Hood dilemma : Range in front of a window and needs a vent hood.

last year

Hello,

I am doing an ADU project, and as per my city regulations, I will need a hood because I have chosen a range as a heating option in the small, linear kitchen.

Some basic constraints: This is an existing structure with 8' high ceilings (will remain that way), and the small linear kitchen AND the window in front will also stay that way (We are at a stage where we will spend $$ to change any of these constraints, though in hindsight these issues should have been hashed out. Anyway). Also, the sink plumbing is in place (in case it matters!).

We have a 24" cooking range (electric) planned here (again, this cannot change at this point).

I am trying to select a hood for this range, however, currently, there is an issue with that. As shown in the floor plan included, there is a large window in front of the kitchen counter and the range. This would preclude the option of a regular over-the-range hood or a cabinet-based hood.

We are considering an island hood, because it will look nice from inside and outside. We are having trouble finding many small island hoods. I have found one that might fit the bill, and my designer/contractor is recommending a circular hood -- which I will have a tough time getting my husband to accept, since he does not want to do off-beat things :-)

Any reviews/experiences/feedback on this company/specific product?
Are there any other island hoods you have had a good experience with, for small ranges?

Have you considered a flush mount ceiling hood?

You need a 30" island hood, with extra deep cabinets there, to pull the range away from that window's combustible surfaces. The hood needs to be wider than the range under in for better capture.

Recirculating range hood vs externally vented hood

A recirculating hood that cleaned the air of grease and odor to the level of the fresh replacement air resulting from use of an exhaust hood would be very large and likely fairly expensive to replace filters for. It would require a series of mechanical filters for different size ranges of particles, as well as charcoal filters for odor. The stack of filters would require a blower capable of the desired flow rate in the presence of a significant pressure drop. This would be noisier than a similar flow rated exhaust blower. Such a system's size would only be justified in some context where exhausting cooking effluent was prohibited. I am unaware of any units sold for residential purposes that would meet my sniff test, but there may be some somewhere. A search on this forum might yield a link to a thread I recall where someone had found a unit that met his sniff test. There could also be commercial versions available. On the plus side, recirculating systems would not need make-up air. kas

Venting of Range Hood Dilemma

If you don't have proof that you sent the specs to the GC, ask him to show you the specs that he did use or show you where he found the 21 1/2" maximum height recommendation. Don't let him tell you that he could use any height he wanted in the absence of instructions from you; he should have asked. Vent-A-Hood says the recommended mounting height for their under-cabinet hoods is 21" to 24". For their wall-mounted hoods they recommend a maximum of 30". They also say that exceeding the maximum recommended mounting height may compromise performance. A range hood is not a gas appliance vent but an exhaust for cooking vapors, so there is no code requirement to have one and the installation height is entirely optional. Some homeowners are tall and prefer a hood mounting height greater than 30 inches and are willing to give up some cooking vapor exhaust performance. (I think of this every time I hit my head on the sharp corner of my brother-in-law's hood.) Therefore the height of a range hood should not be determined by the maximum recommended height in the installation instructions but by the design documents. So, the GC should have asked you what height you preferred regardless of what manufacturer's installation instructions you gave him. If the GC designed the house and prepared the construction documents, perhaps he thinks he has your permission to make such decisions on his own.

Range & hood in front of window - great idea, or terrible idea?
Q

The particular hood shown above appears to have traded minimum view blockage for reduced capture and containment capability -- the two functions that a hood is intended to perform above all others. I suggest determining where adequately capable hoods can be installed in the kitchen that don't excessively block desired views and which allow proper ducting to the outside. Then evaluate placing the range under those candidate hood locations with the rest of the kitchen layout adapted to that configuration. Perhaps one of the resulting layouts will meet most requirements. Island and peninsula locations for cooktops require relatively obtrusive, larger hoods with commensurate higher air flow rates due to having all four sides of the rising effluent path open. kas

I rechecked the specs yesterday I gave him back in October and they are the same install directions and measurements as what came with the unit. I think the problem is our builder is a custom builder who when we signed him on to build our home only built a few houses a year, but now in the year since construction started on our home he's building over 20 houses a year and commercial construction as well. He is not there to check the houses at each stage and make sure each house is being done to the custom choices that are spec'd. During our build we had to have him fix several mistakes or add things he had forgotten. He still only has the one GC to help him on all those houses. I think he either needs to decide to build either cookie cutter homes all the same or have more site supervisors to make sure the custom work is being done correctly at each stage. The frustrating part is that we the home owners should not have to time and again tell him he is building it wrong when the specs are in the contract, on blue prints, on spec and install sheets and most decisions were also talked about and walked through at the house with him at each stage. We have been very polite and patient during this time with him but very firm we want our home to be finished properly. I think he said he never got the specs as it was the easiest thing to say since the unit came only on Friday and the specs were given way back in October and he never made sure the duct installer followed the instruction specs at install. I'm sure he remembers as he was pretty insistent we had our appliances chosen and the specs given to him to give to the trades at framing. I can't wait till our home is finished with this builder and I can let it go but in the mean time we have a long way to go and I just want to make the best decisions on how to make our home come out well given the circumstances and our too busy builder.

@JP L, I have considered it and currently that is a Plan B. The main reason is that I found it to be difficult to get info on flush mounted range hoods. If you do know any good brands, please share.

@User: Thank you for the advice - but custom sizing is not a route I am interested in at this point.

You do not need custom sized anything to do extra deep counters. You just need a custom installation. You mount a 2x6 on the wall, and mount the cabinets to it, giving you the required clearance to the combustibles. You just need a right sized skin for the end panel where the cavity is exposed.

Let me emphasize a comment above: For greasy plume capture the hood has to overlap the cooking area because the cooking plumes expand as they rise. This requirement leads to rectangular hood openings, not circular openings.

For examples of island hood sizes, you can review the Wolf Design Guide, available at Subzero Wolf's web site. Also, a tour of AJ Madison will reveal probably hundreds of options, perhaps less expensive. Keep in mind one almost never gets more than he pays for.

Flow rates (CFM) to assure containment are based on the same parameters as published here in numerous hood related threads.

A properly sized hood with adequate CFM should minimize the need to clean windows and walls behind the hood. Climbing on stone counters, if used, should be avoided in any case.

@homey_bird - My BIL has this one (noted for the brand/line, not necessary the size/specs as they may not fit your application - consult a pro on that!): https://www.prolinerangehoods.com/ceiling-flush-mount-island-pro-42-range-hood

For what it's worth, the installation was a bit of a struggle for them, but once installed, they are very pleased performance-wise. My SIL is an avid cooker/baker/entertainer; the unit has been installed for several years now, and is used daily with no issue.
