A complete aerothermal system installation is a serious project. It begins with calculating the home's thermal loads, sizing the equipment according to actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the domestic hot water tank and the outdoor unit, and finally, a fixed price quote. The air-to-water heat pump, also known as aerothermal, goes a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to condition the home, and at the same time heats a domestic hot water tank of approximately 200 litres for use in showers and taps. It's an all-in-one solution, ideal for large houses and chalets. Its payback period compared to a traditional gas boiler and air conditioning system is 8 to 12 years in this climate zone.
