Which recirculating 100 cm extractor for cooker mantel?
Discussion
I know you said recirculating but...
If you're going to the bother of fitting one at all, why not engineer a solution to the water vapour extraction? (esp. if your hob is gas).
Heating stuff on the hob generates a LOT of water vapour and if you don't get rid of it, there's going to be quite a bit of condensation especially in the colder months.

What they said.
I fitted a nice shiny Siemens hood and as there was no easy way to get the fumes out I used it on recirculate. Basically useless. After a while I ran a 150mm diameter duct up and out from the side of the chimney at ceiling level to an outside wall a few feet away. Because the duct is matt white it looks very much like the coving on the other side, so effectively invisible, and it works brilliantly. Now I can be cooking and frying away and the pong doesn't even get out of the kitchen.
You have a mantel though which might make it trickier.

Thanks for the replies.
There's a mantle, then a 50cm dresser to the left, then 13cm gap to outside wall.
So it could go above the dresser unseen with a 10cm duct.
Ot through it with 15cm.
Bugger, just had it all plastered!
And there's an outside light exactly where the hole would go.

Is it on an outside wall? The you could go straight out of the back.
A neighbour of mine wanted to convert his cooker hood from recirculating to extraction. Being quite handy at DIY he marked the spot, got a suitable drill and set it on the wall. Then he realised that on the other side of the wall was his lounge

Building regs should not allow this kind of stupid.
But salesweasels will design you a kitchen with no proper extraction, then presumable sell you another one in a few years when the MDF digests itself.
They don't! An extractor is now mandatory in kitchens for new builds, extensions and major refurbishments. From memory in the past it was just the correct ventilation required based on opening windows and if there was an exterior door.

It’s when you see how much greasy gunk accumulates on the tops of cabinets in kitchens without an extractor and how much crap gets trapped in the filters of kitchens with a good extractor that you realise they’re a non-negotiable item. Absolute essentials if you’re serious about cooking.
I fitted two big Luxair extractors when I did our kitchen, I think something like 1800m3/hr total. You can’t close the doors when they’re on full whack and I suspect they’d reverse the flow of the log burner flue if I use them at the same time - the best things I installed in the new kitchen!

Ah yes.
When we removed the previous kitchen, it was covered in grease.
As if they'd been running a chip shop out o it.
The lack of an extractor venting outside explains it i guess.
I'll make sure it vents out of the wall.
it goes -
wall / 13 cm gap / 50cm dresser / 180 cm mantle
So i'll just feed the ducting through or over the mantle/dresser, depending how much height i have above.
Relieved i asked about this, as the mantle/extractor was going to be the last think i'd install.
Whereas it needs to be one o the first things sorted.
We have no rood for an explair, but have 2 windows and a roof window.

This is the kichen.
The vent would need to go on the right side, above right of the window. Top right corner.
Next issue.
There must be a lintel above the window.
Right at the level where i want to make the vent hole in the wall.
That little bit of wall to the right of the window is 30cm wide.
How wide is the lintel above the window likely to be?
Is it likely to go the full 30cm where i Want to drill?

We have a Luxair recirculation because our kitchen is in the original house and we have the stereotypical bifold box added to the back of it. Due to that, to duct it would have been a significant box over 8m to the nearest wall (semi so I'm not a PH director). I must say the extractor is excellent. You can feel it really sucking the air when on full and the filters get greased up but the tops don't. They're a UK company with good support too.I fitted two big Luxair extractors when I did our kitchen, I think something like 1800m3/hr total.

I would get a small drill and make a line of investigative holes from the wall towards the window until you hit steel.
Is there a roof void?
ah.Is there a roof void?
Yes.
Flat roof.
It's directly under where the airing cupboard in the bathroom above is.
The cupboard is empty as we moved the boiler.
But the void is only about 100 mm higg.
And going through that would man the vent goes straight into he side of the rubber roof overhang and guttering.
It's difficult when you run out of dimensions.
I had a towel rail fitted in my bathroom and that meant replumbing the c/h pipes under the floor.
A few years I decided that my cooker hood needed a duct, and planned to run it up into the ceiling and then horizontally between the joists to an outside wall. So I got a multitool and cut neat hole in the kitchen ceiling. I looked up into the hole and there was the new c/h pipe in the way - exactly where I wanted to put the duct. Arse.
