki/Closed-loop_geothermal

    Closed-loop geothermal systems (also known as “advanced geothermal systems” or “AGS”) are a type of engineered geothermal energy system containing subsurface working fluid that is heated in a hot rock reservoir without direct contact with rock pores and fractures.: [1] [2] [3] Instead, the subsurface working fluid stays inside a closed loop of deeply buried pipes that conduct Earth’s ...

    The Sonoma Calpine 3 geothermal power station of The Geysers. Geothermal energy in the United States was first used for electric power production in 1960. The Geysers in Sonoma and Lake counties, California was developed into what is now the largest geothermal steam electrical plant in the world, at 1,517 megawatts. Other geothermal steam ...

  9. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    An air source heat pump can be used to air condition the building during hot weather, and to warm the building using heat extracted from outdoor air in cold weather. Air-source heat pumps are generally uneconomic for outdoor temperatures much below freezing. In colder climates, geothermal heat pumps can be used to extract heat from the ground ...
