How the Five Compare on the Numbers
The five picks share one property: each maker publishes a width, a depth and a height. That is not universal on this sheet, and it is the reason for the shortlist. The Summit Appliance CR5B36T9B states 35.5 by 20.5 by 2.13 inches and a cut-out of 34 3/4 by 19 5/8 inches. The Karinear 36 inch states 34.25 by 19.3 by 3.07 inches and a cut-out that matches its width and depth. The VBGK 36 inch states 35.4 by 20.47 by 3.3 inches.
The two 30 inch picks state 29.5 by 19.6 by 3.0 inches for the Nefaracy and 29.13 by 19.3 by 1.73 inches for the Noxton five-burner. Weight is published for only two of the five: 40.0 lb for the Summit Appliance and 32.0 lb for the Karinear, an 8.0 lb gap. The other three makers do not publish a weight, and I have left those cells blank rather than filling them in.
The table does not tell you whether a unit will sit flush in your particular counter, because flushness depends on the cabinet and the counter thickness as much as on the panel. It also does not settle the Noxton question: that listing gives a panel size of 30.31 by 20.47 inches in its text while the fields say 29.13 by 19.3 inches, and the maker does not say which figure is the panel and which is the opening.
Reading a Cut-Out Figure Before You Cut
Where the maker states an opening
Three of the five state a cut-out. The Summit Appliance gives 34 3/4 by 19 5/8 inches, and its panel is 35.5 by 20.5 inches, so the glass overlaps the counter by a fraction under an inch on each side. The Karinear gives 34.25 by 19.3 inches against a panel of the same width and depth, which suggests the figures describe the opening rather than the glass. The Nefaracy gives 29.13 by 19.29 inches against a panel of 29.5 by 19.6 inches.
Those overlaps matter when the counter edge is close to a wall or a cabinet run. A panel that overhangs by three quarters of an inch needs that clearance on every side. The figures above let you check it before the counter is fabricated, which is the point of preferring a maker who publishes them. Where a maker states a cut-out in three figures, as the Noxton does, treat the third as the depth of the opening rather than the height of the glass.
Where the maker states only the panel
The VBGK 36 inch publishes 35.4 by 20.47 by 3.3 inches and no cut-out. That is still enough to plan a counter, because the opening must be smaller than the panel in both directions, but the exact allowance is left to the installer. The same applies to any figure you cannot cross-check. A panel figure without an opening figure is a starting point, not a cutting instruction.
For the two 30 inch picks the panel figures are close: 29.5 by 19.6 inches for the Nefaracy and 29.13 by 19.3 inches for the Noxton. The difference is 0.37 inches in width and 0.3 inches in depth. If your opening was cut for one of these, the other may not drop in, so the cut-out figure is the one to trust where it exists.
What Each Panel Does Beyond Heating
Burner layout and control type
The Summit Appliance lists two dual-ring elements, a 2200W 9 inch element and a 3000W 9 3/4 inch element, plus a center warming zone. The Karinear lists a dual-ring lower left burner and a triple-ring center burner, with an individual knob per burner alongside touch controls for the timer and lock. The Noxton five-burner lists a triple-ring element. Those layouts decide which pans sit where, and they are published, so they can be compared before purchase.
Control type is the other published difference. The Karinear pairs knobs with touch, which suits anyone who wants a physical dial for heat and a panel for timing. The Summit, VBGK, Nefaracy and Noxton list touch control only. None of these statements is a claim about how the controls feel in use, because nobody at Lush has operated these machines. They are what the makers publish.
Safety and timing functions
All five list a child lock. The Karinear, VBGK, Nefaracy and Noxton list a timer, with 99 minutes stated for the Karinear and the Noxton. The Summit lists indicator lights, a safety cut-off and automatic shut-off. The Nefaracy adds a pause function and an extended oval zone measuring 165 by 270 millimeters, for which no inch equivalent is published.
These functions are listed, not measured. A timer stated at 99 minutes is the maker’s figure. A residual heat indicator is a listed feature. What the listings do not say is how any of these behave over a long simmer or after a power interruption, and I have not invented that.
Which One Fits Your Kitchen
You have a 36 inch opening and a stated cut-out to match. The Summit Appliance publishes 35.5 by 20.5 by 2.13 inches and an opening of 34 3/4 by 19 5/8 inches, so the fit can be checked before the counter is cut.
You want knobs for heat and touch for timing. The Karinear 36 inch publishes 34.25 by 19.3 by 3.07 inches and pairs an individual knob per burner with a touch panel for the timer and lock.
You want a 36 inch panel with a touch panel throughout. The VBGK publishes 35.4 by 20.47 by 3.3 inches and lists nine levels on a touch panel with a child lock and residual heat indication.
You want an oval zone for fish and griddles. The Nefaracy publishes 29.5 by 19.6 by 3.0 inches and lists an extended zone of two heating components, with a cut-out of 29.13 by 19.29 inches.
You have a shallow 30 inch opening. The Noxton five-burner publishes 29.13 by 19.3 by 1.73 inches and a cut-out of 29.13 by 19.29 by 1.73 inches.73 inches.
What We Could Not Verify
Several figures a buyer would want are simply not on the sheet, and I have not filled them in.
- The weight of the VBGK 36 inch cooktop is not published by the maker.
- The weight of the Nefaracy 30 inch cooktop is not published by the maker.
- The weight of the Noxton 30 inch five-burner is not published by the maker.
- The Noxton listing gives 30.31 by 20.47 inches in its text and 29.13 by 19.3 inches in its fields, and does not say which is the panel and which is the opening.
- The Nefaracy oval zone is given in millimeters only, with no inch equivalent published.
- No maker on this sheet publishes a counter thickness range for its cut-out, so the allowance for a thick counter is unknown.
