Geothermal heat pumps
- warm water, heating and cooling
Main features
- is suitable for warm water generation and can be used for heating in buildings which contain heating system based on water circulation. It can also be used as a part of cooling system.
- works 24/7
- the heat pump produces 3 units heat energy for every 1 unit of electricity it consumes
- system needs electricity
Additional features
- geothermal heat pump utilises energy absorbed at the earth’s surface from solar energy. In deep wells heat pumps also utilises heat from earth’s core
- if loop is installed to water, it is important that the temperature of the loop never goes below zero. If it does, ice is formed around the pipes and buoyancy will lift the pipes to the surface
- life cycle of a ground heat pump is around 15-30 years and compressor 10-15 years
