Flue for stove

doniepony

Hey everyone

Builder made bit of error in my new build as he assumed that I was putting an open fireplace in my new build when in fact I am putting a stove in (as was very clear in spec). I have heard that a straight flue is better for a stove but this is not possible now as he was allowing for a bend in the flue (for open fireplace) and if I was to put a straight flue in it would be mean a very high chimney stack. I know I can use flexi flue but just wondering does this affect the effieciency of the stove (draughting etc) or is there another system that can be adopted to make it work better.

Thanks in advance for any feedback

Surely he read the spec before building! Is there an air supply for the stove??

Can you use an inset stove. I think they look better anyway. My parents have had one retrofitted to an existing open fireplace - working great

Can you please explain the text in bold?
I am confused.
Either flue was going to end up say at ridge level or 60cm abpve so the bendy flue will in fact be a bit longer

id leave the flue as it. i cannot see any real justifiable reason to go to the cost of changing it at this stage.

Ok thanks, just wondering if anyone has had a problems with having a bend in their flue for a stove so-thats what i'm worried about really-whether draughting could occur or smoke would be more inclined to come back into the stove with a bend-was talking to a fitter today and he said that the straight flue always works better.

Cheers again

Speak to the technical dept. of the stove manufacturer that you have chosen. I'd be less inclined to trust the opinion of a fitter. For years the man down the pub recommended straight flues for an open fire, then one with a bend, then straight again.

I have a bend in my flue! I cleared it with th manufacturer who said it shouldn't be an issue. I won't be using the stove for another 4 months though so can't tell you if it does work.

I also have a bend in my flue as builder said this is the best design for a proper draw! I installed a stove 3 weeks ago and it works fine. In fact if anything the draw is excessive. I have it installed in a west facing external wall with an external air suppy duct going straight out through the wall at the rear. This provides a plentiful supply of air to the stove so much so that I shut down the air supply to stove by about 50% in order that I can light it - otherwise the excessive draft would knock out the fire. However, my problem is that the external air kit is not sealed properly to stove and it leaking cold air into the room. During the windy weather of the past couple of weeks this was significantly cooling the room. I've got the installer to come out again to resolve the problem. He assures me it is resolveable but Im a bit concerned that this may not be fully possible. Its seems a pity to have a fairly airtight house and then come along and spend €2k putting a hole in the external wall!!
