Geothermal heat pumps and geothermal exchange may be used to tap the geothermal energy stored in the Earth's mantle.

Geothermal Heat Pumps

Systems that use the stable underground temperature to provide heating, cooling, and hot water for buildings.

Geothermal Exchange

The process of using the Earth's constant underground temperature to heat and cool buildings.

Earth's Mantle

The thick layer of rock between the Earth's crust and core, making up about 84% of Earth's volume and involved in plate tectonic movements.
