Air-source heat pump FAQs

An air-source heat pump is a technology that extracts the energy contained in the outside air and transfers it to your home. With a single unit you get heating in winter, cooling in summer and domestic hot water all year round.

Most of the energy it uses comes from the air, so it consumes far less electricity than a conventional system. Find out how we work on our air-source heat pump page.

An air-source heat pump produces several times more heat energy than the electricity it consumes, so the savings compared with a gas or oil boiler or an electric water heater are usually very significant. The exact figure depends on your home's insulation, the system you replace and your consumption habits. Here are more tips to reduce your electricity and water bills.

Yes. Today's units keep working at outdoor temperatures below zero, although their performance drops as the temperature falls. In Andalusia and the Region of Murcia, with their mild winters, air-source heat pumps work in very favourable conditions and deliver high performance all year round.

Yes, the heat pump is reversible: in winter it brings heat in and in summer it removes it from your home. Cooling can be distributed through fan coils, underfloor cooling or ducts, depending on the installation. That way you cover heating, cooling and hot water with a single system.

If you are interested in cooling with solar energy, we explain whether you can run air conditioning on solar panels.

Yes, and it is the most efficient combination. An air-source heat pump needs some electricity to run, and if that electricity is generated by your solar panels, your heating, cooling and hot water run on 100% renewable energy.

At SolQuality we design combined air-source heat pump and solar PV installations to maximise your savings. Discover the advantages of solar self-consumption and find answers in our frequently asked questions about solar panels.

An air-source heat pump performs best with low-temperature systems such as underfloor heating, fan coils or low-temperature radiators. It can also work with conventional radiators, although it is advisable to check their sizing or choose a high-temperature unit.

We assess your current installation and recommend the most suitable option.

Yes. An air-source heat pump can completely replace a gas, oil or butane boiler, in many cases using the existing heating circuit. As well as cutting costs, you eliminate combustion in your home, the fuel tank and the inspections associated with the boiler.

When switching from gas to electricity it is worth reviewing your contract: check our electricity tariffs.

The installation consists of an outdoor unit, similar to that of an air conditioner, and an indoor unit with a hot water cylinder. The outdoor unit is placed on a terrace, in the garden, on the roof or on the façade, and the indoor unit in a utility room, garage or plant room.

During the technical visit we check the available space and suggest the best location.

Today's units are quiet, with a noise level comparable to that of a modern air conditioning outdoor unit. Correct positioning and proper installation, with anti-vibration mounts, prevent any nuisance for you and your neighbours.

In a single-family home, installation is usually completed in a few days, depending on the complexity of the project and whether the existing circuit is reused. Before we start, we give you a clear schedule so you always know what will be done and when.

You can see examples of our work in projects.

Maintenance is simple. A periodic check by a technician is recommended to inspect the circuit, the filters and the correct operation of the unit, as well as keeping the outdoor unit clean and free of obstructions. With this care, the system maintains its efficiency for many years.

With correct installation and proper maintenance, an air-source heat pump can run for many years with stable performance. We work with leading manufacturers and inform you of the warranty conditions for each unit before installation.

It is also an improvement that increases the value of your home.

Yes. An air-source heat pump can heat your pool water and extend the swimming season with very low consumption. Combined with solar panels, it is one of the most economical ways to heat a pool.

It is a very common solution in our air-source heat pump installations in Marbella.

There are grants and tax benefits for renewable energy installations and energy efficiency improvements, which vary depending on the autonomous community, the municipality and the current call for applications. At SolQuality we inform you of the aid available in your case and take care of the paperwork.

If you also install solar PV, check the personal income tax (IRPF) deduction for installing solar panels and the guide to solar self-consumption subsidies in 2026.
