do you mean the soot door to a chimney to enable sweeping above a register plate?

This not, of course, advisable if your chimney is filled with vermiculite!

 

[oldfella]

using vermiculite is fine as an insulation but a real pain when time comes to provide a bit of maintenance to the flu liner or baffle plate above the stove. I've known a lounge to be covered in vermiculate when somebody removed the baffle plate unknowingly releasing a flood of the stuff. Myself I prefer to use the wadding wrap.

Never ever use corregated flu liner for use with a solid fuel stove. They are not designed for such use and will quickly deteriate. Stove might perform well for a short period of time but don't let this fool you into a false sense of security.

Is corrugated the same as flexible? If it is, and therefore shouldn't be used, how can you get a straight flu liner fitted into a chimney that isn't straight?

 

[Nemesis]

I think that there are grades of this - some is only suitable for gas, some is more robust and suitable for solid fuel, although it won't last forever.

Filling up around it in a narrow space with something like wadding isn't simple either! You can only reach so far.

Are there any good sites where I can read up on chimneys?

I need to get a linear fitted to one chimney and want to know the options. The other chimney currently has a linear and is used as a gas fire flu. I doubt it would be suitable for an open fire but would like to know how I can check this.

Here's a start:

I'd be very cautious about the cast in situ liners, which in a period building is not good as not reversible.

We had a couple of threads recently also which might be worth reading.
Loads in the past which may be archived.

Flexible and corrugated liners are two differing terms for the same product, a 'flexible liner is designed for use with a gas fire only. When you purchase your 'rigid' liner you will find a variety of section lengths and angled lengths are available to cater for fitting into a difficult chimney flu. Of course the idea is to aim for as straight a run of flu liner as possible and above all a 90 degree bend is a no no. Its unlikely that a flu will be so extreme as to prohibit the fitting of a modern liner.

 

[Nemesis]

You can buy some pretty heavy duty ones - I think in some situations these will be about all that can be fitted. They may not last forever but can at least be replaced when required.

Getting inside a flue to fit a sectional liner together, especially in a narrow one running inside a wall, with a bend, I can't think can be very simple!

I believe burning peat/turf produces a lot of liquid residues, so it may be down to the type of fuel - doesnt seem there are any other "turf burners" on the list to share their experience.

 

[Nemesis]

The whole issue of burning peat does raise conservation issues.

While I appreciate that it has been used for many hundreds of years by those entitled to cut it (not just in Ireland either) that use was tiny compared with what is happening now with use for garden compost.

Worryingly, this website seems to be suggesting that it should have wider use. I have read the stuff about conservation, but I think it adspeak - what is being conserved isn't the natural habitat, and like open cast mining, what is put in place after isn't what went before, and which has taken many thousands of years to develop.

Unlike wood, which can be replanted, peat takes s spot longer to regenerate...

Another complex conservation issue!

Thanks Oldfella (apologies for sounding so familiar :wink: ),
I suspect the chimneys I have in mind are not too twisty, so I should be OK with a straight liner.

I guess flexible liners are easier to install in one piece as they can be 'fed down' the chimney rather than having to lower a straight liner in one piece or assembling it bit-by-bit - mind you, chimney sweeps manage to assemble their brush poles this way so perhaps it's not such a big deal.

 

[Nemesis]

Poles are very thin and flexible - used to be bamboo, now glass fibre - liner sections aren't.

In some situations it would be very difficult to use solid sectional and get it round hidden bends etc. Fine if the chimney is wide and straight. Many aren't.

For a straightish chimney, sectional ceramic are worth investigating.

Forgot to put this link in a post above:

I repeat though - the pumped liners I'd be very wary of using.

NONSENSE. there are just differing grades thats all; lightweight for gas and heavier for solid fuel.............

 

[Penners]

Just imagine how tool-pushers on a drilling rig feel! A string miles long, made up of screwed-together sections.

ireland has just built / are building 2 new peat fired powerstations.

 

[Nemesis]

Hmmmm.

Many years ago I did some consultancy work for BP regarding computerised archiving of their extensive photographic library (this was early 80's, so well before digital cameras and jpeg algorithms). One of their people showed me a photo of a well blowout in which you could see the miles of pipe that had been blown out of the well and into the sky. After rising a few hundred feet into the air, the drilling pipe started to coil up on itself and it looked a bit like a loose ball of string floating in the air.

Understandably, the photo was taken some distance from the rig and the picture itself wasn't particularly spectacular, until you realised what you were actually looking at and the enormous forces involved.

Anyway, sorry for the slight digression, normal service can now be resumed . . . .

I stand corrected , but if ten years use is all you require from a flu liner than fine, personally I prefer the solid section double skinned which offer far in excess of this (at a price).

 

[Nemesis]

How do you get it up narrow and bendy flues, with all joints secure?

 

[Penners]

Keep your back straight, and if it's too heavy for you, get someone to help you. :lol:
