The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coil units to condition the home, and simultaneously heats a domestic hot water tank of approximately 200 litres for showers and taps. It solves everything with 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 starts 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 DHW tank and outdoor unit, and providing a fixed quote.

The process takes approximately 90 minutes per standard domestic boiler. We start by shutting off the gas and removing the casing to access the interior. Cleaning the burner and heat exchanger with a wire brush and vacuum cleaner to remove accumulated soot and combustion residue from the year. Checking ignition and flame sensors, replacing if worn. Visual inspection of seals and pipes for signs of corrosion. The best time is October or early November, just before the first significant heating period of the season. This prevents any detected issues from catching you with the heating already in heavy use. It also avoids the usual November rush when everyone tries to fix their heating that won't turn on. Home insurance may deny coverage for incidents. Risk of serious failure if not detected in time. Potential penalty from Community of Valencia inspections.

Official manufacturer warranty (5-7 years) plus our labour coverage. 5-7 years official manufacturer warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day coverage on labour and recommended annual inspections. Common repairs include several. Replacement of electrothermal actuator heads on the manifold that have failed and block a complete circuit, replacement of the circulation pump when it no longer provides sufficient flow, and circuit balancing when there are thermal imbalances between zones. Complete bleeding when there is air in the system. Leaks in embedded piping are the most serious but also infrequent fault. Quality multilayer pipe has a guaranteed lifespan of 50 years.

The price for aerothermal in Cerdanyola del Vallès typically ranges between €188 and €2240. The final figure depends on the property's condition, materials, and working time.
