Equipped with an independent thermodynamic module which recovers the energy taken in the ground, this Sofath heat pump ensures the totality of the production of hot water during all the year. Geothermic collecting is done with the horizontal one. The calories present in the ground are recovered via a refrigerant and heat is then redistributed with the hot-water heater. 30 m2 approximately of horizontal sensor are enough for a balloon to 300 liters. The yearly consumption is then about 1.900 à2 200 kWh.
