The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to climate control the home, and simultaneously heats an approximately 200-litre domestic hot water tank for showers and taps. It solves everything with a single unit, ideal for chalets and large homes. Payback compared to a traditional gas + air system is 8-12 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 for a 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 soot and combustion residue accumulated over the year. Checking ignition and flame sensors, replacing them 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 demand of the season. This prevents any issues found during the inspection from catching you with the heating already in heavy use. It also avoids the typical November rush when everyone tries to fix their heating that won't turn on. Home insurance may deny coverage for incidents. Risk of a serious malfunction not detected in time. Possible penalty from inspection by the Generalitat Valenciana.

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

The price for aerothermal heating in Molins de Rei typically ranges between €188 and €2240. The final figure depends on the property's condition, materials, and labour time.
