Superfast ovens roast and broil in a fraction of the time it takes with the old-fashioned variety. These ovens are covered in more depth below. The first thing you need to decide when shopping for a more mundane wall oven is whether you want an electric or gas model. In an existing kitchen, this is usually determined by what kind of oven you're replacing.
Experts say electric ovens heat more evenly, but gas ovens heat up and cool down faster.
Self-cleaning cycles, with their high heat, seem to exacerbate the problem. That's why, all things considered, most people prefer electric wall ovens, and why most new developments are in the electric oven arena. This model offers a large interior capacity, is self cleaning, and lets you broil within the main oven cavity, which frees up room for a storage drawer. You don't have to worry about self-cleaning fumes, but you'll still be sticking your head into an oven full of harsh chemical cleaner. If you go electric, there are many more models to choose from.
