Most smoothtop ranges have four surface elements in three sizes: one or two medium-power elements (about 1,500 to 1,800 watts), a small element (about 1,200 watts), and one or two large ones (about 2,500 watts or more). Some have a warming element in the center section
-Smoothtops are sleeker and make it easier to wipe up spills because there are no electric coils or gas burners protruding above the surface.
-Induction cooktops take the cake for quick heating and energy efficiency.
-Pans for induction cooking must be able to attract a magnet to work.

The capacity of a burner is measured in British thermal units (Btu) per hour. Most gas ranges have four surface burners in three sizes: one or two medium-power burners (about 9,000 Btu), a small burner (about 5,000 Btu), and one or two large ones (about 15,000 Btu or more). Some have a fifth burner instead of a center section. Gas-on-glass models that mount gas burners above a smooth ceramic surface are an option.
-Gas burners can accommodate a variety of pot types and sizes.
-Gas ranges are available in sizes ranging from 20Ó to 60Ó, some with two ovens.
-Duel fuel ranges combine a gas cooktop with an electric oven for the best of both methods.
