middi · Sep 12, 2011

Purchase cost of 7 metre twin ,flexible, multifuel s/steel liner, including pot holder,rain cap and lower attachment flange £264 ( inc vat) . ( to be lowered into existing brick chimney void ).

All I need is a long ladder against the chimney ( + a couple of people for " stabilisers " ) and a bit of gut for me to claim the ladder. Alternatively, a scaffold tower, proper scaffolding or an helicopter with a decent pilot.
The last couple of option are a tad expensive.

As the "gut" front has also started to dwindle ( I am getting on a bit now to tackle high ladder work !!!), my subconcious instint led me to ask the appliance supplier to quote for supplying and INSTALLING the liner.

I nearly had a heart attack !!!!. to supply and install liner : £ 1850.00 + VAT.

All of a sudden I became very courageous, the " gut" came back. I am asking my son and son-in-law to hold the ladder ( better still, I may send one of them up the chimney :wink: )

What a rip off.

An alternative might be some sort of cherry-picker machine - that's what they used to get to the (very high) top of our chimney when our liners were installed.

That sounds like a good price. I've just paid £480 for 6m of 904/904 with rockwool insulation + all the other bits needed to connect it to our stove.

I'm planning to raise it up into the chimney rather than to drop it down. This isn't the recommended way but I have a big fireplace opening so it will be a gentle bend and the flue will be partially open on the outside when we fit so it getting caught won't be a problem. We also have electricity wires closeish to the house and I just don't fancy having 6m of liner wobbling around at chimney height.

I think you got a good price for the liner - mine was almost £500 for 8m of 904 double skinned, but then the complete cost of supply and fit was "only" £1120 including the liner and everything else.

I think you'll find the insulation is just as expensive if not more than the liner, that's what I found!!

MdB · Sep 12, 2011

904/904 was £36/m. Rockwool insulation was £24/m. (Chimwrap seems to be around £45/m and is thinner which I'm guessing means it isn't quite as good - don't know though)

middi · Sep 12, 2011

My dismay was with the cost of installation as opposed to the cost of various type or fully insulated liners.

It is an external chimney stack, easily accessible with a clear view from top to bottom. I thought £ 3/400 plus parts should be more than adequate to tackle the job not the £ 1500+ parts they quoted.

I did ( very diplomatically) refuse the services, also mentioned the fact that it was a bit more expensive than I was willing to pay. The salesman started to justify the price by quoting " health and safety". In his case it was more " wealth" than safety.

I need to do a similar job myself but I’ve got no idea on how to do it and what materials I need. Can anybody provide details/sketch on how it all fits together? Does the liner (which I presume is flexible) get fed down the chimney pot or dose the chimney pot have to be removed first. How is the liner fixed at its uppermost level i.e. how is it fixed to the pot? Also in my case I need to attach the chimney liner to a wood burner and I believe the first meter or so from the wood burner upwards (before it goes up into the chimney) is usually some kind of stainless steel or other solid non flexible insulated tubing. Details on how it all fits together at the burner end would also be appreciated.

Removing the chimney pot method:

You can also hang the liner from the chimney pot (which is what I'm going to do) using a chimney hanging cowl:

Vitreous enamelled stove pipe is what you want connected to your stove with an adapter to the liner.

Most of my bits turned up today unfortunately one was wrong

There will probably be lots of photos later once we have installed it.

Well that cannot be too difficult then!

Schoolmarm · Sep 13, 2011

I would prefer to hang the liner off the pot here as I can't bear the thought of the chimney coming off.

It says not suitable in exposed locations. Does anyone know why? We are extremely exposed and high up.

Flyfisher · Sep 13, 2011

We have two lined chimneys; one has the liner hung from the existing pot and the other one has the liner underneath the pot.

I can't see why a liner hung from the pot wouldn't be suitable for exposed locations. If anything, it would help to hold the pot in place! But we're not in a particluarly exposed position so I can't really offer more useful advice.

