Solar energy is stored in the ground, air and water. With the help of the heat pump this natural heat is absorbed and transferred to a CFC free refrigerant. The latter evaporises, is mechanically compressed and again fluidized through the heat release of the heating system. This principle is identical to the mechanics of a fridge and functions in both heating and cooling modes.
Tax breaks/tax relief for heat pump programs will renumerate your decision for this environmentally friendly heating system.
