Just thought I'd update. In the end, I didn't go with the floor model, as I was concerned about how long it would last. I did go with the exact same model, but brand new. BIG MISTAKE and I will never buy Bosch again. Yeah, I get it... there's a pandemic and supplies are an issue, etc. OK, back up: The induction top stopped working a couple of months ago. The error that comes up is not listed in the troubleshooting guide, and nobody online seems to know what it is for sure. It was JUST outside warranty, but thankfully I paid with a credit card that extends the warranty by a year. HOWEVER, now I'm getting a runaround because they'll pay for the parts and labor to fix it, but the technician says the parts he thinks he needs aren't listed as an available part and I'll need a new stove. I'm in total limbo here and using a $50 single-burner hotstove in the meantime. So frustrating. Bosch said they had the part and $300 later all it was was a plastic cover for something that sort of sounded like the part the tech says we need. Sigh. Bosch says the error code isn't a "real" error code, whatever that means. I see other people searching for the same thing (the code is 0513 and you'll find various threads suggesting it has to do with being miswired, but this came with the cable factory installed and it worked fine for a year). So frustrating. Never again Bosch... never again. And, actually, even before it broke it wasn't that great. For being a "high end" and "professional" unit... it takes FOREVER to preheat the oven and doesn't bake any better/evenly than any cheap oven I've ever had. The controls are annoying to use. The induction was great (while it worked), but that's just a function of the technology not the brand/model. Minor, but the oven light was terrible. With the placement of it, it just sort of backlights everything so you get nothing but shadow. Overall, really not impressed even when it did work. $4000 wasted unless Visa comes through.

The upward velocity of induction cooking plumes can be lower than with gas cooking due to the gas combustion products aiding the gas cooking plume. This potentially reduces the needed CFM/sq.ft. for containment. (Not applicable to unintended flambes.) However, the expansion angle of the plumes that drive hood overlap may not decrease much. (I don't have time to look up the relevant paper at the moment, but will get back to the subject this evening, if possible.) Upping the CFM above that normally needed will slightly increase the effective capture aperture, and may be sufficient. If only low heat frying is intended, then that may help.

@r, I thought I would chime in here to just say that I don’t think you are “obsessing“ at all regarding the use of knobs in this case. One of the most crucial variables in any kind of industrial design is the way we interface or interact with whatever the product is. Most of us utilize capacitive touch controls or infrared type touch controls on a constant basis with everything from iPads, smart phones, as well as any number of house appliances. But I would suggest that your instinct regarding cooktop or rangetop controls makes a lot of sense. Consider the difference in using a wall oven versus a cooktop. Most cooks in the kitchen can get the opportunity to wipe their hands in order to use touch capacitive controls on a wall oven. Of course, the case could be made that turning a simple dial, can be more intuitive, then going through a series of menus to get to where you want to go, since in the end, the mission of the wall oven has not really changed very much since our grandparents time which is essentially to bake the cake or roast the chicken. The reason I suspect that cook tops and range tops, as well as ranges are a particularly good candidate for knobs is due to the fact that the controls are often placed on a horizontal plane. Many people, especially those who are new to induction appliances for example, have learned a hard lesson as the very sensitive touch controls do not always take kindly to steam, water, droplets, and oil or gravy splatters. It is not hard to imagine why this is problematic because if you put any of these liquids on top of your smart phone screen, you would discover that the touch controls that works so beautifully such as the ones I’m using right now on my iPhone to create this post do not take kindly to having these substances on top of them. There are lots of examples of folks who have touch capacitive controls on these horizontal locations where the entire appliance is either shut down or thrown off its game. Of course, the majority of modern products that have knobs do not use the analog/mechanical controls of knobs of the past, but are in fact, “knobs“ that interface with micro control boards behind them. Still, there is an entire field of design that studies user interaction, and I do think that, at least, in some instances, such as with cooktops, knobs actually, do make a lot of sense. One can certainly debate where the best location for those knobs would be to avoid getting splatters on them since Cleaning knobs is not exactly, a fun time for most folks. Some people would assume that installing Touch Sensitive controls in all sorts of consumer products that once used knobs, levers, and buttons, is simply a design trend, and I’m sure there is truth to that. But a little voice inside also suggests to me, that one of the reasons they have moved away from knobs and especially the electromechanical kinds used in the past, is due to the cost of manufacturing. I do not have a data set to support this theory, but if you consider the labour and the bewildering amount of copper wiring that went into something such as a 1950 electric stove, some of which had lots of extra features, you can begin to imagine the cost savings of having a micro “motherboard“ taking the place of all that complex analogue electrical structure. I truly enjoy all of the benefits and possibilities that I have with my smart phone, laptop, iPads, etc. But I do think your instincts for knobs are not without merit, because sometimes, appliance designers attempt to answer questions that no one ever asked. My two. Cents 🤔.

@itsourcasa yes we did purchase the Verona Induction. We've been using it for a few months and absolutely love it. Easy to use. And it is even so much faster and powerful than our vintage gas range which was really great. We don't miss the gas "power" at all - there is plenty of power with induction. Plus the clean up is so easy. No burners to clean out the spills.
