A complete aerothermal installation is a serious project. It starts with calculating the thermal loads of the home, sizing the equipment according to real needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the domestic hot water tank and outdoor unit, and a fixed quote. An air-to-water heat pump, also called aerothermy, goes a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to regulate the indoor climate, 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 detached houses and large homes. Its payback period compared to a traditional gas + air system is 8 to 12 years in the local climate.

We diagnose circuits with thermal cameras, detect leaks without breaking the floor where possible, and repair the manifold or valves as needed. We identify the real cause (humidity, settlement, worn fittings) before acting. Annual gas boiler maintenance, between 90 and 130 euros with certificate included. Repair of a simple fault (sensor, valve, pressure switch), 80-180 euros plus parts. Complete replacement of a natural gas boiler with a condensing model, 1,400 euros installation included depending on brand and power.

Official manufacturer's warranty (5-7 years) plus our labour coverage. 5-7 years official manufacturer's warranty depending on brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day labour coverage and recommended annual inspections. Electric underfloor heating for a 90 m² home costs around 4,000 euros with zone thermostats. We replace individual new radiators for 80-180 euros each depending on size and model. Programmable thermostat with installation, 120-280 euros depending on brand.

The price for insulation in L'Hospitalet de Llobregat usually ranges between 208 and 2970 euros. The final figure depends on the condition of the property, the materials, and the working time.
