SIA Woodburning Stoves Supplier and Installers in Somerset
Burning wood produces particulate matter (PM) but the amount produced depends on how the wood is burnt. Independent research conducted by Kiwa Gastec on behalf of the SIA has shown that SIA Ecodesign Ready stoves can reduce particulate emissions by 90% compared to an open fire and 80% compared to an old stove.
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. The PM emissions limit for Ecodesign is 55% lower than for Defra exempt stoves.
Ecodesign Ready stoves are also very efficient; 4% more efficient than required under current regulations. The chart above illustrates the improvement in efficiency compared to a stove manufactured 10 years ago, typically 65%, and an open fire with an efficiency of 30%.
To qualify for the SIA Ecodesign label a stove must have been independently tested by an approved test lab and met the emissions and minimum efficiency criteria for Ecodesign. The test results must be verified by HETAS. The stove will then be listed on the HETAS web site. As it is an SIA sponsored label, it can only
be applied to SIA member stoves.
Often we find customer fireplaces are too small for a typical sized woodburning stove. Therefore, the fireplace generally requires enlarging to provide the 150mm clearance required around the sides and back of most woodburning stoves. (this can be reduced depending on model of stove) Make sure your woodburner is at least 300mm from any combustible materials, such as a wood fireplace surround or mantel.
A majority of customers want their woodburner close to the back of the fireplace recess. The minimum distance is normally 150mm although this can be reduced on some stoves, please refer to manufacture specifications for minimum distances.
Wood mantels need to have a minimum distance away from vitreous pipe, this is 3 x the diameter of the vitreous pipe. You can reduce this distance by installing a heat shield to back of the wooden mantel. This will reduce the distance to 1.5 x diameter of vitreous pipe.
Always ask a professional builder to enlarge your fireplace and ensure a supportive lintel is in place.
Always make sure you use a non combustible hearth of at least 12mm thick.
Please see diagram as a guide.

Which fuel should I use for my wood burner?
Burning wood has a significant less environmental impact compared to fossil fuels and burning wood releases the same amount of CO2 then it would produced if the log was left to naturally decompose in the woods. Wood can also be transported easier and requires less processing and there are huge resources of wood in the UK, thanks to properly managed woodlands.
Many customers think they need a multi-fuel stove, although most only ever burn wood.
Why is log moisture content & wood density so important?
There are 2 elements which you need to consider when purchasing fuel for your wood burning stove, both will make a significant affect on the calorific value (CV) of your fuel.
- Moisture content
- Wood density
Wood with a moisture content of more than 25% could result in poor combustion and result in an performing stove together with creosote build-up in your chimney. We provide a moisture meter with every new stove installation so you can check your suppliers log moisture content before purchasing.
You may have a choice of hard wood or soft wood logs. Hardwood logs are generally more dense and burn longer and generally are a more popular choice.
What are Seasoned logs?
You will hear the term ‘seasoned’ often when purchasing logs. Logs can contain 50% water when initially cut so need drying before burning or ‘seasoning’ to reduce the moister content to 15%-20%. Some woods need many seasons to fully dry, so use your moisture meter to check water content before you purchase.
You may have you heart set on a particular style of stove, but we recommend you clarify with your stove supplier and a Hetas installer that the stove is suitable for your environment.
Rule 1: Always ask a Hetas Installer to view your fireplace before purchasing a stove, so they can advise on the following:
- Room ventilation – It’s vital to provide stove with enough air
- Hearth size, thickness and material type
- Power of stove required in Kw
- Location of combustible materials
- Flue type required
Wood Burning Stove Power Output
Installing a wood burning stove that generates too much heat or too little can be an expensive mistake and we have replaced many wood burning stoves installed by other unregistered Hetas installers, as they are commonly too powerful and can’t be used without opening windows, which may affect airflow to the stove.
It is essential to select a stove that has a power output and good heat control ability which best suit your requirements. There are a number of factors to consider below to assist with choosing a stove with the correct power output for your property. A comfortable room temperature for most people is 21°C in a living room and 18°C in hallways, kitchens, bedrooms etc. These temperatures should be achievable from your stove without excessive fuel consumption.
Stove Purchasing Considerations
- The age of the property – Older properties are generally less insulated
- The cubic volume of the room – Calculated by Length x Width x Height
- The number of doors and windows, are they kept open?
- Is there stairs in the room allowing heat to escape?
- Is there additional ventilation or do you like to keep a window open?
- Personal heat preferences. Elderly people may prefer a warmer temperature
- Exposed locations. Is your property exposed to elements? i.e Exmoor or Quantock Hills?
- How often do you have to refuel the stove and location of fuel storage?
Many stoves have to be fueled every 45mins, although some stoves have a much longer refueling time.
- Never buy a stove without a CE mark as it’s illegal to install in England.
Wood Burner Stove Fuels
Fuel choice is an important consideration, including budgets, age and storage etc. Most wood burners have about a 75% wood burning efficiency and is more sustainable then coal. Coal generates more CO2 than wood, although smokeless coals produce less particles and can be very convenient for longer burns.
