A second element at the top of the oven may also supply some of the heat. A newer type of oven uses a fan to circulate heat. These ovens are called convection ovens. Convection ovens cook faster than conventional ovens, but may take a little time and practice to get accustomed to. Some cooking procedures may need changing.
Convection ovens distribute the heat all around the product with a fan system.
The oven capacity may be smaller. This feature will cost more. Continuous-clean ovens clean as they are used at normal temperatures. Certain abrasives or cleaners cannot be used on them. Additional occasional cleaning with a sponge and sudsy, hot water is needed.
