Whirlpool. The Whirlpool Gold freestanding double range fits into the same space as a traditional range but offers separate chambers for baking two dishes at different temperatures, simultaneously. The maker says the upper oven uses 50% less energy than a standard full-size oven and preheats in half the time. The double oven has a 6.3-cubic-foot capacity and features a Sabbath mode, and a Precise Clean cycle, which automatically determines cleaning time based on the number of times the oven has been used. Choose from white, black, or stainless steel finishes. 800.253.3977. www.insideadvantage.com.
