Re: Interesting Chimney
I've seen chiminys like this on a lot of houses. I thought it was an accepted procedure.

Re: Interesting Chimney
That is called a sloped offset chimney.
Very common years ago. One thing you have to worry about is cracking where the slope starts, cracks commonly form presenting a fire and gas hazard. |

Re: Interesting Chimney
It will reduce the draft, but I don't think that is why they did it.

Re: Interesting ChimneyQuote:
It used to be thought that a flue needed to travel at least its own width to reduce any downdraught and increase the draw. We were taught this at college as can be seen from these old drawings.   Nowadays a straight flue is said to be more efficient. How much would you charge to rebuild these 4?

Re: Interesting Chimney
Ive only ever seen an offset chimney built in to a gable wall end, seen lots of twisted chimneys, great to look at but a bugger to re-point!
Cheers Dave |

Re: Interesting Chimney
On a recent job, the chimney in the first photo was going to get repointed till we took the slates off the lower roof to discover they had taken the chimney breast (flue) out below it and it was being held up by a timber batten!!(photo 2)
Cheers Dave P.S. we took it down....carefully! |

Re: Interesting Chimney
Taking the chimney breast out and leaving the stack suspended is quite common in the UK. It was done a lot in the 70's when everyone wanted central heating and open fires went out of fashion. It's OK if the stack if supported with gallows brackets in the roof space, but many aren't sometimes with deadly consequences. Here is another typical example.

Re: Interesting Chimney
Ive seen plenty of offset chimneys like in the opening post. Usually they are laid up against a pair of 2X4's to prevent them from falling over while the mortar is still wet. The 2X4's are usually left in place.

Re: Interesting Chimney
The chimney in our house starting in the basement is on top of a massive arch system. It has two flues from there that are on either side of the staircase, then merge above the stairs to come out the top in only one spot.

Re: Interesting Chimney
Interesting Thread...
Is the verdict in as to why this was done? I have seen this in several historic homes we have renovated. Always figured it was to have the chimney offset from the ridge (specially because the offset occurred only in the attic)... But, after seeing a couple homes where the chimney runs straight thru the ridge, I am wondering if there may be some other reason... Thanks, Bonz |

Re: Interesting Chimney
I came across these chimneys on a job in Liverpool, thought they looked rather nice!
I think a chimney can come through a roof where ever but the pots need to be about a metre above the ridge line to stop down draft! Cheers Dave |
