Final stages now before i order our new kitchen.

We are having a large island in the middle which will have the hob in it. Im struggling to work out what extractor to use as when i look on line it appears may people don't actually have one on their island even though the hob is there.

Ive been told i could have an inline extractor fitted into the bottom of one of the wall units (approx 2m away or so from hob), duct it straight out of external wall. Nice and powerful and I'm sure effective but not next to the hob so I'm unsure on how well it would work, would grease end up all over that unit? Obviously very cheap to do as well.

Pop up island extractor. Always been what I've assumed ill get but how good are they? they take up a fair bit of space and also are very expensive. Im sure the novelty of it popping up wears off as well.

extractor fitted in ceiling. Wont work due to joist lay out and wont be able to duct out.

extractor hanging from ceiling, not keen on the look due to the design of kitchen.

So either downdraft or a hidden inline filter in a cupboard. What do we think?

Its the only place for it really, I've racked my brains for months trying to configure different options but would only really work here. Only other place it to have hob in front of window and have sink on the island but i think thats an odd layout imo.

I think i can duct outside but it wont be that easy. Im almost more concerned of how big they are iykwim. They take up a lot of space on the island and are a lot of money.

Ive seen the hobs with the extractors built in but you lose that much cooking area and they appear in the drawings to take up huge amounts of space under the island (although they may not be an issue).

A dropped ceiling would work but all the extractors seem to be at least 250mm deep or more. our house is a mid 80's bovis and so ceiling height is on the low side anyway. due to joist direction as well the housing for the extractor would have to run off to the window wall to extract out making the whole thing huge and potentially odd.

umm maybe ill stick with the pop up extractor then. Im starting to wonder though if ill even be able to vent it out properly, ill have to dig up the floor screed which is about 80mm thick and can't go any lower.

Im not sure if one of those rectangular vent pipes would be ok, suppose better than recirculating.

Its a decent sized but really awkward kitchen to do a design for. Effectively only got 2 walls to go against, one is internal, one is a external with window.

If the ceiling joists ran the other way it would be a lot easier to duct out with a ceiling extractor. Or i would have to make some bizarre looking dropped ceiling which had to run to outside iykwim.

Yes 80mm is very very tight and i just don't think it would work properly.

Thinking about it i could use a ceiling extractor built into a dropped ceiling and vent out the way the joists above run. It would not be easy but id have to:

Build a dropped ceiling.
run duct over to the wall punch through this wall and then go into the roof space of that room and then into a roof tile vent.

The room is open plan to the kitchen and was closed off, is single story and has had the supporting wall removed and a steel put in place. Looking at it i reckon it might well work, id have to find a roof vent capable of taking 150mm duct.

May well be more effective than trying to get the downdraft to work properly.

Interesting about the extraction getting worse, i fear my idea of ducting several meters with various bends might just be crap.

Maybe ill just stick to a recirculating design and then fit an extra inline fan within a cupboard if it doesn't clear the air well enough. Been doing my head in for ages trying to decide whats best, as its a balance of performance, looks and cost.

Ive found an ex display one of these, apparently no marks etc looks good as well (if your into that sort of thing)
