Geothermal heat pump technology uses electricity to pump heat from the ground loop into a building to heat it during the winter, and pump heat from a building to the ground loop to cool the ...
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.
[95] [96] Most of the energy used in homes was for space heating (34%) and water heating (19%), much more than the amount used for space cooling (16%) and refrigeration (7%). [97] Businesses use similar percentages for space cooling and refrigeration. They use less for space and water heating but more for lighting and cooking. [98]
In geothermal heating projects the underground is penetrated by trenches or drillholes. As with all underground work, projects may cause problems if the geology of the area is poorly understood. In the spring of 2007 an exploratory geothermal drilling operation was conducted to provide geothermal heat to the town hall of Staufen im Breisgau.
A cold weather rule (CWR) or cold weather law is a regulation that prohibits public utility companies from disconnecting customers who are unable to pay for the energy used to heat their homes during the winter. Such regulations may also require utility companies to reconnect customers during those periods. Cold weather rules help prevent ...
Cold district heating is a technical variant of a district heating network that operates at low transmission temperatures well below those of conventional district heating systems and can provide both space heating and cooling. Transmission temperatures in the range of approx. 10 to 25 °C (50–77 °F) are common, allowing different consumers ...

Not all regions and sites are suitable for earth-air heat exchangers. Conditions which may hinder or preclude proper implementation include shallow bedrock, high water table, and insufficient space, among others. In some areas, only cooling or heating may be afforded by earth-air heat exchangers.
