stepheni Posted September 2, 2017 Share Posted September 2, 2017 We are installing an island in our new kitchen with an induction hob on the island. My wife doesn't want a large extractor hanging down over the island. Just wondering what the options are for ventilation in an open plan kitchen area. Looked at building a dropped ceiling area over the island to house a flat ceiling mounted extractor but it seems a very expensive option. Alternatively looked at a wall mounted unit but not sure how that will look aesthetically or how effective it would be away from the hob. How would you even switch it on/off. This is a new extension to a renovation project so no MVHR installed. Anyone any suggestions? Link to comment Share on other sites More sharing options...
Ferdinand Posted September 2, 2017 Share Posted September 2, 2017 (edited) You can have an opening in the roof like Asterix . Alternatively, there are extractors which suck the fumes down through grills in the worktop, and a few people here like those. But they are not cheap either. Someone will be along in a minute who knows about them. Ferdinand Edited September 2, 2017 by Ferdinand Link to comment Share on other sites More sharing options...
Guest Alphonsox Posted September 2, 2017 Share Posted September 2, 2017 We had the same problem - the answer for us was one of these.... https://www.bora.com/en/bora-products/bora-basic/ Link to comment Share on other sites More sharing options...
Oz07 Posted September 2, 2017 Share Posted September 2, 2017 Couldn't believe how expensive those flat ceiling ones are. Do look good though Link to comment Share on other sites More sharing options...
Declan52 Posted September 2, 2017 Share Posted September 2, 2017 I done a similar thing in my kitchen. It was just a sheet of 18mm MDF with a bit of stud to make a frame. Plenty of big screws to hold the studs to the underneath of the joists. I put some down lights in it to shine light on the island and a colour changing led strip around the edge. The extractor fan is just a normal type you would put in any built over type unit. All in including the fan it was approx £250. I have the fan wired into a switch on the wall so just gets turned on here. 3 Link to comment Share on other sites More sharing options...
lizzie Posted September 2, 2017 Share Posted September 2, 2017 Bora has the integrated extractor, that is what I went for. Fantastic piece of kit. Think Siemens have brought out a cheaper version now. Link to comment Share on other sites More sharing options...
Ferdinand Posted September 3, 2017 Share Posted September 3, 2017 (edited) Decided I needed to know about these, so I went looking a little. Boras start at about £5k iirc for the "Bora Basic", though I think that includes the hob too. Apologies for food porn video at bottom. Personally I might baulk at that, as it equates to £1 per meal spent on the capital cost of the extractor hood / hob if I use it 10 times a week for a decade (!), and I would prefer one or two extra ensuites. But people who have them, love them. Correction: Actual prices for Bora Basic start at around 2k-2.5k. My 5k is wrong. Siemens brands have things such as the Siemens LD97AA670B Downdraft Cooker Hood which comes out of the worktop like a James Bond television, at a little under £2k. Very cool. Vid at bottom. There are also a Neff one at about £1500-£2k: https://www.johnlewis.com/neff-i99l59n0gb-downdraft-cooker-hood-stainless-steel/p1629490?sku=233668456&s_kwcid=2dx92700024773953252&tmad=c&tmcampid=2&gclid=CjwKCAjwranNBRBhEiwASu908JZzOAr5z6j3NN4yrp5H2vVuyZQCPb4yDShkFUW9TvjVJLM-cM0ZexoCByUQAvD_BwE&gclsrc=aw.ds If Siemens and Neff are in on it at that price, then there will soon be occasional offers at under £1000 for those at places like Curries and Applicanes Direct. Aha - I see that Appliances Direct already have a Smeg one (another Siemens brand) at £1200, and a Miele (also Siemens iirc) at £1600. http://www.appliancesdirect.co.uk/ct/cooker-hoods/downdraft-extractors If you are taking a couple of years to build, they will be rotinely under £1000 if you look and can accept one of those brands. And there are a couple of cheaper ones from lesser known brands: B&Q £592 - http://diy.com/departments/cooke-lewis-cldh-14-stainless-steel-downdraft-cooker-hood-w-900mm/291234_BQ.prd Flavel £430: http://www.shipitappliances.com/cooker-hoods/90cm-cooker-hoods/sia-dr91bl-90cm-touch-control-downdraft-black-kitchen-cooker-hood-extractor-fan?gclid=CjwKCAjwranNBRBhEiwASu908K441DOmm57S6DxnWVYj2TRAIh2FvjFDN7t4ueZoWZYHvZB_pFQgQhoCR8cQAvD_BwE Ebay deal: £350 (like the look of this) http://www.ebay.co.uk/itm/MyAppliances-REF10219-60cm-Downdraft-Cooker-Hood-Extractor-Fan-Stainless-Steel-/272765613569?_trksid=p2141725.m3641.l6368 Capel £640 https://www.appliancehouse.co.uk/shop/Caple-DD903BK-Downdraft-Cooker-Hood.html?utm_source=GoogleBase&utm_medium=XMLbase_feed&utm_term=Caple&utm_campaign=DD903BK&gclid=CjwKCAjwranNBRBhEiwASu908GpFXdPg27RifOmJMOLdbtyN_nEZR9zZW8RA7i0_iAmCF8x_118TOBoCO6wQAvD_BwE Edited October 9, 2017 by Ferdinand Link to comment Share on other sites More sharing options...
Plumbersmateuk Posted September 3, 2017 Share Posted September 3, 2017 I'm following this and what concerns me is the quality, reliability and noise levels of the cheaper ones. I mean from £500 to £2000 makes you think? On the siemens site it shows the fans used, better than the ones in my current Bosch hood Link to comment Share on other sites More sharing options...
Ferdinand Posted September 3, 2017 Share Posted September 3, 2017 (edited) Also bear in mind that for an island you will need to design the extractor ducts into your slab - or mess about with stepped floors etc. Also, there are length limitations on the ducting. @Plumbersmateuk Agree entirely. So where is the centre of the ball? Each cross wrongly placed will cost £100-£5,000. Ferdinand Edited September 3, 2017 by Ferdinand Link to comment Share on other sites More sharing options...
stepheni Posted September 3, 2017 Author Share Posted September 3, 2017 Really appreciate the feedback guys. Unfortunately too late for ducting any of the downdraft type extractors as the floor slab and ufh is in with final screed being laid this week. I did consider these a few months ago but again discounted them due to cost and I suppose wrongly assumed a flat ceiling one wouldn't cost much, Declan - Whats the overall depth of the drop ceiling you have there. One of the kitchen designers suggested the same as you that putting a standard canopy extractor in works fine. I was concerned about the depth of the drop required as the extraction duct seems to sit on the top of the all of these type whereas the flat ceiling ones come out of the side. I only have standard 2400 ceilings so really wanted to keep the drop minimal. 1 Link to comment Share on other sites More sharing options...
PeterW Posted September 3, 2017 Share Posted September 3, 2017 I have an island with a 200mm drop ceiling over it as it also disguises the steel that was put in to allow the removal of a wall. As it's over the island you don't notice the drop anyway as you can't walk under it. Link to comment Share on other sites More sharing options...
Declan52 Posted September 3, 2017 Share Posted September 3, 2017 It is 300mm down. You could get away with more depth because the whole thing is white against a white ceiling so isn't very noticeable at all. Mine is out the top so in order to get it to fit I cut out a square in the gap between joists in my ceiling, I have attic truss but would work with any kind of joists. I put some 50mm insulation on the sides and top of the hole and to stop sound from going through to the room above. The duct comes out the top and then loops into the hole comes back down and then goes outside. Just make sure you buy a fan that is powerful enough. It's more important to take the steam away than be fancy looking. The flat ceiling fans I looked at where all up wards of £1k and the vertical type where even more expensive and I just couldn't justify paying more on a fan than I did on the hob, oven ,fridge and dishwasher combined. Google dropped ceilings and have a look as there are a lot of very nice looking ones. Any joiner worth his salt could make one very handy enough out of MDF.

