Extracter hood outlet problem

[kelfoan]

We are in the process of having a new kitchen. The current kitchen has a vented extracter hood. Only problem is that the vent goes through the outside wall and into the conservatory! Obviously the previous owners had the conservatory added later with no thought for the extracter outlet. I don't particularly wan t all the smells pushed into the conservatory, but am worried that a recirculation hood would not be powerful enough. I cant see where a new extractor outlet could be made as the conservatory covers the entire back of the house. Any one got any idea!

why have one at all, the people i know went mad for one and now never use them, they seem to look good, but do very little other than make a noise, the only ones that really work well are commercial ones, just something to think on!!

Can you not pipe it through the conservatory to the outside world ?
Maybe by turning it 90° upwards and up through the roof, or perhaps 90° to the side and out a side wall ? Box it in if you must.

I've not had a lot of experience with hoods, but don't the circulatory ones filter out smells anyway, with you just needing to replace the carbon (or whatever) filter from time to time ?

Seems to me to be a design error if there is no outlet to the outside world from your kitchen. What no window to look out of ? No accounting for previous owners I suppose.

I thought about piping it out of the conservatory window, but this means taking out a sealed unit. Not sure of the work/cost involved

I've given it some thought but I can't come up with an easy alternative - sorry.
I don't agree with WW's assertion that these things merely make noise - he perhaps has bought only cheapo ones. These things not only extract smells outside but more importantly extract water vapour from the hob straight outside, at its source - an important point as evidenced by the number of folks whining on about condensation on their walls in this cold weather. Failure of extract from open, boiling pans is exactly why this happens.
I admire OG's creative solution but would have the same concerns as you - if your conservatory roof is glass DGUs it's a no-no, and if you had a hole cut around in the plastic polycarbonate roofing types, I'd be concerned about creating water leaks around the join - polycarbonate expands and contracts a lot with temperature variations. Besides, I think it would look naff.
Unless you have another external wall to the kitchen and could route the extractor pipework BEHIND the run of units (or above them - so you can't see it) to the area where a new drilling to the external world could be made?
I'm referring to use of this sort of stuff -

- which although it says is 100mm x 98mm in cross-sectionm I reckon is a misprint - you can get it 100mm x 50mm. That should surely go behind the units.

I've just had a recirculation one fitted that uses charcoal filters. It's really good.
