04 — Scope
What we do at your place
One technician comes to Oud-Heverlee, one itemised invoice.
In the municipality of Oud-Heverlee, spanning 31.1 km2 for 11099 inhabitants in the arrondissement administratif de Louvain, heating engineer call-outs address seasonal boiler checks and cold-weather breakdowns. Technicians handle oil boiler service with nozzle and sweep included, flue sweeping, circulation pump replacement, and expansion vessel replacement. When calling, a resident should describe the symptoms, such as an unlit burner or cold radiators, so fault diagnosis or thermocouple or sensor replacement can be prepared.
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.

06 — Questions
Your questions before we arrive
What people in Oud-Heverlee 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 →
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. See the prices →
Conventional gas boiler service (certificate included) in Oud-Heverlee: 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 Oud-Heverlee, and the invoice separates call-out, labour and parts. Request a quote →
Do you really cover Oud-Heverlee (3050)?
Yes. Oud-Heverlee is in our area, Flemish Brabant included. The nearest municipality we also cover is Bertem, 3.5 km away. The slot is confirmed by phone before the technician leaves. See the prices →

How can residents reach the heating engineer and what details should they provide?
Reach FUSE SERVICES on 02 886 10 49 or by e-mail at info@fuse-services.be. State your boiler type and observed fault symptoms on the phone before the technician leaves so fault diagnosis can be properly arranged. See the prices →
Is the price of a replacement part stated before an order is placed?
Yes, no part is ordered without its price being stated to the customer beforehand. The company upholds this written promise alongside stating labour amounts over the phone before the heating engineer leaves for the visit. Request a quote →
What intervention is carried out if the radiators stay cold?
A heating engineer undertakes fault diagnosis, followed by bleeding and balancing the radiator circuit or circulation pump replacement if water circulation is blocked. Boiler heat exchanger replacement or expansion vessel replacement may also be completed when required. See the prices →
Are the sub-localities of Oud-Heverlee such as Blanden and Haasrode also covered?
Yes, every sub-locality of Oud-Heverlee is covered, including Blanden, Haasrode, Vaalbeek, and Sint-Joris-Weert. Technicians handle condensing gas boiler service, oil boiler service, and flue sweeping across every section of the commune. Request a quote →
