04 — Scope
What we do at your place
One technician comes to Walhain, one itemised invoice.
Across an area of 37.9 km2 with 7167 inhabitants in the arrondissement administratif de Nivelles, heating engineer work in Walhain addresses varied domestic setups. Interventions include fault diagnosis, oil boiler service with nozzle and sweep included, condensing gas boiler service and conventional gas boiler service with certificate included. Residents also request thermocouple or sensor replacement, expansion vessel replacement, circulation pump replacement or bleeding and balancing the radiator circuit. When telephoning, having the symptoms of the breakdown clearly described allows the technician to prepare the required parts.
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.

Your questions before we arrive
What people in Walhain 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 →
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. 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 Walhain: 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 Walhain, and the invoice separates call-out, labour and parts. Request a quote →
