Why do wall ovens take so long to preheat?
Comments (12)Why do [wall] ovens take so long to preheat? Because they are trying to heat 3.5 to 4.4 cubic feet of a very poor thermally conductive/susceptible material - air. Simple physics really. Are you looking for an oven to BEEP in 6 minutes? Or to preheat in 6 minutes? Most (not all) conventional ovens will beep at you in about 6 minutes. But neither your ovens nor Trailrunner's ovens are actually reaching 350 degrees in the center of the oven - where you're doing your baking - in 6 minutes. I'm sure they are most quite reliably recording 350degrees in 6 minutes centimeters from the broiler element where the sensor is located, however, that causes the oven to beep at you. ;-) Otherwise, I agree with Trailrunner - the smaller the cavity, the faster it will preheat. For frozen pizzas, a small toaster oven is not a bad thing to have. I think my cuisinart convection toaster oven is ugly as sin. But I've kept it and I use it regularly for heating and even cooking smaller quantities of food. Seriously no sense heating up a large cavity if you're not going to do justice to it. Good luck....See MoreAdvantium 120 OTR Preheat times & other Q's
Comments (1)I use a microwave convection all the time. I've never considered preheating to be an issue. I might add a few minutes to the overall cook time if I start from a cold oven, but that's about it. I bake potatoes, rolls, etc. I reheat pizza (set to about 375* and wrap the pizza slices in foil, go for about 15-20 minutes). Hotter temps require longer to preheat, but certainly no more (and usually less) than the large oven. It is not a toaster. Toast bread elsewhere. I don't have to wait for it to cool down to use the microwave, but I do some anyway since the interior is hot. I usually use a metal rack to hold food off the bottom and that thing will be hot to remove if I don't let it cool a bit. YMMV....See MorePreheat time for the convection elec oven in your prostyle range
Comments (0)I have an opportunity to purchase a 4 year old 36 inch DCS DF range for $2000. I went and cooked on it yesterday, the gas top is wonderful, but the oven took over 25 minutes to preheat.My current 27 inch double GE profile convection wall oven takes 15 mintues to preheat (I timed it when I got home). I am now thinking that I will keep the double wall oven and look for a prostyle drop in rangetop instead. But, the food I cooked yesterday was delicious and I think that the broiled chicken fron the infrared broiler was better than I get in my GE oven. So I am torn. I was wondering if this preheat time is typical for this size pro style range. what do you think of the price? Also, does a broiler need to be preheated? thanks!...See MorePre-heating oven question
Comments (27)The thermal dynamics inside an oven is extremely complicated. There is heating by convection, conduction and radiation occurring simultaneously. It all depends on the construction and the design of the oven and the food that is being cooked. Preset preheating of the oven is highly inaccurate given the fact that the outside temperature of your kitchen also plays a part. Of course you all know inside temperature varies depending on the placement of your food. If you want an accurate instant reading of the temperature on the surface of your food or deferent areas of your oven, a non-contact remote reading thermometer is not that expensive. dcarch...See Morefoodonastump
