April 2014 Blog
I would like to start this blog by going back over what I have reiterated in some previous blog’s and this concerns Wood/Multi fuel Stoves that have flexible stainless liners running from the top of the stove pipe up through the flue and terminating via either a suspending cowl or rain cap terminals at the top of the chimney pot.
Many, many people who have had this system installed over the last few years are, for some reason, under the impression that they do not need to have them swept on a regular basis! It is with this in mind that I have, with the kind permission of Wood Burning Solutions, one of Kent and Suffolk’s Premier Stove Suppliers and Installers, added a photograph which they recently took at a property in Suffolk.
This photograph shows the top end of a flexible stainless liner with the terminal removed. As you can clearly see there is a huge amount of tar build up inside the liner. The build-up of this Tar has been, in most part, caused by
1: The burning of Wet/Unseasoned wood that far exceeds the recommended 20% or below moisture guidelines advised by all reputable Stove Manufacturers, Chimney Sweeps and HETAS.
2: Not having the Appliance Swept.
Once/Twice during the Burning Season depending on usage is advised.
Had this Stove and its Liner been swept regularly any problems regarding tar build inside the Liner would have been quickly noticed by a Qualified/ Certified Chimney Sweep and the owner could have been made aware that something was wrong in the operation of the appliance. This is not something I come up against
If you have access to them, Kiln Dried Logs are excellent. Although slightly more expensive than normal logs these logs have a moisture content which is usually between 8-15% which is ideal for your Stove. I personally always keep a Cube/Pallet of Kiln Dried Logs to supplement my main stock of Dry Seasoned Logs. My Seasoned Logs, which I manage by a rotation system, have stood for at least three years. Below is how I personally do it.
Year one: Logs are cut and split to the requirements I need for my particular Stove and are stored outside, open to the elements, during the Spring / Summer and Autumn months of the first year and then covered during that winter.
Year two: Logs are brought in and stored under Cover.
Year three: Logs are moved into my log store close to my house ready for the burning season.
Logs can be burnt using a much shorter Seasoning/Drying Cycle but having been brought up on a Farm on the North East Essex Coast, where the AGA and an array of Wood Stoves were common place, it was drummed into us from a young age by the “Old Folk” that this was the way to do it and that is how I have done it for the last 50 odd years.
Until the next time
