Gas fryers are cheaper to operate and are hot the moment you turn them on. They contain burners either encased in tubes running through the shortening or on the lower, outside sides of the fry pot. Gas fryers use natural or propane gas and may include filtration systems underneath for draining.

Electric fryers are more energy efficient. They heat the oil by immersing elements into the oil. Electric fryers sustain additional safety measures and are very precise in temperature control. Due to their low wattage, the life of heating elements and cooking oil is extended for a longer period of time.

Both gas and electric fryers consume energy while upholding the frying medium at the desired cooking temperature.
