02 — Scope
What we do at your place
One technician comes to Merchtem, one itemised invoice.
In Merchtem, an area of 36.7 km2 home to 16294 inhabitants in the arrondissement administratif de Hal-Vilvorde, heating engineer call-outs involve oil boiler service with nozzle and sweep included, condensing gas boiler service, and flue sweeping. Residents also call for expansion vessel replacement, thermocouple or sensor replacement, or circulation pump replacement. When telephoning, having your boiler type ready assists the team, knowing no part is ordered without its price being stated and no replacement proposed when a priced repair will do.
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 Merchtem 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 →
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 →
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. See the prices →
Conventional gas boiler service (certificate included) in Merchtem: 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 Merchtem, and the invoice separates call-out, labour and parts. Request a quote →

What is included in a fault diagnosis?
A fault diagnosis covers the call-out plus 1 h of labour on site to inspect the heating equipment. Technicians identify the issue, and no boiler replacement is proposed when a priced repair will do. See the prices →
What heating engineer work is done when radiators stay cold?
