7. 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]

   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.
