02 — Questions
Your questions before we arrive
What people in Genappe ask before confirming.
Can the service fee quoted go up on site?
Not for the service itself: the fee depends on the boiler type you gave and includes cleaning, checks, combustion analysis and certificate. Only a flue sweep or a worn part found on site is added, and only after the engineer has shown and priced it to you. 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 Genappe: 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 Genappe, and the invoice separates call-out, labour and parts. Request a quote →
Do you really cover Genappe (1470)?
Yes. Genappe is in our area, Walloon Brabant included. The nearest municipality we also cover is Villers-la-Ville, 6.7 km away. The slot is confirmed by phone before the technician leaves. See the prices →
What is done when the radiators stay cold in Genappe?
Bleeding and balancing the radiator circuit restores even heat distribution across the home. When pipework remains cold despite venting, a circulation pump replacement or a fault diagnosis identifies and resolves the mechanical failure. Request a quote →
How can residents reach the company and what details should be given by phone?
Call 02 886 10 49 day or night, or send an e-mail to info@fuse-services.be. Callers should state the apparent problem, such as burner cut-outs or leaking vessels, and the amount is stated on the phone before the technician leaves. See the prices →
What does a boiler service include and what paperwork is handed over?
A conventional gas boiler service includes an official certificate, while an oil boiler service includes the nozzle and sweep. Furthermore, no service is invoiced without a certificate handed over upon completion of the inspection. Request a quote →
Are the sub-localities of Genappe covered as well?
Every sub-locality is covered, including Baisy-Thy, Bousval, Glabais, Houtain-le-Val, Loupoigne, Vieux-Genappe, and Ways. The heating engineer service attends addresses throughout all these sectors within the commune across 24 hours a day, 7 days a week. See the prices →
What does a fault diagnosis cover during a heating visit?
A fault diagnosis covers the call-out plus 1 h of systematic testing on site. This allows the heating engineer to test parts, with no part ordered without its price being stated beforehand. Request a quote →

04 — Scope
What we do at your place
One technician comes to Genappe, one itemised invoice.
In the municipality of Genappe, which covers an area of 28.7 km2 with 15353 inhabitants, domestic heating setups encounter faulty components over time. Practical tasks range from a circulation pump replacement or bleeding and balancing the radiator circuit to an expansion vessel replacement or thermocouple or sensor replacement. When calling, describing whether a fault diagnosis is needed or specifying boiler symptoms helps the heating engineer prepare before departure.
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.
