What's the difference between woodburning and multifuel stoves?

First up multi-fuel stoves, they are designed to burn a range of solid fuels:

  • Wood logs
  • Smokeless fuels
  • Anthracite
  • Peat/turf briquettes
  • This is made possible by the inclusion of a central riddling grate and ashpan or a raised grate that has moving bars which allows the multi-fuel stove to efficiently burn a variety of fuels.

    Solid fuels excluding (wood) burn best from the bottom up this requires the air intakes adjusted accordingly. this enebales efficient combustion as it introduces air from underneath the grate.

    After every burn, the fuel bed needs to be de-ashed to create optimum combustion and efficient burning. The design of the multi-fuel stove therefore usually includes an ashpan underneath the grate to both collect and enable removal of the ashes.

    Next wood burning stoves, designed to only burn wood:

  • Firewood – hard and soft wood Kiln dried or naturally seasoned (20% moisture content or less).
  • Heat logs
  • wood burning stove ar more effective when the fuel is allowed to sit on a bed of ashes. For this reason wood burning stoves usually have a flat base. This ensures that the ashes created when logs are burning are collected in the base of the stove to allow logs to be placed on top: this greatly assists the combustion process. Wood burns best from the top down.

    Wood is considered the most important single source of renewable energy. Using wood for heating reduces carbon emissions by 90-95 per cent compared to fossil fuel use.

    I don’t have a chimney – can I still have a wood burning stove.

    Yes! Although having no chimney will require an insulated twinwall stainless steel chimney this is the simplest, most cost-efficient flue solution. A twinwall chimney is made from rigid stainless steel fluepipe manufactured with insulation sandwiched between an inner and outer steel skin.

    Modular components of varying lengths and including bends, supports, flashings and inspection chambers, are assembled to provide a fully-integrated flue between your wood burning stove and a safe terminus above roof height. A twinwall system can be installed either internally, rising up through the building and out of the roof, or it can pass through the external wall and up the outside of the building. The height of the chimney will depend on its position relative to the roof and other parts of the building.

    What is DEFRA Approved, smoke exempt, SIA Ecodesign stoves?

    DEFRA approved stove. “DEFRA exempt stoves” or SE (smoke exempt) are all the same just (different terminology) these stoves are cleared to burn specified fuels (usually wood) in smoke control areas, these fuels are usually disallowed”.

    More information about fuel types DEFRA An approved stove can be used in a smoke control areas to burn wood. Non DEFRA stoves cannot burn wood in these areas.

    SIA Ecodesign Ready stoves are designed to reduce PM emissions by burning wood more efficiently and completely. SIA Ecodesign stoves have been independently tested by an approved test laboratory and met the emissions and minimum efficiency criteria for Ecodesign.

    In summary, Ecodesign is the European-wide programme to lower emissions. It is due to come into force for stoves in the UK in 2022. SIA Ecodesign Ready stoves will meet the Ecodesign requirements and are available now. consumers should choose a Defra exempt stove which is also Ecodesign Ready.

    How much will it cost to install a wood burning stove?

    Generally there's not a set price for stove installation, Every customer has their own specifications and requirements. And a site survey from a HETAS engineer is always required

    We always recommened stoves from quality UK and Scandinavian manufacturers. Prices range from £500 for a small stove up to thousands. A good quality stove around the 5kw range is about £1000 If your looking at a wood or multifuel burner for the first time and your preference is traditional or contemporary, there is a product to cater for all tastes & styles on the market.

    Things to consider additional costs.

  • Have a chimney already.
  • Fireplace opened up insides rendered, tiled etc.
  • Need gas appliance removed capped.
  • Install new hearth where existing is insufficient.
  • Oak beam
  • Firesurrounds
  • Installations into a exixting chimney start from £1,000, which includes lining the chimney, commissioning including HETAS registration.

    Installations without a chimney breast requiring a twin wall insulated chimney system start at around £1,900.

    As a guide an average instalation including a stove, Fireplace opened up new hearth would be around the £2,500 to £3000

    If you require building works there will be additional costs.