The hung liner was very quick to install (I've posted a photo here somewhere showing the chap balancing on the chimney and feeding the liner over his shoulder and down the chimney ( :shock: ) with no disturbance to the chimney structure.

The other liner was installed under the pot because the chimney was being rebuilt at the time and the scaffolding was already in place. Given the chimney was already being repaired, the liner installation was very easy. In effect, it is simply 'hung' from a plate underneath the pot.

A pot-hung liner can, with care and depending on the chimney positioning, be installed without scaffolding but I can't imagine installing the other type without scaffolding in place while the flaunching and pot was removed then replaced and re-fllaunched. That's how the installation costs build up.

MdB · Sep 13, 2011

When I went up the ladder to look at our chimney pot, I was rather surprised to discover that the chimney pot plus its flaunching had about a 1cm gap underneath it. The cement had failed to adhere to the bricks and the whole lot could be lifted up. It was rather fun to get down as it was too heavy to move with the flaunching and the two metal bars supporting the pot had shifted meaning it was only the flaunching that was stopping the pot falling down the flue...

How does it work if you don't want to use a rain cap? Flyfisher you said you hung yours from the existing pot? Is there a standard adaptor or clamp to use? My pot looks like this

middi · Sep 14, 2011

After the ( flexible) liner has been inserted into the chimney a special adapter is secured onto the liner and this rests on top of the chimney pot collar. The whole liner weight is held upright within the chimney void.

A stainless steel rain cap ( purpose made usually ordered with the liner) can then be inserted into, and above, the adaptor. This cap only protrudes about 7 or 8 inches above the chimney pot.

If there are issues with listed building CO ( highly unlikely !!) about a few inches of s/steel capping protruding above the pot, and deemed to be unsightly, then the clay pot needs to be removed and the liner holding collar has to be inserted at the base of the chimney pot. A clay rain cap, if wanted, or a chimney pot with inbuilt rain cap would be less obtrusive from a CO point view.

A rain cap is certainly advisable and there is a wide range of liner cowls available, as shown in MdB's earlier post. I'd guess your rain cap is just sitting inside your chimney pot and would be easily removeable to allow the fitting of a new liner/cowl. I don't know if there is a way of hanging a liner from your pot and still be able to use your existing rain cap but I suspect not. If you particularly want to retain the existing rain cap then I think you'll have to remove the pot before installing the liner, as Middi describes.

That looks like it's capped and will need to be replaced to get any draught.
In our last place we had an open fireplace which we wanted to use - the sweep told us we'd need to get that kind of pot replaced. The builder had fitted one of those to cap it - it allows some ventilation of the chimney but not enough to draw a fire.
I could be wrong but I'd check with a professional if I were you.

You are not wrong, that's a hood top used for venting the flue only.

Johnboy · Sep 14, 2011

Earlier this year we had a flexible flue liner and rain cap fitted to the secondary chimney in our cottage in Wales. The company we used* supplied a 'bird proof' stainless steel rain cap pre-finished in a terracotta colour. It was very easy to fit and looks fine in place.

Due to the poor condition of the internal surface of the chimney we decided to opt for a Vermiculite/limecrete lightweight 'cement' in-fill to give us some additional strength as well as insulation. So far it has worked out well...

* http://www.firesonline.co.uk. I would have no hesitation recommending these people. The telephone staff were very knowledgable and helpful and the order arrived bang on time. What more can you ask for?

CliffordPope · Sep 15, 2011

It would take more courage than I possess to stand at the top of a ladder and wrestle a long convoluted steel snake down the chimney. It's bound to catch on something, so you'll have to wriggle it about or rotate it. surely?

Can't it be fed up from the bottom? Straighten out the coils as it goes up so it doesn't jam on the sides of the chimney, then secure at the bottom with a bracket and a clamp. You could have a rope from the top going all the way through to the bottom of the liner, so someone could pull and take the weight as it goes up.
