The ability of a burner is calculated in British thermal units (Btu) per hour. Almost all gas ranges have 4 surface area burners in 3 sizes: one or two medium-power burners (about 9,000 Btu), a small burner (about 5,000 Btu.) and one or two big ones (about 15,000 Btu or more). Several have a 5th burner rather than a middle area. Gas-on-glass models that mount gas burners above a smooth ceramic surface are an option.

Positives:
An skilled chief cook might discover it simpler to assess heat by the look of the gas flare, and gas burners can support a selection of pot types and sizes. Smoothtop and coil components are likely to maintain temperature longer than gas burners when you move from a high to a low setting.

Downsides:
In general, electric ranges provide faster high cooktop heating, though performance is mode specific.
