Double wall ovens have two separate ovens, allowing users to cook foods at two different temperatures. Some double ovens are quite pricey, but many are comparable in price to top-rated single wall ovens. Single-double wall ovens have two separate compartments in the same overall space as a single oven, while a true double wall oven has at least one full-size oven. This gives users a ton of capacity, but you'll need to have a larger space in your kitchen to accommodate the bigger oven. Most double wall ovens still measure 30 inches wide, but they are around 50 inches tall (compared to about 30 inches for single wall ovens).
The professional tests in our source list do not cover double wall ovens, so our recommendations are based on a consensus of user opinions. The best-rated double oven we found, the GE Profile PT925 (Est. $2,800) , is a single/double wall oven that measures 30 inches across and has a large five-cubic-foot overall capacity -- 2.2 in the upper oven and 2.8 in the lower oven. Users at Sears.com and Buzzillions.com say the oven fits all of their baking needs and does so in less space than a full-size double oven. The lower oven is big enough to roast a large turkey and to cook large quantities for entertaining purposes. One owner at Sears.com calls the wall oven "space, time and energy efficient."
The Maytag CWE5800AC (Est. $1,200) , on the other hand, is a true double wall oven. While it has a larger overall capacity than the GE Profile -- 2.8 cubic feet in the upper oven and 2.4 in the lower -- several users say it's small on the inside. That's because it's only 24 inches wide. One user at Buzzillions.com says, "My largest baking sheet won't fit in the top oven." Still, for some, the Maytag fits the bill because it's the only wall oven that will fit into their existing wall cabinets. The Frigidaire FFET2725L (Est. $1,700) is another highly rated double wall oven that has an ample 3.5 cubic feet per oven compartment and measures 27 inches across.
All three wall ovens get good reviews from owners for their reliable performance and even baking. Users say the GE Profile heats up quickly due to its smaller size -- the smaller upper oven preheats in as little as seven minutes. Users also say it doesn't heat up the kitchen like many ovens do. Reviewers have similar comments about the Maytag double wall oven, but several say that the cooling fan is a bit too loud. Owners at AJMadison.com praise the Frigidaire's looks and say that it's easy to install. Some say the timer is hard to set, however.
Of the three double wall ovens, the GE Profile PT925 is the only one with convection heating. It's also loaded with other features, including self-cleaning, broil, delay-bake, Sabbath, proof and keep-warm modes as well as a temperature probe in the lower oven. The Frigidaire FFET2725L also has bake, broil, keep-warm and self-cleaning modes in each oven but lacks the other notable features of the GE Profile. The Maytag CWE5800AC is the most basic of the bunch with just bake, broil and delay-start modes.
While each of these double wall ovens performs well at basic baking and broiling tasks, we chose to list the GE Profile PT925 as a best-reviewed product because it performs more functions, takes up less space and can still accommodate large items and quantities.
