Copper flue tubes

[johnthefish]

Hello, Hope someone can advise me.

I'm getting materials together for building an EMMA VICTORIA copper boiler.

The stated tube for the flue is 22mm x 1mm wall thickness.

Can't find this available from normal M.E. suppliers but have a piece of 22mm copper plumbing pipe which is exactly the wall thickness size stated.

Is there a problem using this sort of copper (ie zinc etc) or will the boiler inspector (when I find one) go mad when he sees it, stating 'everybody knows you can't use plumbing copper in a boiler' :fan:

Thanks for reading. John

7/8 x 18 swg is available from the ME suppliers so should do the job rather than risk plumbing copper. Try M-Machine if you are in the UK

Thanks again Jason. I've used m-machine before but was looking at metric sizes.never thought of imperial. Will give them a call. Thanks again.... John
