Ceiling or Vented Hob Extraction - help please!!

3 months ago

Hey everyone,

We have recently finalised our kitchen/diner renovation project which includes knocking the dividing wall through. The new layout includes a peninsula with a hob. We currently have our hob against a wall with a traditional hood extractor, but as the hob will now be in a peninsula I am struggling to decide which extraction option is best and the different brands.

I was originally looking at a flush ceiling extraction with ducting to an outside wall, but am concerned that it will be too high to actually be effective. Most recommend a distance between the hob and extractor around 500-600mm. Our ceiling is around 2.3m.

I then came across integrated vented hobs which looked like the ideal solution, but have concerns that these options are not as effective and we would potentially have to look at recirculating units.

Can anyone offer any advice please? Any decent brands or specific models they have and work well?

Thanks in advance :-)

Get a realm overhead hood, with some capture area. Not the expensive and useless lies.

Sorry, I'm confused by the description. Do I correctly interpret it as describing a "done deal" that precludes moving studs, using rectangular duct between studs, making the cabinets above the hood shorter, or almost anything else that might have been options at an earlier point in the construction? kas

The code does not specify a specific location within the room, just the minimum CFM and that it must be ducted to the exterior. Just a word of caution if you are using an in-line fan to service more than one bathroom, when the fan is not in operation there is the possibility of odor from one bathroom entering the other bathroom through the common duct. I know they have dampers but they are not 100% air tight. Check out Panasonics Whisper Sense DC fans, they are extremely quite, powerful and they have a humidistat that automatically turns the fan on whenever humidity levels rise above a certain level.

Too bad that Futurofuturo's ceiling offerings don't conform to TH Kitchen's requirement (1), because that rule might actually be sufficient for a ceiling system. By "that rule" I mean that at eight feet the hood aperture would be 7 ft wide and 6 ft front-to-back or 42 square feet of baffles (and not slots or whatever FF is trying to pass off as a ventilation solution. For the baffles to be effective at capturing the larger end of the grease particle spectrum, an air flow of at least 40 ft/min might be necessary (unless some specially designed lower flow baffle was invented -- maybe the ball bearing filter approach would have merit in this case). So 40 ft/min x 42 square feet is 1680 CFM. This would require a 2400 CFM rated blower and probably 12-inch ducting. These baffles would need to be cleaned more often than normal commercial baffles (per quantity of grease vapor) because being flat they would have no drain and will otherwise drip grease. Just be careful to not fracture the cooktop or the counter reaching the baffles to remove them. 8 to 12 dishwasher runs should be sufficient for the baffle cleaning process, depending on how they might stack in the dishwasher. Non baffle ceiling solutions also work, but they require special techniques, such as UV breakdown of grease particles. For a full ceiling design, see for example the Haydal site: http://www.kitchen-ventilation.co.uk/heydal And the comment about drafts, from air conditioning diffusers or returns is a valid one, making the ceiling scheme ever more difficult to truly control. And don't forget that the MUA system has to match this airflow.

No vent at all achieves a more unusual trade-off solution within: Performance, aesthetics, affordability, pick two. Perfect aesthetics and affordability at the complete sacrifice of performance. Also MUA becomes unnecessary. The best way to keep a window view is bite the bullet and get a commercial-sized aperture hood, if the ceiling height will accommodate it. You can set the hood base at 7 ft above the floor. It should not interfere with sight lines at that height unless double height windows are used to view the sky. Someone on this forum reported avoiding the greasy window problem by setting the range out from the window by enough that the rising and expanding effluent plumes were entrained into the hood aperture without interacting with the windows. Obviously this solution requires a large enough kitchen in plan and elevation that increased counter depth and higher hood are practicable, and suggests that ventilation planning best occur before the house architecture is firm.

Induction for your hob will help. That method reduces some of the ventilation requirement by eliminating the waste heat from gas. Best Cattura is a downdraft vent that works better with induction. No flame to be affected. It will not be near as good a properly sized overhead. On a peninsula an overhead is also less effective than when you have a wall behind the hob. Then you can consider makeup air. Here's the marketing viewpoint.

thanks @Patricia Colwell Consulting I didn't even consider those.

@dan1888 we are going with an induction hob. I will have a look at this thank you

My Wolf Pro Island hood base is mounted 34.5 inches above the counter. This is equivalent to about 1.8m above the floor. The top of the hood, which is 18 inches (0.46m) is thus 2.24m above the floor. This plus a surround of sorts about the duct would fit under your ceiling, or you could raise the hood to be flush with the ceiling giving you a hood base a bit over 3 ft above the counter. Download the Wolf Design Guide from the SubZero/Wolf web site for dimensional parameters.

P.S. The cylindrical retractable hood shown above will have poor capture performance against higher velocity plumes. It needs some sort of inverted tray type attachment at the bottom that overlaps the cooktop by a few inches in all directions.

"Most recommend a distance between the hob and extractor around 500-600mm."

I don't know Mr. Most, but 30 - 36 inches (760 - 910 mm) is appropriate for properly overlapping residential canopy hoods, 48 inches for commercial hoods. Undersize, underpowered hoods may need to be closer, but they will only capture and contain from the rear burners/hobs.
