Geothermal heat pumps (thermodynamic heating systems with buried loops) capture ground-source heat energy and transfer is to the home.
This technique is on the rise, offering economic ans ecological advantages for individual housing as well as small apartment buildings, in both new construction and refurbishing projects.

To harness the energy supply contained in the earth's soil, the geothermal process utilises a refrigerating circuit based on a thermodynamic principle: ground heat, continually replenished by the rain, wind, and sun's rays, is collected by heat-absorbing loops buried 60 cm below the surface of the ground or by geothermal probes, sunk vertically into the soil. The loops lie beneath the garden's surface and are thus invisible and extremely durable. The great quantity of energy absorbed by the soil and the adequate design of the loops guarantee efficient heat collection for the life of the system.

A thermodynamic generator adds extra value to this renewable "free" energy source by transferring it to the house interior, meeting 100% of the home's heating requirements.
