Solid Fuel Stove Downdraught in windy weather

arctictree · 09-12-2011 05:16PM #1

I wonder if someone can give me some advise here.

We have a solid fuel stove which works fine in calm weather but when its windy the fire can be blown out or smoke comes into the room when we open the door. Obviously we really need to use the stove when its cold and windy!

Part of our problem seems to be that the flue is a bit short on the outside wall as its the back wall of an extension and only 8 feet high. The flue goes up about
another 4 feet but its still below the ridge of the house.

Had a look on the web and maybe some sort of a cowl could solve this but I also see that this does not work in all cases.

Also, anyone know anyone in Wicklow who could come out and sort this for us?!

Thanks

Ideally the flue should be higher. Most stoves need a 4m chimney or some need even higher.

I would add some more twin wall flue or use a H cowel. These are brilliant for downdraught problems, but ugly.

Thanks for your response. Just wondering which one to order. Is the 200mm the diameter of the outside flue? Do you think I could just fix this on myself?

If it's a twin wall flue it would be the inside diameter of the pipe it would have to slot into. So if 150mm internal then thats the size you need etc.

I would give them a ring and ask them if it will fit your make of flue. I'm sure it will as they mention fitting to twin wall fabricated chimneys.

They say to fit it by using some self tapping screws.

Also living in wicklow and have a similar problem when its cold. Have adequate length of external run flue and a H cowl. Did a bit experimentation and i find if i open the inspection elbow and heat the inside of the flue prior to setting the fire then I don't have a problem. Less than top notch flue methinks.
