2. Choosing the Right Stove
When selecting a wood burner, consider:
- Heat output: Measured in kW, suitable for room size (e.g., a 5kW stove for a 15-20m² room) Click here for our kW calculator .
- Efficiency rating: Look for an Ecodesign Ready stove, as they meet 2022 environmental standards.
- DEFRA-approved models: Required if you’re in a Smoke Control Area.
3. Placement and Clearance Requirements
- Hearth requirements:
- A non-combustible hearth extending at least 225mm in front and 150mm at the sides of the stove.
- The hearth must be 12mm thick for stoves under 100°C or 50mm thick otherwise.
- Wall clearances: Ensure sufficient gap between the stove and combustibles (manufacturer guidelines apply).
- Ventilation: If the stove is over 5kW, additional air vents may be required in the room.
4. Flue and Chimney Installation
- Flue height requirements: A minimum of 4.5 metres for effective draw.
- Chimney liner: A 316 or 904 stainless steel liner is recommended for existing chimneys.
- Twin-wall flue system: Required if no existing chimney is available.
- Distance from combustibles: At least 50mm clearance from the Twin wall Double Insulated flue to combustible materials.
- Chimney pot regulations: The flue should terminate at least 600mm above the roof ridge. (See doc J)
5. Installation Process
- Prepare the hearth – Ensure it’s properly installed and level.
- Install the stove pipe – Connect the stove to the flue or chimney liner.
- Fit the flue liner – If using a chimney, install a suitable liner with an insulation wrap.
- Seal the connections – Use heat-resistant sealants for airtight joints.
- Install a carbon monoxide (CO) detector – A legal requirement under UK regulations.
- Final inspection and test – Ensure no smoke leakage and proper draft.
6. Safety Measures
- Install a carbon monoxide detector within 1-3 meters of the stove.
- Maintain annual chimney sweeps to prevent creosote buildup.
- Use only seasoned wood (20% moisture or lower) to reduce emissions and soot.
