A complete aerothermal installation is a significant project. It begins with calculating the thermal loads of the home, sizing the equipment based on actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the DHW tank and 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 air condition the home, and simultaneously heats a domestic hot water tank of approximately 200 litres for showers and taps. It's an all-in-one solution, ideal for detached houses and large properties. Its payback period compared to a traditional gas + air conditioning system is 8 to 12 years in the local climate.

Annual gas boiler maintenance typically costs between €90 and €130, including the certificate. Repair of a simple fault (sensor, valve, pressure switch) costs €80-€180 plus parts. A full replacement of a natural gas boiler with a condensing model costs around €1,400, including installation, depending on the brand and power. We diagnose circuits with a thermal imaging camera, detect leaks without breaking the floor when 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 be seized, the expansion vessel may have lost pressure, or the thermostat may have become deconfigured. We see this every November.

5-7 years manufacturer warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day guarantee on labour and recommended annual inspections. A condensing boiler installed costs around €400, depending on the brand, power, and necessary work. The replacement cost is usually recovered in 4-6 years due to gas savings. Electric underfloor heating for a 90 m² home costs around €4,000 with thermostats per zone. Individual new radiators cost between €80-€180 each, depending on size and model. A programmable thermostat with installation costs €120-€280, depending on the brand.

The cost of annual maintenance in La Bordeta typically ranges from €160 to €4,165. The final amount depends on the property's condition, materials, and labour time.
