no, it is to do with keeping the flue hot to produce draw, thin wall SS heats up quick and should be proof against corrosion, a brick chimney takes far to long to heat up and will be a fire problem should it coat with creosote deposits, Rick

if you do not run a flu all the way up the chimny to smoke degrades the pointing and eventualy it will come in to a bedroom or loft space...

so i was told..

yh I think thats right, sure I've read that before. In the old days, they rendered the inside of the chimney as it was built....well, they certainly did ours.

yes that is the whole point, golden years past the fire was kept in all the time chimney always hot so good draw, cold chimney takes ages to attain a draw due to the smoke rising till it cools enough to start to drop, now it blocks further smoke rising, simples, modern SS twin wall flues heat very quickly as only have to heat the SS inner member, so draw will be good a short while from starup, Rick

Didnt get that trouble

No liner in our chimney, house was built in 1952.
Never had a problem with the burner drawing it does get swept every three months due to burning logs apparently that's what the regs are now so I was told by our sweep

Our house was built in 1925 and the chimney is not lined, the log burner works fine and gives good heat.
I sweep mine about once a year and burn wood 99% of the time, I do like to give the fire a good hot burn every few weeks, as stated before, this removes the tar and soot build up.

I sweep my own chimney, I bought a set of sticks and a brush years ago.....saved a fortune.

Big Col, every 3 months seems a bit of an over kill, is this on your chimney sweeps advice, if so, have you checked his ash bin before and after to see how much soot is being removed, I would be amazed if there's much coming out.

[spiderpig37]

You can always have your chimney tested by capping off the top and letting off a smoke pellet in the bottom to see if the flue holds the smoke and none escapes into the loft space or other fires if they are conected
For piece off mind a liner would do away with this

got some of these today so can test the chimney, was speaking to the neighbour and they pointed out they haven't got a chimney stack but i have, dunno how i missed that lol, looking at the brickwork from the outside the chimney looks to be in fairly new condition
