Leisure cookers are available in gas, electric and dual fuel.
Dual fuel means that the hob burners are gas but the ovens are electric. Gas burners are very responsive and on some models there is a wok burner. Electric ovens means that you benefit from larger usable spaces, faster heating times, and a more even heat distribution.
Gas cookers have both a gas hob and a gas oven but require an electric mains supply to power the timer and ignition.
Electric cookers have electric ovens and ceramic hobs. Ceramic hobs are often considered easier to clean because of the one piece surface, but they can also be used as an extended countertop space when not turned on. Electric ovens offer faster heating times and even heat distribution thanks to fans.
