Frequently asked questions

In an emergency we commit to being with you within 2 hours in the Brussels Region. For Wallonia and Flanders, the time depends on the distance but stays within the day. For planned work (servicing, chimney sweeping, a quote), we arrange an appointment to suit you.

Yes. Chauffitherm is available 7 days a week, weekends and public holidays included. A €30 surcharge applies to work at night, at weekends and on public holidays — it is stated before the work, never afterwards.

Turn off the gas and electrical supply to the boiler, ventilate the room and do not attempt anything inside the appliance. If you smell gas, leave the property and call 0800 65 065 immediately (the Belgian gas emergency number) before contacting us.

Brussels and its 19 municipalities, Wallonia (Walloon Brabant, Liège, Namur, Hainaut) and Flanders (Flemish Brabant, Antwerp and the surrounding area). The travel charge is a flat €35, whatever your address within that area.

€35 for travel and diagnosis, then from €80 for the first hour's labour. Spare parts are charged on top. The total is always given to you before we begin any repairs.

Yes, the quote is free and without obligation. If you turn the quote down after our visit, only the €35 for travel and diagnosis remains due.

No, all prices shown on the site exclude VAT. The VAT in force is applied to the final invoice in accordance with Belgian law. For a home more than 10 years old, a reduced rate of 6% may apply to the labour.

Payment by bank transfer against an invoice, or on site at the end of the visit. Contact us directly if you would like to discuss payment arrangements that suit your situation.

None. Travel is a flat €35, labour is stated in advance and parts are agreed with you before they are replaced. Nothing appears on the invoice that has not been stated.

Yes. In the Brussels Region, servicing is compulsory every 2 years for a gas boiler and every year for an oil boiler. In Wallonia it is every 3 years for gas and every year for oil. In Flanders, every 2 years for gas and every year for oil.

Yes, an official periodic inspection certificate is issued at the end of every service. Your insurer requires it in the event of a claim, and the notary asks for it when the property is sold. Keep it safe.

Cleaning the heat exchanger and the burner, checking combustion and flue gases, checking gas tightness, checking the expansion vessel and the pressure, optimal adjustment, then handing over the signed report and the legal certificate.

Yes. The annual contract gives you priority in the event of a breakdown, preferential pricing on spare parts and an automatic reminder before the legal deadline. The amount is set by quotation depending on your system.

Yes. In the Brussels Region, the flue of a gas boiler must be swept every 2 years, and every year for oil, wood or coal. The sweeping certificate is essential in the event of a fire claim.

We work on all the major brands on the Belgian market: Bulex, Vaillant, Junkers, Viessmann, Atlantic and Remeha, as well as most other common brands.

Beyond 15 to 20 years, or when the cost of repairs exceeds half the price of a new boiler, replacing becomes the better value. A recent condensing boiler uses 25 to 30% less. We give you an honest recommendation after the diagnosis — with no hard sell.

Replacing a wall-hung boiler generally takes a day. A full installation with changes to the pipework or a move to condensing can take 2 to 3 days. The exact schedule is given to you with the quote.

Power flushing removes the metal sludge built up in the radiators and the heating circuit. It is recommended if your radiators heat poorly at the bottom, make noise, or if your system is more than 10 years old and has never been treated. It can recover up to 15% in efficiency.

Yes: leaks, replacing taps and mixers, electric water heaters, connections, leak detection and bathroom work. It is all done by the same tradesman, with the same transparent prices.

It depends on the blockage: a mechanical snake for short waste runs, high-pressure jetting for risers and outside inspection chambers. For a recurring blockage, we offer a camera inspection to identify the real cause (roots, subsidence, limescale build-up).

No, our methods are matched to the material and the age of the pipework. We do not use harsh chemical products, which attack seals and pipes over the long term.

Yes. Labour is guaranteed and spare parts carry the manufacturer's warranty. If the same problem comes back, we return without charging travel again.
