How often should a wood or pellet boiler be serviced?

Have a central heating boiler that burns wood or pellets serviced every year by a certified technician. In Flanders (Belgium) this is required by law.

Solid fuel leaves ash and soot in the boiler and flue. An annual service keeps combustion clean and efficient and limits the risk of carbon monoxide. You also have the chimney swept separately.

1. Book a yearly appointment with a technician certified for solid fuel
2. Clear the boiler and the area around it
3. Have cleaning, inspection and adjustment carried out
4. Keep the service certificate

60 to 120 minutes.

Flanders (Belgium): a central heating boiler that burns solid fuel, such as wood or pellets, must be serviced every year by a certified technician, whatever its output.

Wallonia and Brussels also require an annual inspection of a solid-fuel boiler (Walloon decree of 29 January 2009, periodic PEB inspection in Brussels); see the separate pages for each region.

Your routine is only saved once you confirm. No account, on this device.

Work safely and follow the manual. If in doubt, or if it involves gas, combustion or working at height, leave it to a qualified professional.
