A complete aerothermal installation is a significant project. It begins with calculating the home's thermal loads, sizing the unit 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 providing a fixed quote. The air-to-water heat pump, also known as aerothermal energy, 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 simultaneously heats a domestic hot water tank of approximately 200 litres for showers and taps. It handles everything in a single unit, ideal for large houses and chalets. Its payback period compared to a traditional gas + air system is 8 to 12 years in the local climate.

Annual gas boiler maintenance costs between €90 and €130, including the certificate. Repair of a minor fault (sensor, valve, pressure switch) costs €80-€180 plus parts. A complete replacement of a natural gas boiler with a condensing model costs €1,400 including installation, depending on the brand and power rating. We diagnose circuits using thermal imaging cameras, detect leaks without floor damage where possible, and repair the manifold or valves as needed. The typical problem arises when you try to turn on the boiler or underfloor heating after eight months of disuse and it doesn't respond. The pump may have seized, the expansion vessel may have lost pressure, or the thermostat may have been reset. We see this every November.

Manufacturer warranty of 5-7 years depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day labour coverage and recommended annual inspections. A complete heat pump boiler installation costs around €400, depending on the brand, power rating, and necessary work. The replacement cost is typically recovered through gas savings within 4-6 years. Electric underfloor heating for a 90 m² home costs around €4,000 with zoned thermostats. We replace individual new radiators for €80-€180 each, depending on size and model. A programmable thermostat with installation costs €120-€280, depending on the brand.
