Wood burner flue liner

[shooterjim]

Looking at fitting a woodburner when we get the boiler replaced. Need a liner from stove to roof, are the twin wall flexi liners suitable for this? Seem like a cheaper option than rigid twin wall systems. Any advice appreciated.

I put one in our old cottage last year (had an open fire before) and used the heaviset grade, I think its 960? No problems

The flexible liner will need to go inside an existing chimney. If you're not burning coal then 316 grade is what you need,

Ps Mine is a multifuel and I burn coal, logs, peat etc, as per Graham if its just wood you are going to burn a lighter liner will do. I did mine in a weekend. Including hearth and all the fannying around with roofs and liners etc

Will be using the existing chimney/recess which the gas fire flue currently uses. What do you use where the flue exits the roof? Will come out of the existing hole where flue exits. does it need to be a tallish stack pipe as already there?

The easiest way to hold the liner in is with a 'hanging cowl'. The liner fixes to it and it sits on the existing pot. You'll need to fit a register plate in the flue above the stove and make sure it's airtight. Then get it signed off by the building control dept of your local LPA. I think most stove manufacturers recommend a height of 4.5 metres for the flue.

Fixed mine over the old chimney pot. Haven't got a cover on it, and given that we live in Argyll, where, occasionally it rains a wee bit, no problems. To be fair, stoves on 24/7 from sept to apr. We had the same set up when we lived in another similar property, again with no dramas!!

i picked a flexi one for nownt the other day, so you think a cowl is pointless? i hope so as spending money is a pain

[Graham]

Unless you're running the stove regularly I'd fit a cowl. In a brick chimney the masonry will absorb a fair bit of moisture. With a flexi flue any rain water will run straight down to the stove.
