The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to climate control 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 large houses and villas. Its amortization 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 thermal loads of the home, sizing the unit according to actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the DHW tank and the outdoor unit, and a fixed quote.

For a property on the Costa Blanca with existing underfloor heating that has started to malfunction (cold zone not heating, leak, circulation noise), diagnosis requires specific tools. A thermal imaging camera to identify non-functioning circuits, an electronic leak detector to locate loss points without breaking the floor. Manometers to check circuit pressures. In most cases, we can diagnose and repair without lifting the entire floor. 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. Complete bleeding when there is air in the system. Leaks in embedded pipes are the most serious but also infrequent fault. Quality multilayer pipe is guaranteed to last 50 years. The Mediterranean climate of the Costa Blanca is perfectly suited to a modern heat pump. Mild winters, between 8 and 16 degrees minimum. Hot summers, but not extreme on the coast. Heat pumps extract energy from the outdoor air even when it's 4-5 degrees. They use it to produce heating in winter, cooling in summer, and domestic hot water. Their efficiency is measured by the COP (Coefficient of Performance), which for a modern heat pump in this climate is between 3.5 and 4.5. This means it produces 3.5 to 4.5 kilowatts of heat for every kilowatt of electricity consumed.

5-7 years manufacturer's official warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day coverage on labour and recommended annual inspections. Official manufacturer's warranty (5-7 years) plus our labour coverage. Junkers (Bosch) is a second option with similar quality and slightly more competitive prices. The Cerapur Excellence Compact range is robust and efficient.

The price for aerothermal heating in El Putxet i el Farró typically ranges between €188 and €2240. The final figure depends on the property's condition, materials, and the time required. We always provide a fixed quote before starting. Saunier Duval offers a very good quality-price ratio, with the ThemaPlus Condens range as a benchmark for medium-sized apartments and the Renova Condens for larger homes.
