02 — Scope
What we do at your place
One technician comes to Zemst, one itemised invoice.
Heating engineer requests in Zemst, which spans an area of 42.9 km2 with 23325 inhabitants (2018) in the arrondissement administratif de Hal-Vilvorde, cover condensing gas boiler service, oil boiler service with nozzle and sweep included, and flue sweeping. Residents also request circulation pump replacement, expansion vessel replacement, thermocouple or sensor replacement, and bleeding and balancing the radiator circuit. When phoning, please describe the symptoms of your heating fault so our technician prepares the correct diagnostic tools before travelling.
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.

05 — Questions
Your questions before we arrive
What people in Zemst ask before confirming.
How long for a boiler repair in winter?
The time is given on the phone according to the day's round; a home without heating or hot water comes before a planned service. If a part must be ordered, we give the supplier lead time before you confirm, and we get the system running provisionally when it is safe to do so. See the prices →
Is boiler servicing charged at 6 % or 21 % VAT?
At 6 % if the property is a private dwelling over 10 years old and the invoice is in a private individual's name. That applies to servicing, repairs and boiler replacement. A newer home or business premises is at 21 %. The rate and legal wording appear on the invoice. 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 Zemst: 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 Zemst, and the invoice separates call-out, labour and parts. Request a quote →
