Bulex is the historic Belgian brand of the Vaillant group — a fixture in Brussels homes for decades. Technically identical to Vaillant boilers, the Bulex models (Themaclassic, Thema Condens, eFIT, Senso) benefit from a well-stocked supply of original parts, which makes for fast visits and lasting repairs.
Chauffitherm works across the whole Bulex range in Brussels and throughout Belgium. Our engineers know the quirks of these boilers — electronic diagnostics, replacement of sensitive parts, combustion settings — so the job gets done properly on the first visit.
What our Bulex expertise covers
- Full diagnosis on Bulex boilers (Themaclassic, Thema Condens, eFIT, Senso and more)
- Replacement with guaranteed original Bulex / Vaillant parts
- Annual servicing with an official certificate accepted by insurers
- Emergency callout 7 days a week — same-day visit in most cases
Bulex in Brussels: a local brand, local engineers
The Bulex boiler is the most common one in Brussels apartment blocks and family homes. Our engineers know the models most often found in the region inside out — in particular the Themaclassic, still very common in Brussels flats built between the 1990s and 2010. That local knowledge means we arrive prepared, carrying the most requested parts, and fix your fault in a single visit.
Transparent pricing, no surprises
