I also have a Jenn-air island electric cooktop. I'm sure the advice
regarding an overhead hood
being more effective is true. When I'm generating smoke, I can see
that only maybe 75% of it
is being drawn into the exhaust. It's just impossbile to effectively
suck air sideways from a distance.
Plus, I would think an overhead would draw less conditioned air out of
the house. You could have
the fan set on a lower setting and still have it be effective.
I'd have to disagree with the recommendation to stay with the electric
range. If you want to change,
do it. Most professional chefs agree that gas is best for the range,
electric for the ovens. That is
why you see many dual fuel options now. When it comes time to replace
mine, that is what I will
