Don’t panic – this isn’t another fitness blog reminding you that you need to get moving for your health! But it is pretty serious I’m afraid. It’s all about ‘slumbering’ your wood burner…
Wood burners (and multi-fuel stoves) are a wonderful addition to any home and can offer a great alternative to using the central heating all the time. In general, people who have had them installed recently and had contact with the installer are advised about the use. Unfortunately many of us have moved into a home where there is a wood burner – indeed this may have been a key selling point – and maybe there are no instructions for best, and or safe, use.
Here’s the technical bit: Burning incorrect wood or burning wood incorrectly can produce creosote (commonly referred to as tar). If you burn poorly seasoned wood (with a high moisture content) or ‘soft’ wood – pine/leylandii, etc. which is very ‘sappy’, this will result in the production of ‘tar’.
If you ‘slumber’ your woodburner – burn it very slowly during the day or try to leave it in overnight this will also result in the production of ‘tar’.
You might be asking yourself what the problem is with a tarred up flue – there are two main issues: the tar is very difficult to remove and is flammable. It builds up over time, increasing the risk of a chimney fire. In addition, the flue itself will decrease in size as more tar builds…this in turn will slow the draw of the flue and will result in more tar being deposited. This may also mean that carbon monoxide will be less able to escape and it is possible that carbon monoxide poisoning might occur.
To avoid this, in general terms, burn well-seasoned hardwood logs at the correct temperature (between 300 to 600 F – or 150 to 300 C). A stove thermometer will help and ‘tarring’ should be avoided.
Of course – it is also really important to have your chimney swept. And we recommend that you have this done as you stop using it – not as the winter begins. Your sweep will have more time to sort any problems and you’ll be ready for any cold nights. The fire service recommend sweep EVERY 3 MONTHS when in use…and we recommend three items that will help you: a stove thermometer, carbon monoxide alarm and HotSpot – a product designed to help.
We’ve written before about the best wood to burn so you can check here: BEST WOOD TO BURN?
Here’s to safety that makes sense.
We look forward to your call to book in a sweep…
Always buy the best you can, or ensure that you ‘season (the drying process) the wood. HAPPY (and safe) BURNING SEASON!
There’s a great little poem to guide you:
Beech wood fires are bright and clear
If the logs are kept a year.
Chestnut’s only good, they say,
If for long it’s laid away.
Birch and fir logs burn too fast,
Blaze up bright and do not last.
It is by the Irish said,
Hawthorn bakes the sweetest bread.
Elm wood burns like a churchyard mould,
E’en the very flames are cold.
Poplar gives a bitter smoke,
Fills your eyes and makes you choke.
Apple wood will scent your room
With an incense like perfume.
Oak and maple, if dry and old,
Keep away the winter cold.
But Ash wood wet or Ash wood dry,
A king shall warm his slippers by.
Note: birch bark is extremely flammable even when wet; it makes an excellent fire starter if you have lots lying around.
