Heat pumps

A heat pump is a device that heats rooms and/or domestic hot water. A heat pump extracts low-temperature heat from the ground (up to 500 meters deep) or outside air. By supplying auxiliary energy (usually electricity), the temperature is raised and the heat is transferred to air or water.

Renewable energy provided by heat pumps is defined in the EU Renewable Energy Directive (RED II) as the amount of useable energy derived from heat pumps minus the amount of energy used to run the heat pumps.
