Chimney Lining...

[Christian McArdle]

Where do you get your liquid wood from? My supplier closed down.

OK I phrased that wrongly as I thought there was only one, double skinned, flexible liner suitable for wood stoves on the market. The type I am familiar with arrives as a coil and the instructions are to fit it as one, un jointed, piece.

You were right, this type is not suitable for wood stoves, I was pointing out that I was aware of one flexible system that could be used, subject to caveats.

As far as I know the purpose of it is two fold - to make sure the outer surface never gets hot enough to cause a fire when going through flammable structure, and to ensure the inner surface IS hot enough not to get soot condensing on it.

But I may be wrong.

[The Natural Philosopher]

Right. I know what you are talking about and vice versa.

Now what was teh original question?

I think the short answer is get expert advice here from BCO.

I have to say thatwhilst some building regualtions are inherently stupid and politoically inspired the ones relating to fire safety are honed down over years of interaction with those who investigate domestic fires, and frankly , I'd stick to them.

Had a fire in the next village. Thatch went up due tto pointing failure in wood fired chimney flue. Had a liner, but it only went a few feet up.

House very badly damaged.

Your choice.

Old chimenys leak and fail and are bloody dangerous when used with high temperature flues - and a roaring solid fuel fire is way hotter than oil or gas burners - lots of combustibles can get up there still combusting - I would pay teh money and do it properly, or not at all.

This site seems to indicate that flexibles are suitable for all fuel types

locking jointing system and the smooth inner with the corrugated outer for protection during installation. The first is the reason it has to be inserted the right way up and why intermediate joints are a problem, the second is to stop a tar build up in the crevices which cannot be brushed out. As someone else has pointed out liners for wood fires are designed to accommodate higher temperatures, which may come from tarry deposits burning in the chimney.

There are separate rules about passing the metal chimney close to flammable objects, I believe it is actually OK to have a single skinned, like the vitreous enamel ones, metal flue passing in the room.

Yes it's mainly to keep the flue gases hot and above the dewpoint of any vapours and to maintain a good draught.
