The eco- conscious choice to elevate your energy performance Heat sources found in the air, the earth and in groundwater provide a clean, free and abundant form of energy. Not only does this substantially shrink CO2 emissions, but it also takes energy efficiency to another level. So, how do you run it?

By mobilising heat-conducting fluid in underground pipes, this method redirects heat from the ground to a home heating system. We deploy this technology in our Geolia range. Spotlight on aerothermal systems These systems seek to collect heat sourced from the air, including spells of cold weather, before heating up the home. Using a closed circuit refrigerant, this energy is then converted from liquid to gas. We deploy this technology in our Alfea, Ixtra M and Loria ranges. How do heat pumps work? ACHIEVED UP TO 2 ENERGY PERFORMANCE CLASSES IN ITS HEAT PUMP INSTALLATION PROCESS* *Estimated housing label improvements through calculations using the example of a category G single-family home in the H2B climate zone (3CL calculation of conventional consumption in households to determine energy performance). Did you know? Compared to standard boilers, Air/Water heat pumps emit 3 to 4 times less CO2. 13 Heat pumps