Could plan B be something like a set of display or ingredient shelves at one end with a concealed duct to the ceiling from a downdraft extractor? May be less intrusive. Examples F.

You could even have 2 of those and run them at lower speeds so extraction rates were high but noise was low. Good for those who like to cook and chat / entertain.

RandAbuild Posted September 3, 2017 Share Posted September 3, 2017 We've got MVHR so I've been looking at a recirculating extractor. These tend to be a lot noisier as the motor isn't buried in the ceiling. Have researched what's available, we've decided on one of these http://www.applianceconsultants.co.uk/lux-air-la90verdestratoswht-recirculating-only-ceiling-hood-in-white-950m3h-8628-p.asp It has a lower profile than many ceiling mounted ones. They're all pretty expensive! Link to comment Share on other sites More sharing options...

This is in the same ball park as a decent induction hob and quality ceiling mount extractor. We have a two unit deep by three unit wide island with a 10 cm gap between the two rows of units into which the Bora fan exits. The exhaust then returns to the kitchen at floor level via a 10mm gap above the kick boards.

Good way to deal with that . Link to comment Share on other sites More sharing options...

Good way to deal with that . I'm hoping that will be enough, the Bora kicks out a serious airflow at full chat. If nessesary I can increase airflow with some holes in the backs of the units to allow air circulation around the draws Link to comment Share on other sites More sharing options...
Nickfromwales Posted September 3, 2017 Share Posted September 3, 2017 I think I'd want to discourage that from going through the drawers. Maybe just increase the cut to 14-15mm ? B&Q do a white plastic U section which has you can get to fit over the top cut edge. Easier than veneer and hard wearing too. Link to comment Share on other sites More sharing options...

I tend to agree regarding the draws - I may just sacrifice a single draw for use when on maximum boost if required. The 10mm was based on visibility criteria. We experimented with 15mm but it just looked like a bodged job with the gap very visible from all angles. Link to comment Share on other sites More sharing options...
Nickfromwales Posted September 3, 2017 Share Posted September 3, 2017 What about a piece of 40mm white L angle pvc bonded to the underside of the cabinet to give a white shadow then the reduced plinth in front of that ? That coupled with the white topped / veneered plinth should take your eye off it. Link to comment Share on other sites More sharing options...
JamesP Posted September 3, 2017 Share Posted September 3, 2017 Good topic as our kitchen has a vaulted ceiling, 4.5m high and we will have central island with induction hob. Similar size to Alphonsox. Looking at downdraft extractors, is it best to have recirculating than external extract due to having MVHR fitted?
