Extractor up chimney?

[illmonkey]

In our terraced house, the only place in the kitchen for an oven is in the old fireplace, therefore, the only place for the extractor is above it, in the chimney.

I was just going to fix it in, and let the hot air escape up the chimney with no flue or anything, but turns out that might not be the best idea.

As we're terraced, I can't go out from the back of the fireplace, the only option to re-route it would be out the back of the kitchen, but it's a good 3+ meters.

Is there a way to allow the extracted air to go up the chimney space?

Why is it a bad idea? I've installed many in an old chimney. Unless the chimney 'leaks' smells/smoke I can't we an issue
Pref obviously it needs to draw

I've read if you use a flue it causes condensation, if you don't it can cause fires!

I doubt we will use the extractor, it's more for lights.

I think its in the unlikely event of grease and crap getting up there and one night you leave the pan of chips on whilst you go and take a dump and PHOOOF- chimney fire!

A non working chimney needs to be adaquatly ventilated anyway.

In reference to grease etc, just look at a fireplace of old and see where the old range was built within, or even older where they used to have a spit in it to roast meats etc . I can't see where an extractor would caused more problems than those.

Shouldn't the filter in the extractor remove most of the grease anyway ?

So short answer is, no problem. There is no chimney cover, I'll probably fit one to stop water, I was also considering a flap on the top of the outlet to stop dirt getting in.

No need ref dirt and extractor, they have a self closing flap anyway. Good shout putting a cowl etc on the chimney to keep birds etc away. What you need is a pepper pot cover that sits in the chimney pot.

I'm only adding the extractor flap (it didn't come with one!) because the plaster put in its place was covered in dirt when I removed it. I need an other chimney pot too, so I'll get someone to fit both at the same time.

Thanks for all the help.
