I'm thinking of DIYing a chimney lining. (Mostly because I can't get
someone to do it until Feb) Background is that I opened up a fireplace
which had a hideous gas fire, got it swept - sweep suggested a liner
as it looked like it had had a chimney fire in the past - there already
is a register plate and it seems OK, so want to install a wood burner,
but need the liner in.

I've read a few things online & watched someone line another chimney
in the house for a range cooker (big aga-like thing) and it seems fairly
straightforward. Access to the roof will be the hardest part due to the
local topology, but ought to be managable.

Put the liner in, fill with vermiculite, seal it up, put pot back on,
connect stove and off I go?

So any gotchas, pointers, etc. ?

Cheers,

Gordon

Gordon, are you going to use the flexible stuff or a jointed sections?

Flexible. Only becaue I've never heard of jointed stuff!

I'm not sure if this is what Chris means but my chimney liner consists
of a number of 1m long steel(?) pipes of about 20cm diameter which you
slot together and then slide up the chimney. This means you can build
up from the bottom (If there's room to work) which was great for me
because a) I can't stand heights and b) my chimney is difficult to get
to from outside.

OTOH I do have a 'walk-in' fireplace so that made it easier :-)

Cheers,

John

Ah right. I see now. Unfortunately, the flue isn't vertical. Theres a
zig-zag as it goes up to get round the bedroom fireplace directly above it.

As I understand it any work on a flue requires building control approval
nowadays.

1) Do you really need a liner? It's a lot of trouble, if not needed.

2) The corrugated flexible liners are not suitable for solid fuel.

Probably.

When the chappie was in to sweep the chimney (2 weeks ago) he recommended
it. He said it looked like the chimney had had a fire in recent years
(it's been blocked with a gas fire in it for the past 7 or 8). There
were a lot of glassy tarry deposits on the walls, and when he swept it
what came back down wasn't soot, but a bucket load of crumbly mortar
and half a brick...

Other houses in the street aren't lined (that I know of), but then they
might not have suffered a chimney fire either...

2) The corrugated flexible liners are not suitable for solid fuel.

Ah, that's good to know. No-one has mentioned that to me before.

Thanks,

Gordon

Do you really need a house fire?

You do need a liner. the internal dimension should be matched to the
woodburner you use. There are different grades depending on fuel, ie
for gas, wood, coal

Might pay you to ge a new double insulated pipe scetioned thing...rather
than install a flexible.

You have to drop from the top dowm. Really needs scaffolding.

Easy unles your flue is kinky. Then you have serious problems.

I thought you only need the double skinned, double insulated stuff if it was
possible for some to touch it and accidentally burn themselves?

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.
