Roadmap: Connecting wood stove to existing chimney
Below is a clear step-by-step plan for correctly installing a wood stove on your existing flue.
1. Inspection of the flue
First, check whether the existing ductwork is suitable for use with a modern wood stove. Have this carried out by a certified professional. This involves looking at:
- Chimney pull
- Cracks or leaks
- Deposits or blockages
- Structural condition of the canal
2. Install chimney liner (flexible or double-walled)
In many cases, it is necessary to install a new liner in the old chimney. This provides better draft, safety and prevents condensation problems.
- Flexible stainless steel liner: Ideal for masonry chimneys with bends.
- Double-walled pipe: Often used with fireplaces or when there is no existing duct.
Make sure the diameter of the liner matches that of the stove connection (usually Ø150 mm or Ø180 mm).
3. Connecting the stove pipe to the chimney flue
Ensure an airtight connection between the stove pipe and the flue. Use heat-resistant sealant and clamps if necessary. Also ensure sufficient distance from combustible materials (read more about fire safety for wood-burning stoves).
4. Controlling air supply
Modern homes are often well insulated, so there may be insufficient air supply for combustion. Therefore, consider connecting an external air supply to the stove.
5. Testing and commissioning
After everything is connected, have the system tested by a certified installer. This will check, among other things:
- Towing capacity
- Airtightness of connections
- Carbon monoxide leaks
- Compliance with building regulations and standards
Building codes and regulations in the Netherlands
Connecting a wood-burning stove falls under the Building Regulations and must meet specific requirements regarding safety, ventilation and emissions.
- Central government - Building and remodelling rules
- NEN standards such as NEN-2757 (flue gas discharge) must be followed.
- Notification requirement in some municipalities - check beforehand!

| Chimney inspection & cleaning | €100 - €200 |
| Installation of flexible liner (10m) | €500 - €1000 |
| Connecting materials & assembly | €300 - €700 |
| Total cost of installation* | €1500 - €4000+ |
*Depending on situation, region and chosen installer.
Tips for optimal use after installation
- Ensure annual maintenance by a licensed chimney sweep (read more about chimney sweeping costs here)
- Choose dry, untreated firewood (e.g. oak or beech with max. 20% moisture content).
- Always install a carbon monoxide detector in the same room as the stove.
- Air regularly to prevent CO₂ build-up.
- Install heat shields if necessary near wooden walls or floors.
Sustainable heating: think of your environment!
When heating, think not only about comfort, but also about sustainability and health. Only use approved firewood, prevent smoke nuisance for neighbours and consciously fire according to the rules of Stookalert RIVM / Stookwijzer.nu, for example.
