V8landy Posted June 26, 2011 Report Share Posted June 26, 2011 Hi Been doing a bit of research into flue lines, as will be getting scaffolding up to chimney to do some repoiting etc, and so will combine to 2 jobs. Had 2 prices in to do the lining only of about £1500, which not bad I thought, but I can get all the bits for about £300, scaffolding is costing £400, + I get to repoint the chimney which I had another quote of about £1000. Anyway, I have looked on a few sites like http://www.fluefactory.com/index.php?function=DISP&CID=5 http://www.flexifluedirect.com/product_info.php?cPath=22_32&products_id=400 And all very similar prices. Some good offers for 316/904. Given the 316 is outside it does not come into contact with the gasses, only need the 904 on the inside wall. All 1.2 mm thick and fully approved. Other question is about fitting to my stove. (see pic below, false hood removed which covers the metal pipe and top of stove) The current metal pipe is about 7" so I dont think I will get a 7" flexi down as their outside diameter is greater than 7". So I will have to use 6" and put an enlarger to the top of the stove. I was planning to remove only the 45 bend and feed down the chimney stack and enter the section of 7" pipe through the stone cladding and then connect to the top of the stove via an enlarger. Does that look OK? Quote Link to comment Share on other sites More sharing options...
Ricko Posted June 26, 2011 Report Share Posted June 26, 2011 I sent my woodburner straight up an existing chimney after smoke testing it. A flue would perhaps only be needed if a chimney was known to leak smoke. Cheers Quote Link to comment Share on other sites More sharing options...
V8landy Posted June 26, 2011 Author Report Share Posted June 26, 2011 (edited) Maybe I am been over cautious then??? Chimney is ordinal 1948, so possibly built well? Designed as an open fire. Chimney sweep guy says it is in good condition. No evidence of smoke leak. It was more piece of mind, and I will be up there repointing and scaffolding. Dont want to be up there and then needing to get scaffolding out again next year to do a liner. 25 year gauranteee is good for me.

twitchynik Posted June 26, 2011 Report Share Posted June 26, 2011 My woodburner is only flue'd to the register plate. Chimney is over 150 years old. Built things properly in them days. Quote Link to comment Share on other sites More sharing options...
rimfire4969 Posted June 26, 2011 Report Share Posted June 26, 2011 I don't know much about chimney linings. I had a woodburner put in last year. I already had scaffolding up to sort a roof problem, a friend of a friend works for a stove supply and install company. He fitted the stove dropped a 6" liner down the chiney put a cowling on top and connected it all up, tested and certificated for £650.00. I was told lining can cost around £15.00 and upto £35.00 per metre. Quote Link to comment Share on other sites More sharing options...

Dont you mean going from 6" up to 7" ? Just use an enlarger piece. Edited June 26, 2011 by Fisherman Mike Quote Link to comment Share on other sites More sharing options...
Fisherman Mike Posted June 26, 2011 Report Share Posted June 26, 2011 I would also advise you to keep that stack of wood at least 300mm away from the body of the stove...or hide the picture from your insurance company Quote Link to comment Share on other sites More sharing options...

But we generally dont store it that close, it just there as we are decorating just outside the picture so moved in a bit closer to the stove.

Ricko Posted June 26, 2011 Report Share Posted June 26, 2011 Also whether you use a liner or not, avoid wood with paint on it or wood that has been creosoted. It will casuse tar deposits in the liner/chimney. Quote Link to comment Share on other sites More sharing options...
Vince Green Posted June 26, 2011 Report Share Posted June 26, 2011 Also whether you use a liner or not, avoid wood with paint on it or wood that has been creosoted. It will casuse tar deposits in the liner/chimney. The truth is that any resinous wood also leaves deposits in the flue as well and thats just a fact of life when you burn wood, part of the logic to having a flue liner is that the smoke goes up the narrow flue faster and takes more of the deposits with it. Its a good idea to have a coal fire in the stove from time to time to (if its suitable) to try and stop the resin buiding up too much.

V8landy Posted June 26, 2011 Author Report Share Posted June 26, 2011 And get it swept regularly . I am thinking given the time frame the stove has been in and it was built in a good construction time period, and finally that we only use it for realy cold times and e.g chritmass day, it is not wroth the time or money to fit a liner.

DSPUK Posted June 26, 2011 Report Share Posted June 26, 2011 I would say while you have scaffold and are up on roof then do it - for what it costs it's worth it for peace of mind - I would say your stove is an old one by look of it and if you upgrade at any time then you will be grateful for lining flue - if you do line it don't forget it infill with vermiculite at same time. dave Quote Link to comment Share on other sites More sharing options...

But at least you think the same way I do. Yes it might have lasted 30 years, but if could go next year, and that would be more scaffold cost, and possibly when I am not in the mood to do it. S*d it I am going with a 316/904 liner...£300. As for the vermiculite, the liner companies say not needed if only a small void between liner and chimney and also when chimney is in middle of house.

al4x Posted June 26, 2011 Report Share Posted June 26, 2011 My woodburner is only flue'd to the register plate. Chimney is over 150 years old. Built things properly in them days. not so, you actually may be fine if you burn very well seasoned wood but your chimney won't have a clay liner in so deposits soak into the bricks and mortar till eventually you have a fire. I'd always fit a liner unless there is a clay liner fitted when the chimney was built. Vermiculite is used so it draws better you can avoid it but the chimney takes longer to warm up and draw well. I've fitted a few liners now and its so easy and done properly you don't need to sweep them any where near as regularly the fire works better and you know you shouldn't have a serious chimney fire Quote Link to comment Share on other sites More sharing options...
V8landy Posted June 26, 2011 Author Report Share Posted June 26, 2011 Other thing with muiti type stoves is they are that efficient at giving off the heat into the room, the chimney is cooler than a normal fire, so deposits build up and dont really get burnt off like an old open fire would do.

bicykillgaz Posted June 26, 2011 Report Share Posted June 26, 2011 see if you've got a plumbcenter local i use to work for one of there sister companies and i know they sell them, might not have them in stock but should be fairly quick delivery and should be able to answer any questions about what you will or won't need. gary Quote Link to comment Share on other sites More sharing options...

As the man says, fit a liner. It will work better and be more easily maintained. Quote Link to comment Share on other sites More sharing options...
