Installation of underfloor heating systems in Barcelona:
Maximum comfort and energy efficiency
The issue of effective heating in Barcelona is more acute than it may seem at first glance. Traditional radiators do not always cope with the high humidity and specific architecture of Catalan houses. HVAC Barcelona (www.hvac.barcelona) offers the installation of underfloor heating systems — the most advanced heating method, which ensures even temperature distribution and aesthetic freedom in interior design. We provide turnkey design and installation services in Barcelona and the surrounding regions, complying with strict European quality standards.
Why is underfloor heating the best solution for Barcelona?
Underfloor heating works on the principle of radiation rather than convection. This is crucial in high-ceilinged apartments in the Eixample district or villas in Sant Cugat. Unlike radiators, which heat the air near the ceiling, underfloor heating concentrates heat in the living area (1.5–2 metres above the floor).
Key benefits for residents in our region:
Combating dampness: In coastal areas such as Poblenou or Gava Mar, floors often remain cold and damp due to the proximity of groundwater or the specific characteristics of the foundations. Underfloor heating completely dries out the base, preventing mould and mildew from forming under the floor covering.
Savings of up to 20%: The system operates with a low-temperature heat transfer fluid (35–45°C), which is ideal for aerothermal energy. This significantly reduces electricity bills in Spain.
Aesthetics and space: You get rid of bulky radiators, which is especially relevant for the panoramic glazing often found in new buildings in Diagonal Mar.
Types of systems we install
HVAC Barcelona has the technical base and licences to install two main types of underfloor heating:
1. Water underfloor heating (Suelo Radiante por Agua)
This is the most popular and economical system for private homes and major apartment renovations in Barcelona.
Specific features: Cross-linked polyethylene (PEX) pipes are laid on a layer of thermal insulation and covered with screed.
Heat source: We integrate water underfloor heating with gas boilers or heat pumps (aerothermal energy).
Cooling function: The unique advantage of aerothermal energy in
Barcelona — in summer, cold water can be run through the pipes, which lowers the temperature in the house by 3–5°C without draughts from the air conditioner.
2. Electric underfloor heating
The best option for local installation (bathroom, kitchen) or in cases where it is impossible to raise the floor level for a full screed.
Types: Heating mats or cable.
Advantages: Quick installation and instant heating. Ideal for flats in the centre of Barcelona undergoing cosmetic repairs.
Professional installation and stages of work
Underfloor heating installation is a hidden job, and mistakes can be very costly. At HVAC Barcelona, we follow a strict protocol:
Preparation of the base: We guarantee a perfect level and the installation of damper tape around the perimeter of all walls in Barcelona to compensate for the thermal expansion of the screed.
Thermal insulation: Use of high-density polystyrene foam mats. We do not allow heat to escape down to the neighbours or into the foundation.
Hydraulic testing: Before pouring concrete, the system must be pressure tested at 6 bar for 24 hours. We issue a test report confirming the tightness of the system.
Installation of the manifold group: Installation of the "heart" of the system — a distribution cabinet with a pump-mixing unit and automation that allows you to regulate the temperature in each room separately (zoning).
Service area and warranty
We work throughout the Barcelona Area: from the historic centre to remote urbanisations in Maresme and Sitges.
Our company has all the necessary licences in Spain to carry out heating work. We provide a long-term warranty for the integrity of the pipes and the correct operation of the automation.
