Terra Geothermal heat pumps for heating, air conditioning and hot water
Flat collectors are cheap to install but require a large surface below the garden.
Heat pumps with deep drilling are the safest variant: they require a minimum of space, have a long service life and are suitable for heating and air conditioning.
The most efficient geothermal heat application for confined areas.
Groundwater technology is highly efficient and requires little space: the energy is drawn from the earth using two wells.
