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. Direct exchange geothermal heat pump - Wikipedia

   en.wikipedia.org/wiki/Direct_exchange_geothermal...

   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.

4. Geothermal heating - Wikipedia

   en.wikipedia.org/wiki/Geothermal_heating

   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]

   “Even though the installation price of a geothermal system can be several times that of an air-source system of the same heating and cooling capacity, the additional costs may be returned in ...

6. Radiant heating and cooling - Wikipedia

   en.wikipedia.org/wiki/Radiant_heating_and_cooling

   Radiant systems using low temperature heating and high temperature cooling are typical example of low-exergy systems. Energy sources such as geothermal (direct cooling / geothermal heat pump heating) and solar hot water are compatible with radiant systems. These sources can lead to important savings in terms of primary energy use for buildings.

7. Renewable thermal energy - Wikipedia

   en.wikipedia.org/wiki/Renewable_thermal_energy

   Another example of Renewable Thermal is a Geothermal or ground source Heat Pump (GHP) system, where thermal stored in the ground from the summer is extracted from the ground to heat a building in another season. This example system is "renewable" because the source of excess heat energy is a reliably recurring process that occurs each summer ...
