It starts with calculating the property's thermal loads, sizing the equipment 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 a fixed quote. Air-to-water heat pumps, also known as aerothermal systems, go a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to regulate the indoor temperature, and at the same time heats a domestic hot water tank of approximately 200 litres for showers and taps. It solves everything with a single unit, ideal for detached houses and large homes. Its payback period compared to a traditional gas + air system is 8 to 12 years in the local climate.

The Mediterranean climate of the Costa Blanca perfectly matches a modern heat pump. Mild winters, between 8 and 16 degrees Celsius minimum. 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 produce heating in winter, cooling in summer, and domestic hot water. Their performance is measured by the COP (coefficient of performance), which for a modern 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. Annual gas boiler maintenance, between 90 and 130 euros including certificate. Repair of a simple fault (sensor, valve, pressure switch), 80-180 euros plus parts. Complete replacement of a natural gas boiler with a condensing model, 1,400 euros installation included, depending on brand and power. Boiler maintenance is performed by the same technician who would attend to a serious breakdown. This means they are familiar with the installation. The difference compared to a one-off service contracted by an insurer is noticeable in the appliance's lifespan. A well-maintained boiler lasts 18-20 years. A poorly maintained one breaks down after 8.

For more modern windows with tilt-and-turn profiles and thermal break, the fittings are of better quality but also require maintenance. Lubricating hinges and adjusting closing points every 2-3 years significantly extends their lifespan and prevents air ingress in winter or them becoming too hard to open. 5-7 years official manufacturer's warranty depending on brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day labour coverage and recommended annual inspections. Official manufacturer's warranty (5-7 years) plus our labour coverage.

The price for insulation in Cerdanyola (Mataró) typically ranges between 208 and 2970 euros. The final figure depends on the property's condition, materials, and labour time.
