How Does the Aerothermal System Work?

Discover the key elements of the aerothermal system and enjoy efficient and sustainable heating, cooling, and domestic hot water.

How Does the Aerothermal System Work?

Heating

Aerothermal technology provides efficient heating with a heat pump that extracts energy from the outdoor air and distributes it through underfloor heating, radiators, or fan coils.

Cooling

The aerothermal heat pump cools the home in summer by absorbing indoor heat and releasing it outside, ensuring comfort with low energy consumption.

Domestic Hot Water (DHW)

Aerothermal technology generates domestic hot water sustainably, reducing energy consumption by utilizing renewable air energy.

Outdoor Unit

The aerothermal outdoor unit extracts energy from the outside air and converts it into heat, cooling, or hot water, optimizing energy savings and reducing the carbon footprint.

Frequently asked questions

Aerothermal energy is a renewable energy source that uses outdoor air to heat, cool and generate hot water in your home. It works even in very cold conditions, down to -25°C.

For every euro you spend on electricity, aerothermal can generate between 3 and 4 euros of thermal energy. This means savings on your bill of up to 70%, CO₂ emissions reduction of up to 80%, and the convenience of having a single system for heating, cooling and hot water.

Aerothermal extracts energy from outdoor air and converts it into heating, cooling or hot water for your home. It does this through a heat pump that concentrates heat from the air and transfers it to the home system.

In winter, it provides heating through radiators, underfloor heating or fancoils. In summer, the system reverses the process to cool the environment. All this with very reduced electrical consumption compared to traditional systems.

The price varies depending on the size of the home and type of installation, but as a guide it can range from €8,000 for small apartments or houses (less than 80 m² or 2 bedrooms) to €15,000 for large homes (more than 150 m² or 4 bedrooms), all inclusive.

Thanks to bill savings (between 60% and 70%), many customers recover their investment in 4 to 6 years. Additionally, your home gains market value.

No. Although both can cool, aerothermal is much more comprehensive:

  • Provides efficient heating in winter, even at temperatures of -25°C
  • Cools in summer like air conditioning
  • Generates hot water all year round

Furthermore, it consumes 3 to 4 times less electricity than traditional air conditioning.

A fancoil is a device that distributes hot or cold air in the home through a silent fan. It works with hot or cold water from the aerothermal system and can be installed on ceilings, walls or floors.

Among its main benefits are:

  • Provides climate control in winter and summer
  • Allows temperature control per room
  • Modern and discreet design
  • Very quiet operation (less than 25 dB)

DHW stands for Domestic Hot Water, that is, the hot water you use for showering, cooking or washing. With aerothermal, heating water is much more efficient and economical. For example, a family of 4 people pays approximately:

  • €120-150 per month with electric water heater
  • €80-100 with gas
  • Only €30-40 with aerothermal

Plus, you'll have constant and stable hot water.

It depends on the type of system you currently have installed:

  • If you already have air ducts, adaptation to aerothermal is usually simple and quick.
  • If you have individual splits, in some cases they can be reused, although installing a new adapted system is usually more efficient.

A custom design can offer you more comfort and long-term savings.

Yes, aerothermal can work perfectly with existing radiators, especially if they're aluminum or low-temperature ones. Cast iron radiators can also be used, although in some cases it may be advisable to replace them with more efficient models to improve performance.

You can keep most of your current installation and still reduce energy consumption. If you also want summer cooling, you can complement the system with fancoils.
