01 — Scope
What we do at your place
One technician comes to Molenbeek-Saint-Jean, one itemised invoice.
Across an area of 6.0 km2 with 97979 inhabitants, heating engineer tasks in Molenbeek-Saint-Jean frequently require fault diagnosis, bleeding and balancing the radiator circuit, or an expansion vessel replacement. Technicians also carry out circulation pump replacement, boiler heat exchanger replacement, or thermocouple or sensor replacement. When calling, residents in the arrondissement administratif de Bruxelles-Capitale should state their boiler type, whether a conventional gas boiler or an oil boiler, so the correct intervention is prepared.
Oil boiler service
Nozzle replacement, combustion chamber cleaning, flue sweeping where needed, burner adjustment and flue gas measurement. Mandatory annual certificate.
Boiler repairs
Error code, lockout, no hot water, burner that will not start. Fixed-fee diagnosis, then repair amount stated before any part is ordered.
Pump, vessel, valve
Replacement of the parts behind pressure and circulation faults: pump, expansion vessel, safety valve, automatic air vent. Part reference shown on the invoice.
Radiators and thermostats
Bleeding and balancing the circuit, thermostatic valve replacement, fitting a room or smart thermostat. Connection to the existing circuit where needed.
Boiler replacement
When repairing no longer makes sense: written quote for a condensing boiler, removal of the old one, connection, commissioning and first certificate.

06 — Questions
Your questions before we arrive
What people in Molenbeek-Saint-Jean ask before confirming.
What guarantee covers a replaced part?
New parts are covered by the two-year legal conformity guarantee under Belgian law, plus the manufacturer's warranty where it is longer. The labour guarantee is written on the invoice. An identical fault on the same part within that period is redone without a diagnosis fee. See the prices →
What should I prepare before the heating engineer's visit?
Clear access to the boiler and gas meter, and find the last service certificate and the manual if you have them. A WhatsApp photo of the rating plate and the error code lets us bring the right part and often avoid a second visit. Request a quote →
Breakdown tonight: emergency or appointment tomorrow?
A smell of gas is an emergency for Sibelga or 112, not for a heating engineer. For a boiler that has stopped without danger, next-day working-hours appointment costs the normal fee; an evening or weekend visit carries the surcharge stated on the phone. We give you both options and the price of each. See the prices →
Conventional gas boiler service (certificate included) in Molenbeek-Saint-Jean: how much does it cost?
The Belgian market in 2026 sits between €100 and €135 excluding VAT for conventional gas boiler service (certificate included), night and weekend surcharges excluded. This is not our own rate card: your exact amount is announced on the phone before the technician leaves for Molenbeek-Saint-Jean, and the invoice separates call-out, labour and parts.
