Aerothermal energy in Barcelona: The evolution of home comfort and energy efficiency
Modern Spain is rapidly transitioning to environmentally friendly energy sources, and aerothermal energy has become the gold standard for private homes and apartments in Catalonia. HVAC - Barcelona offers professional solutions for the design and implementation of air-to-water heat pump systems.
What is aerothermal energy and why is it necessary in Barcelona? It is a technology that extracts up to 75% of the required energy literally from the air, even in winter. The remaining 25% is supplied by the electricity grid. Thus, for every 1 kW of electricity consumed, you get 4 kW of heat. In coastal climates (Maresme, Garraf), where temperatures rarely drop below zero, the system's coefficient of performance (COP) reaches its peak values, making this type of heating the cheapest available.
System configuration options: Monoblocks and Biblocks
We select equipment based on the architectural features of your property in Badalona, Castelldefels or central Barcelona.
Monobloc systems: All components (compressor, heat exchanger, hydraulics) are assembled in a single outdoor unit.
Advantages: Does not take up space inside the house, easy installation, does not require working with a freon circuit inside the room.
Who it is suitable for: Ideal for renovating old houses where the boiler room area is limited.
Bibloc / Split: The system is divided into an external and internal unit.
Pros: The indoor unit (hydraulic module) can have a built-in hot water tank (DHW), which saves space. There is no risk of water freezing in the pipes outside during extreme frosts.
Suitable for: New construction and premium villas in Sant Cugat or Sitges.
Turnkey system configuration: Heating, Cooling and Hot Water Supply
Aerothermal energy from HVAC - Barcelona is not just a boiler replacement, it is the creation of a unified climate ecosystem. We integrate the heat pump with the following consumers:
Water underfloor heating (Suelo Radiante): The most efficient combination. Underfloor heating operates at low temperatures (35°C), allowing the heat pump to operate in the most economical mode. This provides ideal comfort without draughts or dust.
Fan coils: Unlike conventional radiators, fan coils allow the system to operate in cooling mode in summer. This replaces standard air conditioners, providing a milder and healthier climate.
Low-temperature radiators: If your home already has radiators, we will replace them with modern aluminium or steel panels with increased heat exchange area, adapted for aerothermal energy.
Hot water supply (ACS): The system provides hot water for the whole family. We install stainless steel storage tanks with a capacity of 150 to 500 litres.
Solar photovoltaic panels: We configure the automation system so that during sunny hours, aerothermal energy runs on "free" electricity from the sun, accumulating heat in the tanks.
Integration into existing heating systems (hybrid solutions)
One of HVAC - Barcelona's key areas of expertise is the modernisation of existing boiler rooms. If you already have a gas or diesel boiler in Alella or Vilanova i la Geltrú, we can:
Integrate aerothermal energy as the main heat source.
Keep the old boiler as a "peak" heater for very cold nights.
Automate the switch between energy sources depending on electricity and gas rates.
Heating swimming pools with aerothermal energy
In Barcelona, owning a swimming pool is standard. However, without heating, the comfortable season lasts only three months. We install specialised heat pumps or connect the main home unit to the pool circuit via a titanium heat exchanger. This allows us to maintain a temperature of +28°C from April to November at minimal cost.
Installation details and technical specifications
Installing an aerothermal system is a complex engineering process that requires knowledge of hydraulics and electrical engineering.
Design: We calculate the heat loss for each room.
Timeframe: Full installation of an air-to-water system with hot water distribution takes 5 to 10 working days.
Service life: With proper maintenance, the system will last 20-30 years.
Noise: Modern units (e.g. from Daikin or Mitsubishi) are quieter than a standard refrigerator, which is important for densely built-up areas such as Eixample or Gràcia.

Spain's economic policy and aerothermal energy:
Today, the installation of aerothermal systems in Barcelona is encouraged at the national level. Switching from diesel or electric heating to heat pumps entitles you to tax deductions (deducción del IRPF) and direct subsidies. We can help you prepare the technical documentation required to apply for these benefits. By choosing aerothermal energy today, you increase the market value of your property and protect yourself from rising energy prices.

Aerothermal energy: Frequently Asked Questions (FAQ)
1. How much can you really save on heating in Barcelona by installing an aerothermal system? In Barcelona's climate, savings can be up to 70-75% compared to electric radiators and up to 50% compared to modern gas boilers. Thanks to the high average annual COP (usually above 4.0), you use 1 kW of electricity to get more than 4 kW of heat.
2. Do I need to replace my old radiators when switching to a heat pump? Not necessarily. We can install a high-temperature aerothermal system that works with conventional radiators. However, for maximum efficiency, we recommend using low-temperature radiators or underfloor heating, as this reduces the load on the compressor and saves even more energy.
3. Can aerothermal systems be used to cool the house in summer instead of air conditioning? Yes, this is one of the main advantages. If you have fan coils or an underfloor heating system (with an anti-condensation module), the aerothermal system will supply cold water to the system, effectively reducing the temperature in the room.
4. How noisy is the external heat pump unit? Modern installations from leading brands (Daikin, Mitsubishi, Panasonic) have a noise level of between 45 and 55 dB. This is comparable to a quiet conversation or the sound of moderate rain. In night mode, the units operate almost silently, which is important for compliance with municipal noise regulations in Barcelona.
5. Is special permission required to install an aerothermal system in an apartment building? If the outdoor unit is located on the façade or roof, the consent of the residents' association (Comunidad de vecinos) is required. We can help you prepare a technical justification for such cases, confirming compliance with noise and aesthetic standards.
6. How long does it take for an aerothermal system to pay for itself in Spain? Taking into account current electricity and gas prices, as well as the possibility of receiving government subsidies (Fondos Next Generation), the average payback period for the system is 4 to 7 years. With a service life of 20-25 years, this is an extremely profitable investment.
7. Does aerothermal energy work at sub-zero temperatures? Yes, modern heat pumps remain operational at temperatures as low as -20°C or -25°C. Although such temperatures are not common in Barcelona, this ensures that even on the coldest winter night in the foothills of the Pyrenees, your home will be warm.
8. Can aerothermal energy be combined with solar panels? It's a perfect match. Solar panels generate free electricity, which aerothermal energy converts into free heat. We configure the control system so that the water in the DHW tank is heated during peak solar activity.
9. What maintenance does the system require? Maintenance is minimal: annual system pressure check, cleaning of internal and external unit filters, and checking the condition of the freon circuit. We provide regular maintenance services under contract to extend the warranty.
10. Can aerothermal energy be used to heat water in a swimming pool? Yes, we connect the external unit to the pool's heat exchanger. This allows the water to be kept warm (+26..+28°C) from the beginning of April to the end of October, using 5 times less energy than electric heaters.
