Ranges, and especially wall ovens, nowadays with electronic controls typically have a cooling fan for the control panel that exhausts a larger immediate volume of heat into the room. In any case, all the heat generated inside the oven cavity during cooking must eventually dissipate into the room, short of having a closed-circuit outdoor exhaust integral to the appliance. Gas ovens need a bit more airflow through the appliance for O2 to burn the gas compared to electric ovens.

Hi Jerren. I have the 30" KA warming drawer model #KEWS105, panel ready. I have yet to use the slow cook feature as I keep forgetting it can function this way! I think I need to write myself a note and tape it to the front! I never use my crockpot as a food cooker because the pot isn't removable, and I hate cleaning it. The manual states: "When slow cooking, use serving pans (available for purchase) or oven-safe cookware." The serving pans shown in the picture and on-line are merely hotel pans sold very inexpensively at restaurant supply companies. My DH works for a restaurant supply co and laughed at the $99 price I saw online tonight for one of the KA pans. It seems you don't, however, even need special pans. Any oven-safe pan will work. Aside from this feature that I haven't used, I'm happy with my WD. I like the moist/dry function very much and use the unit at least a couple of times a week. Now to find a recipe with which to inaugerate the slow cook feature!

Have a kitchenaid BBQ and love it. Bought it 2 years ago and have not had a bit of problem. It was about 2000.00 , am not sure of model but I can check tomorrow. Its at new house and we are having work party and BBQ so I can get model # if you would like. It cooks wonderfully, have not used rotisserie, or smoker but am confident those features would be fine as well.

IMO rotisserie in a home oven is not a good idea. You would need to clean the oven after every use of the rotisserie and I guess it would depend on how often you need that function. I would never use one in my home but I love the one in our BBQ and use it even in the winter. I have an old KA double wall oven it is 15 yrs old and I have always loved it the cleaner works well and I love that the ovens do not heat up my kitchen since I use ovens a lot .
