It starts with calculating the thermal load of the home, 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 finalising the quote. The air-to-water heat pump, also called aerothermal heating, goes a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to condition the home, and simultaneously heats a domestic hot water tank of approximately 200 litres for shower and tap use. It handles everything with a single unit, ideal for chalets and large homes. Payback compared to a traditional gas + air system is 8 to 12 years in this region's climate.

The electrical check includes nominal compressor consumption on startup and at standard operation, insulation check of the wiring, condition of the start-up capacitors (which degrade after seven or eight years), and thermostat verification. Final disinfection with a certified air conditioning product eliminates bacteria, mould, and odours accumulated in the coil. This prevents the characteristic damp smell when you turn on the air conditioning after winter. 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 it's 4-5 degrees. They use it to provide heating in winter, cooling in summer, and domestic hot water. Their efficiency is measured by the COP (Coefficient of Performance), which for a modern unit 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. Certified equipment, installation with official report (boletín), and industrial registration where applicable.
