The periodic check in Brussels

In the Brussels-Capital Region, boilers are subject to a periodic check under the heating energy performance rules. How often depends on the fuel: oil boilers are checked more often than gas boilers.

The check covers cleaning, the safety devices, a combustion measurement and the flue. The engineer compares the results with the Brussels requirements and adjusts the boiler when needed.

You receive the attestation with the measurements. Keep it: Brussels Environment, your insurer or your landlord may ask for it. The engineer also tells you when to plan the next check.

Combustion analysis during a boiler service

Servicing wall-hung gas boilers

Most people in Brussels heat with gas through a wall-hung boiler, often in the kitchen or bathroom of a flat. The service takes about an hour and needs no works.

The engineer cleans the burner and checks the electrodes, empties and rinses the condensate trap, checks the fan, the safety devices, the gas joints, the circuit pressure and the expansion vessel. Where the water is hard, he also checks the hot water side.

He ends with the combustion analysis and a check of the flue, often a balanced flue on the façade or a shared duct in blocks of flats.

Servicing oil boilers

In older houses in Uccle, Woluwe, Forest or Ganshoren, oil boilers still run in the cellar. They need a fuller service than gas: the combustion chamber is brushed, the nozzle and the filter are replaced and the burner is cleaned.

The engineer then adjusts the burner and measures the combustion. He points out anything he sees on the tank or the supply line, such as a trace of leakage or corrosion.

Sweeping the chimney is a separate job, also compulsory. If you are thinking of replacing the oil boiler, the engineer can explain the options and the Brussels grants during the same visit.

Servicing heat pumps

Heat pumps are spreading in Brussels, in renovations as well as new homes. They have no burner, but regular servicing is still needed to keep the efficiency up.

The engineer cleans the outdoor coil, checks the fan, the condensate drain, the strainers of the water circuit, the hot water production and the settings. In a courtyard or on a terrace, he also checks that the unit breathes freely and does not disturb the neighbours.

Depending on the amount of refrigerant, a periodic leak check is required. We tell you what applies to your appliance.

What to know in Brussels

In Brussels the yearly service is in principle paid by the tenant, unless the lease says otherwise. The attestation serves as proof at the end of the lease.

For a shared plant room, the syndic organises the service. We plan it with him and let the residents know. Brussels water is hard and scales up plate exchangers, so the hot water is checked during the service.

Parking can be tight: a free spot in front of your door or access to the building garage makes the visit easier and keeps it on time.

How to book

Choose a slot online or by phone, giving the make and the fuel; the price is given at that moment. If you have a code on the display or a recurring fault, tell us too.

The visit itself covers cleaning, checks, adjustments and the combustion analysis. If a wear part needs replacing, the engineer tells you the cost and you decide.

The attestation is handed over at the end of the visit, with the job sheet, followed by the invoice. We can remind you every year when the next service is due.

Frequently asked questions

How often must a boiler be serviced in Brussels?

Brussels rules set the frequency by fuel, shorter for oil than for gas. The engineer writes the date of the next check on your attestation.

How much does the service cost?

The price depends on the type of boiler and is given when you book, by phone on 0477 03 88 98 or online.

Will I receive an attestation?

Yes, at the end of every service, with the results of the combustion analysis.

Do you service every make?

Yes: Vaillant, Bulex, Viessmann, Buderus, Remeha, Junkers, Saunier Duval, ACV, Atag, Intergas and the others.

Can you service all the boilers of a building?

Yes, we organise the service of several flats or a shared plant room with the syndic, with one attestation per appliance.

How long does the visit take?

About an hour for a wall-hung gas boiler, a little longer for an oil boiler or a plant room.
