Aerothermal energy is a technology that harnesses the energy of the outside air to air-condition spaces and produce domestic hot water. It uses a heat pump to extract thermal energy from the air, even at low temperatures, and transfer it to the interior of buildings.

Aerothermal heating works by means of a heat pump that extracts heat from the outside air. This heat is transferred to a refrigerant that circulates in a closed circuit. A compressor then raises the temperature of the refrigerant, and the resulting heat is used to heat the water in the heating system and the building's domestic water.

The main benefits of aerothermal include:

• Energy efficiency: It can generate up to four times more energy than it consumes, significantly reducing energy bills.
• Sustainability: Uses renewable energy from the air, reducing CO2 emissions. 
• Versatility: Provides heating, cooling and domestic hot water with a single system.
• Economic savings: Reduces long-term operating costs due to its high efficiency.
• Low maintenance: Requires less maintenance compared to other traditional heating and cooling systems.

Yes, aerothermal is suitable for a wide variety of dwellings, from apartments to single-family houses. It can be integrated into both new construction and existing buildings.

The cost of installing an aerothermal system can vary depending on the size of the home and the complexity of the installation. Although the initial investment may be higher than other systems, the savings on energy bills and possible incentives and subsidies can quickly offset this investment.

Generally, no special permits are required to install an aerothermal system in a single-family home. However, in communities of neighbors or in areas with specific regulations, it may be necessary to obtain certain permits. It is advisable to consult with local authorities and a professional installer.

The maintenance of an aerothermal system is relatively low. It is recommended that periodic annual inspections be performed by a specialized technician to ensure the correct operation of the system. These checks include cleaning filters, checking refrigerant levels and general inspection of the system.

Aerothermal energy is an environmentally friendly technology. It uses a renewable energy source (air) and significantly reduces CO2 emissions compared to traditional heating and cooling systems based on fossil fuels. This contributes to the fight against climate change and the reduction of the carbon footprint.

Yes, there are subsidies and incentives to encourage the use of renewable energy technologies, including aerothermal. These may include tax deductions, direct subsidies, and financing programs. It is advisable to consult with local authorities and specialized companies for information on available subsidies.
