Most powerful cooker hood

[chopc]

Any recommendations for the most powerful integrated cooker hood? Thanks in advance

look at elica - they may have one

I looked on here
www.cookerhoodtests.com

We are going for a Stoves one as wanted something energy efficient.

Westin if you want to spend

We have a Faber one and it's pretty good.

Is the cooker on an outside wall?

How high is the ceiling above the hob?

Is there a row of wall cabinets? What height?

Thank you for your responses.

@PigletJohn
The cooker will be on an outside wall as I think if you extract out you reduce smells more?
It would need to be at least 100cm wide.
I saw a Luxair one which has an extraction rate of 950 but ideally I want one that could be integrated into a row of cupboards
Thank you for any advise

OK

You can have a canopy type that can be fitted into a cabinet matching your wall cabinets

Depending what your ceiling height and your wall cabinet height is hou will hopefully be able go align the top of the canopy with the top of the wall cabs

The canopy should be high enough that you are incapable of banging your face on it when you stand at the hob.

Something like this perhaps

elica.com/GB-en/hoods/era-lux

The "works" of this one are up to 800mm wide but you can put it in a bigger canopy box. Or you could have two at 500mm but I think the switching would be inconvenient.

You can see from the dimensioned drawing that the exhaust spigot comes out of the GOP, you then connect it go the duct through the wall with an elbow. Modern powerful extractors have a duct size if around 150mm diameter.

There is a very large range.

See also elica.com/GB-en/hoods/hidden

And the Elibloc and Eliplane.

I am pleased to see that Elica have improved their website now, but ask them to send you their glossy brochure which makes it easier to choose and compare the different models.

I favour one that will fun quietly on low speed but can be turned up when necessary for greater power.

Look at the noise in DBS and the flow in cu.m/hr and compare those figures to other manufacturers you look at.

John Lewis carry a selection of the range but there is at least one supplier that can get any of them.

Look at www.tlc-direct.co.uk/Manufacturers/Elica/Built_In_Canopy/index.html for examples of prices.

GOP means "top"

If I had the budget, I’d get a BORA hob with downdraft extractor.

Thank you. As per my calculations we need an extraction rate of at least 792m3/he. I don't think Elica do ones that powerful

www.tlc-direct.co.uk/Products/ELB80RM.html

Up to 1200

You have a chip shop?

Table 5.1.A

30 litres per second is 108 cubic metres per hour.

Thank you. So the room is 4.4m x 8.1m and I assume ceiling height must be at least 2.2m

So I thought extraction rate should be at least 4.4x8.1x2.2x10 which is actually around 780

I like that Elica one @PigletJohn . But was advised the width should be at least same as the job? If so need at least 100cm as I will have modular hobs

The large room size gives a curious calculation.

If you have a huge fan sucking the air out, the room will be rather cold and draughty.

Provided that the room is not windy inside, the steam and hot fumes will tend to rise up from the hob. In the absence of an extractor they would then spread across the ceiling in a cloud (which is visible if the room is cold) then diffuse into the atmosphere as they cool.

I'm thinking of a large canopy like an inverted tray, so the steam and fumes are caught by the borders, and cannot escape sidways, but are sucked out by the fan. The extractor in the canopy need not be as big as the canopy.

Some of the extractors used in chip-shops and comercial kitchens work something like that, there is a large bin that the fumes pour into (upwards) rather in the same way that you might hold a bath or a sink under a splashy leak in the ceiling, and the water would run away down the plughole.

The hoods where the motor and fan are mounted outide the house, on the exhaust end of the duct, will be quieter than the normal design where fan and motor are inside.

Thanks a lot for your explanation @PigletJohn

I have an idea that @johnd2 assembled a special extractor, he may have an idea.

Thanks piglet John, yes you won't need 700+m3 fan that's excessive unless you have a room full of Hobs.
Anyway to answer the question yes i built a custom hood by buying a top cupboard, cutting the bottom out and a hole in the top, and fitting a huge inline fan and a galvanised metal hood underneath. It's all hidden by the cupboard and the only ugly bit is the switch (that was function over form in the end)
It could easily be ducted out but in my case i built a special bracket to hold a restaurant style grease filter and that catches most of the grease. Only an occasional wipe down of the cupboards that get the wind needed.
It saved a bit of money but it really was a custom thing with lots of tricky details, but i can give more details if you're interested in it.

Although sorry i guess that didn't answer the original question if that is what you wanted, i don't know the most powerful one as i wasn't happy with anything on the market that's why i custom built one!

@johnd2 that sounds very complicated.

So I don't think I need one that covers with width of the job in which case I can go fir the elica one suggested by @PigletJohn

Thanks both

it strikes me that if you had the canopy one mounted in a top-box, you could use pelmet or cornice round the edges to create the "tray" effect and prevent steam drifting out the sides or front. It's probably available in 100mm widths or thereabouts. Otherwise it could be done with matching strips cut to size.

You'd have to take this into account with the height, so you can't bang your head on it. The "works" inside the box, including the elbow, are quite tall, but may be out of sight if they stick out of the top. This has to be taken into the measurements before core-drilling the wall.

BTW I've also searched for 1000mm widths, couldn't find one, nor could the fitter. I got a 900mm.

Noted @PigletJohn . May need to go with chimney hood
