temporary flue fix for combi condenser boiler

sb1456 · 11 Feb 2011

My house is currently being extended, and the boiler flue that was on an external wall is now technically on the new internal wall, although there are no windows or roof on the extension at present so it still vents fine. However the extension roof goes on to today and I need to temporarily vent the boiler to one of the yet to be glazed window openings about 2m away.

Basically is it ok to temporarily extend the flue, with use of flexible aluminium ducting or even a length of soil pipe. This will be a temporary fix of no more than a week, which by when the new extension is fully water tight and glazed, the boiler will then be moved to it's new location in the extension.

The boiler is an Ideal Isar 30he combi condenser.

Thanks

Absolutely not permitted using that method.You can extend using correct flue kit though.

And just to rub salt into the wound, I'd take advantage of the building work to chuck the Ideal in the builders skip and get a boiler that would be reasonably reliable.... They are not well known for their reliabillity..

OK, i'm glad to be giving everyone a giggle, and slightly amused that some people have taken offence. But basically the consensus seems to be no boiler for a week or pay someone £200 to extend the flue for a 5 day fix. Then move the boiler again.

Just to make people clear, The extension is not inhabited, and the windows and doors have yet to be put in, neither has it been knocked through., so essentially it is totally open to the elements, except for a felt and battened roof (not tiled yet).

So just to satisfy my curiosity could someone please explain what would happen if I put a 2m length of aluminium flexible ducting on the end of the flue and fed it towards an unglazed window in the uninhabited and open to air extension.

Thanks again

What could happen is the flue could rot or more likely a bad joint could disperse poc back into the property.not to mention the effect the flue run could have,if your lucky it may just wreck your boiler. I do hope you don't have children or this is another wind up.I'd be having a serious word with the builder for even contemplating laying 1 single brick, but he's probably a mate from the pub

Advice like that goes against all regulations and please accept that no one will
OK your proposal.Your boiler is ok at the moment but as soon as you enclose your extension it should not be used unless flued correctly.I'm not giggling by the way as I consider this a serious matter.Cheers.

Just to make it clear, the answer is: no, you can not do it. Pay up, or sit in the cold.

Thank you for the reply 45yearsgasman, the only person who was both polite, and who actually bothered to answer the question fully.

All the rest of you need to brush up on your social skills.

Finally my builder did not suggest the temporary fix. It was my cunning plan, and as I wasn't sure if it was safe, so I decided to ask on the forum. Now that I know that it isn't, and why so, I won't do it.

Thanks

I am sorry if you've found some replies rude. However the only publicity this trade gets is when someone is injured or dies as a result of shoddy gas work. What you suggest is like asking if it's ok to drive after 15 pints of lager if it's not far and there's no-one about on the road?'

trouble is, a flue takes in clean air as well as exhausting combustion gasses.

with what you are suggesting, the boiler will have no choice but to breathe in its own exhaust gasses...this wont do it much good..!!

Why not get your builder to arrange for the plumber/heating eng to be there the same day and fit it into it's final position.
