The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to regulate the home's temperature, and simultaneously heats a domestic hot water tank of approximately 200 litres for showers and taps. It handles everything in a single unit, ideal for large houses and properties. Its payback compared to a traditional gas + air system is 8 to 12 years in the local climate. A complete aerothermal installation is a significant project. It begins 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 domestic hot water tank and outdoor unit, and providing a fixed quote.

The electrical check includes the compressor's nominal power consumption during start-up and operation, insulation resistance of the wiring, condition of the start-up capacitors (which degrade after seven or eight years), and thermostat verification. The final disinfection with a certified air conditioning product eliminates bacteria, fungi, and odours accumulated in the coil. This prevents the characteristic musty smell when you turn on the air conditioning after winter. The real economic savings from maintenance are easy to calculate. A serious air conditioning breakdown in August, involving compressor replacement or significant leak repair, costs several times more than annual maintenance over 5 consecutive years. Our data from regular clients confirm that units with scheduled maintenance last 40 percent longer than those without any maintenance. The Mediterranean climate of the Costa Blanca is perfectly suited for a modern heat pump. Mild winters, with minimum temperatures between 8 and 16 degrees. Hot summers, but not extreme on the coast. Heat pumps extract energy from the outside air even when temperatures are as low as 4-5 degrees. They use this energy 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 ranges between 3.5 and 4.5. This means it produces 3.5 to 4.5 kilowatts of heat for every kilowatt of electricity consumed.
