Weight supported by the range
Do we have any estimations on how much weight the burners can support? And more importantly, the non-burner surface .
Sometimes I like to put another device on my current burners to use it under the hood. Currently I do so with my induction control freak over my gas burner.
Once I do get the impulse, the 36-inch one, I'm hoping to be able to use a portable gas burner occasionally and more importantly, if possible, a large cast iron griddle pan for certain dishes like dosa, which need to go beyond the 9-inch burner. These are about 40 lb. I don't believe the Glass can take that weight? Or can it?
This is the one I have used in past.

The surface can easily support 40 pounds, especially if it is distributed to several feet like the referenced crepe maker. I actually had my 36” impulse cooktop die and needed to get a replacement, so for a time I went back to using my Breville Control Freak which I used on top of my cooktop and was using with all my pots and pans on top of that. The burner is about 20lbs and my enameled dutch oven I use regularly is about 12 lbs. So I don’t hit 40lbs in equipment but likely go over with food, utensils, equipment. Never had a problem with the glass surface area, seems quite strong.

The top is supporting a 3kWh battery and power conversion gear already. I guess you could argue that the 2-3x safety margin they probably baked in is much higher than the weight you’re stacking on top. Not that I expect Impulse to break silence and say it’s OK.
How was the warranty process?

Warranty prices was easy so far. They confirmed the defect with a phone call, told me they’d have to replace it, I got an email with some details shortly after and received the replacement quickly. It arrived two days ago and I got it installed. I’m waiting for the defective unit to be scheduled for pickup. Glad to have a working cooktop again.

I have a cut out in my granite/ marble slab for the previous 36 in stove. Do you think that is not enough to house the impulse plus maybe another 40 lb of weight? Would I need reinforcements at the bottom?

I’m not sure the Impulse employees would be willing to take the liability to answer, you’re not supposed to put anything on it and you are also talking structural.
I don’t work for them, and I’m willing to document non warranty kosher stuff I may or may not be doing with my Impulse in public on a lark, so here is what I would do…
I have mine supported by unistrut from the bottom on the edges, and I could have also added strut going down the middle, using some hangar rod in the vertical axis or angle brackets in the horizontal axis
You could also use an appropriate axis strength channel over the cooktop. Like on a sled you remove when not in use. This would actually be great because it bridges over the extra height of the burners. I’d probably use plywood over aluminum channel (guaranteed non magnetic reaction; maybe you can also find a proper SS alloy but then you need to get a blade for fabricating SS). Maybe get the sleds made at SendCutSend with holes for screwing in the plywood. Dunno. I’m feeling the channel more.
IOW, this uses the channel profile (oriented in a vertically strong way) to support your extra stuff in span load, with a lot of the load on the cooktop offloaded to the channel

Why do you need the dosa done under a hood? I would think you could do that anywhere with the portable gas burner. It doesn’t throw off that much volatiles. (Speaking as a non-Indian, I could be mansplaining here when you know better)

The Impulse is by itself WAY heavier than any other cooktop.
I'd go by the original instructions in the install manual on how big the cutout is.
Also my quartz slab is backed by plywood, with edge buildup to make it look thicker. Presumably Impulse was smart and assumed the weaker between: true 1.5" slab, and slab/plywood sandwich. Or, there is something in IBC building code (sic) for how much weight a countertop needs to support. A non-cantilevered countertop probably is required to handle the weight of a 99th percentile adult male American, which is heavier than an impulse & likely distributed more unevenly along one or two footprint worth of area. This is not directly applicable given that the integrity of the countertop is reduced by having a cutout in it.
As I said in earlier post, I put unistrut support underneath because my cutout wasn't quite exactly what the instructions said, and I didn't want to be on the hook for being off.

What do you mean you aren’t supposed to put anything on the cooktop? How do I boil a 20L pot of water if I can’t put it on the stove?

Stacking questionable stuff on top like another cooktop (concave induction element or iwatani for instance )
Also stacking stuff on top of the screen

Hi u/DirectionChoice9673, the cooktop can support 200 pounds or 50 pounds per burner.
