Extraction dilemma!

4 years ago

We need some advice and help on extraction for our open plan kitchen/diner/lounge - we are having a 5 burner gas hob in an island (only configuration that worked as sink in Island was considered too messy). We were looking at ceiling extractors that could handle a range of cooking (Mediterranean, Indian, Wok, etc) and were recommenced Gutmann or Westin. Does anyone have experience of using either of these with a more "active" kitchen where keeping cooking smells off the furniture and clothing was a consideration? Another brand mentioned was Falmec?

An island (ie a drop down type) extractor would ruin the design of the room (clean lines, flush ceiling through out, rooflights close to the Kitchen area, etc). We are hoping to duct out - our ceiling void space is about 245mm where the extractor would be sited.

The overall open plan room space is 9m x 5.5 m and 2.6m ceilings with a flat roof above the Kitchen. We have rooflights (one between the Island the Kitchen wall run) which made things more challenging .

Advice urgently sought (and hugely appreciated!)

Bora cooktops are the only way I know of having 100% clean rate.

Just as an alternative you could look at a French style door. It will still give up that grown up feel. I would definitely opt for painted rather than wood, something that doesn't contrast with the wall too much so they're not imposing but still remain a feature. I can't see the furniture properly but it looks as if it would go. Btw my brother recently had wood wardrobes installed probably about 10ft long and they were 5k. He used the company who manufactured and installed his kitchen in the end but the quotes were all around that mark or higher (ouch!). Layer the bed with cushions and throws and at least you'll get that feeling of calm and tranquility!

Definitely put the shower room on the left. Because:- The shower room is a smaller intrusion into the traffic flow through to the kitchen than the living area is. The middle of the house only benefits from a modest window which should not be given to a shower room that only gets occasional use when a main reception would have to do without. The reception has more privacy from the front door when situated on the right. The shower room on the left can easier be used by upstairs bedrooms if it is closer to the base of the stairs and users wont have to go past two reception spaces to use the extra wc. Assuming you choose one type of flooring for the reception room and another for the hall and shower room- the shower room on the left offers more continuity of flooring. The left hand side is almost certainly under the main bathroom and soil pipe which offers some cost efficiencies.

It's completely up to you and what you feel looks right. Obviously the closer the extraction the better it will work and 750 is the usual distance from the cooktop. However, if you prefer the higher bridging unit, that will be completely fine too as steam goes up! good luck Emily x

If you are not going to use an extractor over a hob then you only need to put an xpelair style extractor into the outside wall to meet regs.

Thanks gents. I did I see the Bora products at the grand designs show, though they are awfully expensive - well out of budget! Plus for ducting out, that would presumably require towing up a lot of space in the island itself?

The bora takes up the top drawer but the drawers below remain full depth in most kitchen island situations.

The Bora is a premium product but since a ceiling extractor can cost £1600 and you can also spend the same again on a hob it is not more expensive than other premium ways of delivering a hob and extractor- the difference is that they are very, very quiet (versus typical 70bd ceiling extractor) and boast a 100% clean rate.
Separately they can be recirculating so you can use them in passive houses and they don’t have to extract.

The makes you have mentioned are all good in my opinion. Ceiling extractors - in fact any extractors - are only efficient if you turn them on as you light the gas - ie to set up a good air flow out from as soon as you start cooking rather than waiting until thing start to bubble ! It’s also useful to keep them on for a while after you stop cooking. So My advice would be go for the most efficient and quietest one in you price bracket. It’s worth spending money on this once - rather than buying cheap but then having to buy again as you realise that you can’t chat while you cook due to the noise ! Extracting vapour and smells is even more important in an open plan space - as you don’t want your soft furnishings absorbing your cooking smells .

There is a calculation for how much extraction you need to keep grease and smells out of the air and out of your furniture. Basically you need to filter the total volume of air in the room 10 times per hour which for your room means extracting 1300 square meters per hour.
Most ceiling extractors extract 700square meters per hour- also their efficacy is reduced when the builder insists on putting in a vent that is too small (almost always they put in 12cm instead of 15cm so this is 50% smaller). The efficacy is also reduced if the extraction pipe is long or has bends in it.
So basically to effectively extract in a large room you either need three overhead or extractors or one downdraft one.
I get that on the face of it there seems to be a cost disparity but if you want clean air this is what you have to do.

I have a Siemens down draft extractor hob that works well if you something to match other units. It gets rid of most of smells and we open the roof lights on a warm day. We have an open plan area too.

Thanks everyone.

We have been advised by kitchen designers to go with a Gutmann ceiling extractor that extracts at about 950m3/hr and is apparently the best in the market (apparently Westin is similar but effectively is replicating the Gutmann product).

We have looked hard at the Bora range and whilst it looks amazing and seems to work very well, we remain confused as to whether their combined all gas (we need all gas as both of my parents who live with me have pacemakers - which we are told means we cannot have induction?!) and extraction unit would be appropriate . The cost is truely eye-watering too!

So it’s down to the Gutmann or Westin. Wondering if anyone has direct experiences of these?
