    Over the long term, however, bills are expected to be much lower. Switching from gas hookups to networked geothermal heating could cut energy costs by 15 to 20%, Eversource estimates.

  3. 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.

  4. Geothermal heating - Wikipedia

    en.wikipedia.org/wiki/Geothermal_heating

    Geothermal systems tend to benefit from economies of scale, so space heating power is often distributed to multiple buildings, sometimes whole communities. This technique, long practiced throughout the world in locations such as Reykjavík , Iceland ; [ 7 ] Boise , Idaho ; [ 8 ] and Klamath Falls , Oregon ; [ 9 ] is known as district heating .

    Paleo-Indians first used geothermal hot springs for warmth, cleansing, and minerals. [3] Pacific Gas and Electric opened the US' first commercial geothermal power plant at The Geysers in California in September 1960, initially producing eleven megawatts of net power. The Geysers system grew into the world's largest, with an output of 750 MW. [3]

    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 ...

    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.
