Vaillant is one of Europe's benchmarks in condensing heating. Founded in Germany in 1874, the brand equips millions of Belgian homes with boilers known for their reliability and high energy efficiency. But a premium boiler needs servicing and repairs carried out by trained, approved engineers.
At Chauffitherm we work exclusively with original Vaillant parts and diagnostic tools suited to the range. The result: repairs that last and services that protect the manufacturer's warranty.

Preventive servicing of your Vaillant boiler following the manufacturer's protocol. An official certificate is issued at every visit — required by your insurer.
Original Vaillant parts

Why we insist on original Vaillant parts
Vaillant condensing boilers use electronic components calibrated to work together. Using generic parts can cause malfunctions, void the manufacturer's warranty and shorten the life of your system. We use only approved original parts — Vaillant control boards, heat exchangers, valves, temperature sensors and pumps.
Every repair is covered by the warranty on the parts fitted. The price is given before any work starts.

Are you genuinely Vaillant approved to work in Brussels?
Yes. Chauffitherm is approved on the Vaillant brand, which means our engineers are trained to the manufacturer's standards and have the diagnostic tools specific to the ecoTEC, ecoTEC Plus and atmoTEC ranges. We have access to original parts and can carry out updates to the electronic modules.
How long does a well-maintained Vaillant boiler last?
A Vaillant condensing boiler serviced every year can run for between 15 and 20 years. The annual service picks up wear on components before it causes a breakdown, keeps efficiency at its best and meets the conditions of the manufacturer's warranty. Contact us to book your service.
