Different ovens use different heating methods, but most rely on heating elements or gas burners to cook food. The rack position and selected settings determine whether a dish is browned, crisped, or gently baked. When choosing an oven, compare the capacity of single and double wall ovens to find the best fit for your kitchen.
A conventional electric oven cooks food using metal heating elements powered by electrical current. The lower element usually provides baking heat, while the upper element can broil. These ovens often produce drier heat than gas ovens, which can help crisp and brown food.
Gas ovens use burners powered by propane or natural gas. These burners create flames on the stovetop and inside the oven cavity, supporting baking, roasting, broiling, and other cooking methods. Because the flame is easy to adjust, gas ovens often preheat faster than conventional electric ovens.
Some convection ovens have an additional heating element at the back and a built-in fan. The fan circulates hot air evenly through the oven cavity and around food on multiple racks, helping food cook faster and more evenly. Convection is available on some gas and electric models, but the two oven types still differ in how they generate heat.
A steam oven heats water and directs steam into the oven cavity to cook food. It may operate in steam-only or combination steam-and-convection modes. Some ovens also offer a steam-cleaning feature, which uses steam to soften residue on the interior walls; this is not the same as steam cooking.
Induction heating usually refers to the cooktop, not the oven cavity. Beneath the surface of an induction cooktop is a copper coil that uses electromagnetic energy. When induction-compatible cookware is placed on the surface, the cookware heats up and cooks the food. The oven portion of an induction range typically uses electric heating or electric convection.
An oven broiler is a heating element or burner that provides intense, direct heat—usually from above. Like a grill, it creates high temperatures that can quickly brown, char, or caramelize food. Broiling is useful for adding flavor and texture, but food needs to be watched closely.
Electric oven: Electrical current heats the bake and broil elements.
Gas oven: A gas burner, usually at the bottom, produces heat.
Convection oven: A fan and often a rear heating element circulate hot air.
Steam oven: Water is heated to produce steam.
Induction cooktop: Electromagnetic energy heats compatible cookware, not the oven cavity.
If capacity and kitchen space are important, compare single and double wall ovens. Heating methods, convection, steam, and broiling features vary by model, so check the specific oven’s use and care guide for details.
