Budget Chimney/Flue

[persianharry]

Hi everyone, I'm new to the forum and live in sunny Adelaide, South Australia.

I'm trying to build a budget DIY oven but struggling a bit with a budget option for the chimney. I don't want to just put galvanised pipe on it as it won't last, so has anyone got any ideas where I could get some stainless steel tube that doesn't cost the earth, or offer an alternative material?

Thanks

You don’t say what size your oven is, but for ovens in the 650-1000 mm diam you need a 150 mm (6”) pipe or cross sectional area equivalent for a square or rectangular chimney. A clay drainage pipe could be a good and cheap solution for you but you would have to insulate it or it will crack. A steel boiler pipe is another alternative. Being much thicker than a galvanised pipe, rust issues are reduced..

Thanks very much David, I'll visit my local plumbing and heating suppliers tomorrow and see what boiler pipe I can get hold of, seems like the way to go.

I'm in the same boat so please keep posted on what you find.
