Installation and fitting of HVAC equipment in Barcelona

Installation of aerothermal systems for heating swimming pools in Barcelona:
Swimming season all year round


Owning a swimming pool in Barcelona or its suburbs (e.g. Castelldefels, Sitges or Sant Cugat) is a great pleasure, but unfortunately it is limited to only 3-4 months of the year. Even in sunny Catalonia, the water in outdoor pools remains comfortable only from mid-June to September. HVAC Barcelona (www.hvac.barcelona) offers a solution to this problem: the installation of specialised aerothermal heat pumps for heating swimming pools.

 

 


How does aerothermal energy work for swimming pools?


The principle of operation is similar to that of domestic aerothermal energy: the heat pump takes energy from the surrounding air and transfers it to the pool water via a titanium heat exchanger. This is 5-6 times more efficient and cheaper than electric flow heaters.


Advantages for villa owners in Barcelona:
Extended season: You can comfortably use your pool from April to November. The water will remain at a stable 26-28°C regardless of night-time temperature drops.
Cost-effectiveness: Thanks to its high COP (up to 6.0), the system consumes a minimum amount of electricity. In sunny Barcelona, the efficiency of such installations reaches its maximum.
Durability in a maritime climate: We use models with titanium heat exchangers that are resistant to chlorine and salt water (if you have a salt electrolysis system installed). This is critical for facilities in Gava Mar and Maresme.


Specifics of equipment installation in Catalonia


HVAC Barcelona specialists perform a full cycle of work to integrate heating into the existing filtration system:
Power selection: We take into account the volume of the pool, the presence of a protective cover (solar blanket) and the windiness of the site in your location. An incorrectly selected pump simply will not be able to heat a large amount of water in windy weather on the coast.
Bypass line: We install a special bypass unit that allows you to regulate the water flow through the heater and turn it off for maintenance without stopping filtration.
Electrical safety: Installation of specialised protection and grounding in accordance with Spanish standards for wet areas.
Automation: Integration with a smart home system or installation of Wi-Fi modules. You can turn on the heating for your pool in Sant Just Desvern while you are in the centre of Barcelona, so that the water is at the perfect temperature when you arrive.


Why choose HVAC Barcelona?

High-quality materials: We use high-pressure PVC pipes and fittings that are resistant to UV radiation and chemicals.
