Wood and Creosote build up
If you are burning wood it should ideally have a moisture content
of no more than 20%. You should use wood that has been seasoned rather than wood than has been recently felled. Burning wet
wood will not only be a major contributing factor in the build up of Creosote within the flue but it is very unlikely to produce
any real heat as most of the energy produced is lost trying to dry the wood enough to burn.
Poorly maintained flues
can also lead to a build up of Creosote as well as tar. Creosote is a combustible deposit which builds up in the flue. It
is corrosive and can damage flue linings even in recently relined chimneys which in many cases will invalidate your warranty.
It is also responsible for a large number of chimney fires. Reported call outs by UK fire brigades to Chimney fires rose by
20% last year to 10,200.
Cheaper, greener and cleaner
With the rising cost of fuel many people are once again embracing
the solid fuel appliance as a cheaper and greener alternative. But before you open up chimneys that have lay dormant for many
years it is important that they are inspected to check the flue is sound and that there aren't any unseen blockages in
the chimney.
