Kitchen/Bath Industry Show Product Preview: Fisher & Paykel CookSurface gas cooktop

First there were electric smoothtop cooktops, which eliminated food-trapping coils. Next came gas-on-glass versions, which did away with the grime-trapping wells typically found around the burners.

The latest easier-to-clean cooktop is the 36-inch-wide, three-burner CookSurface gas model from the Fisher & Paykel. After you’re done cooking, says the manufacturer, you push a large knob on the cooktop to lower the burners so they’re flush with the ceramic glass cooktop, facilitating cleanup. Next time you need to boil water, sauté a steak, or stir-fry some vegetables, you push the knob to raise the burners. (The photo shows the cooktop with a burner recessed, left, and elevated.)

To lower or raise the flame level when cooking, you twist that same knob, says the manufacturer. The CookSurface cooktop provides smooth heat control by using the patented AeroBurner system, which adds oxygen as the flame setting goes up, according to Fisher & Paykel.

The three burners can go from a low simmer to a robust 15,000 Btu. Other features include digital displays, quiet igniters, and pan supports that rise and lower with the burners and replace the usual grates. The 21-inch-deep and 161⁄2-inch-deep versions of this cooktop should arrive at Fisher & Paykel dealers and select Lowe’s stores nationwide this fall.—Bob Markovich
