01 — Scope
What we do at your place
One technician comes to Chastre, one itemised invoice.
Our heating engineer interventions address households across the 31.3 km2 of Chastre, a municipality of 7592 inhabitants in the arrondissement administratif de Nivelles. Routine work includes a conventional gas boiler service with certificate included, a condensing gas boiler service, or an oil boiler service with nozzle and sweep included. Technicians also carry out expansion vessel replacement, flue sweeping, or bleeding and balancing the radiator circuit. When calling, please have your boiler make and symptoms ready for the technician.
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 Chastre 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 →
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. 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 Chastre: 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 Chastre, and the invoice separates call-out, labour and parts. Request a quote →
Do you really cover Chastre (1450)?
Yes. Chastre is in our area, Walloon Brabant included. The nearest municipality we also cover is Walhain, 4.0 km away. The slot is confirmed by phone before the technician leaves. See the prices →
Which postcode serves Chastre and does your heating engineer service cover it?
Chastre uses postcode 1450. FUSE SERVICES provides complete coverage across the entire municipality under this postal code 24 hours a day, 7 days a week. Request a quote →
What will an intervention cost and how is the amount confirmed?
The amount is stated on the phone before the technician leaves. Labour surcharges apply for evening, night, Sunday, and holiday call-outs, and no service is invoiced without a certificate handed over. See the prices →
What is included in a fault diagnosis visit?
A fault diagnosis covers the call-out and 1 h of on-site diagnostic testing. The heating engineer checks your installation, identifies any defective part, and explains what repair is required. Request a quote →
