It starts with calculating the thermal loads of the home, sizing the system 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 price. The air-to-water heat pump, also known as aerothermal energy, goes a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to air condition the home, and at the same time heats a domestic hot water tank of approximately 200 litres for shower and tap use. It resolves everything in a single unit, ideal for chalets and large homes. Its payback compared to a traditional gas + air system is 8 to 12 years in the local climate.

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 produce heating in winter, cooling in summer, and domestic hot water. Its efficiency 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. Programmable and smartphone-connected thermostats like Tado, Nest, or Honeywell, installation and configuration. In holiday rental properties, this saves a lot of money because you can remotely turn off the heating when tenants leave the flat. The typical problem occurs when you go to turn on the boiler or underfloor heating after eight months of disuse and it doesn't respond. The pump has seized, the expansion vessel has lost pressure, the thermostat has become deconfigured. We see this every November.

For more modern tilt-and-turn windows with thermal breaks, the hardware is of better quality but also requires maintenance. Lubricating the hinges and adjusting the locking points every 2-3 years significantly extends their service life and prevents air leakage in winter or makes them too difficult to open.
