The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to climate control the home, and at the same time heats a domestic hot water tank of approximately 200 litres for showers and taps. It handles everything in a single unit, ideal for chalets and large homes. Its payback compared to a traditional gas + air system is 8 to 12 years in the local climate. A complete aerothermal installation is a serious project. It begins with calculating the thermal loads of the home, sizing the unit according to actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the DHW tank and outdoor unit, and a fixed quote.
