Aside from the fact that electric deep fryers and gas deep fryers use different heat sources, the main differences between the two are:
Heating and recovery speed: Electric fryers use a heating element that’s immersed in the oil, so they heat the oil faster than an equivalent gas fryer. In contrast, gas fryers heat up the fry pot first, which then heats the oil, and so take longer to reach the desired temperature. For the same reasons, electric fryers recover faster, allowing operators to cook more items in quicker succession.
Capacity: Gas fryers typically have higher capacities than electric ones, so are more suitable for high-volume establishments.
Installation: Whereas gas fryers need to connected to a gas line by a qualified professional, electric fryers can simply be plugged into an electrical outlet, making them faster, easier and cheaper to install.
Control: Electric fryers usually allow for more user control. For example, they feature adjustable thermostats that allow you to set the temperature of your oil quickly and easily.
Ventilation: Electric and gas fryers both require an adequate ventilation system, but electric models don’t need a gas interlock system to be fitted and maintained.
Maintenance and repairs: Gas fryers are more complicated than electric ones and typically require more frequent maintenance, increasing the operating costs.
