Jenn-Air induction cooktops, available at 30 and 36 inch widths, feature a number of benefits. The chief advantage of this style of cooktop is that, through induction cooking, only the cookware is heated, leaving the surface of the range cool to the touch.
Jenn-Air induction cooktops, like all brands of that type, work by creating a strong magnetic flux that interacts with steel-based cookware to heat a pot or pan through resistance. Non-magnetic cookware made of copper, glass and aluminum is heated on a ferromagnetic interface disc that acts as a conventional hotplate. Induction cooktops have an average efficiency rating of around 90 percent higher than electric or gas ranges.
In addition, Jenn-Air includes features a sensor boil function that measures water temperature and audibly alerts when water is near boiling. The sensor also adjusts temperature after the water starts boiling to prevent messy boil-over. The 30 and 36 inches models also feature bridged heating elements; the former has two hotspots linked, while the latter has two sets of two bridged, effectively creating a single large cooking zone useful for cookware, such as poaching pans and griddles.
Other benefits of the Jenn-Air models include separate element timers, pan size detection and low-heat cooking functions for simmering. They also have one-touch off features that quickly turn off power to the cooktop with an audible confirmation signal.
