Heating in Catalonia: boilers, radiators and underfloor heating
Catalunya Servei installs and services heating systems — condensing boilers, radiators, underfloor heating and communal plant rooms — with in-house, RITE-certified installers.
Boiler installed from €1,800
Which boiler should you install in Catalonia in 2026?
A 25-30 kW condensing boiler from a reference brand (Saunier Duval, Junkers, Vaillant): it uses up to 30% less than an old sealed unit and is the only type EU regulations allow to be installed.
If your boiler is over 12-15 years old, replacing it often beats another repair: the efficiency gain pays for the swap within 3-4 winters. And if you're considering leaving gas behind, see our aerothermal page: we compare both options with your real consumption figures.
Radiators vs. underfloor heating: which heats better?
Quick answer: Radiators are cheaper and quick to respond; underfloor heating is more comfortable and cheaper to run long-term, but only makes sense in new builds or full renovations.
| Criterion | Radiators | Underfloor heating |
|---|---|---|
| Indicative price (90 m²) | €2,500 – 4,000 | €6,000 – 9,000 |
| Comfort | Heat by zones | Uniform temperature, no dry air |
| When to choose it | Lived-in home, tight budget | New build, full renovation, heat pumps |
With an aerothermal heat pump, underfloor heating is the winning combination: it runs at low temperature, exactly where the heat pump performs best.
