• Ground heat is absorbed using buried loops, a system of polyethylene-coated copper coils containing refrigerant fluid.

• The loops are buried 60 cm below the ground, over a surface area that is 100% to 120% the size of the home to be heated.

• A hydraulic distribution circuit transfers the useful heat into the house via a underfloor heating, radiators (maximum temperature of 47°C) or any other solution that uses hot water to transmit heat.
