Heating performance - Ovens
Gas ovens of the past had a reputation for uneven oven temperature. The advent of fan assistance in gas ovens has changed that. The fan circulates the air in the oven and distributes the heat very evenly throughout the oven cavity. Having a fan in a gas oven allows for cooking on more than one shelf at a time - no hot spots.
Gas ovens have instant heat up use electronic ignition and do not require a pilot light. The can also run without the electricity connected.
Electric ovens provide a lot of control in how the heat is applied to the oven. While they don’t quite have the fast heat up time of gas, they heat and cool down quite quickly. Fan forced is the most popular function and while there is a slight bias left to right in temperature distribution, they are efficient and fast. Multifunction electric ovens allow a combination of heat from the top and the bottom of the oven. The elements can operate in a combination or individually, with or without fan assistance.
Heating performance - Cooktops
Gas burners produce instant heat, providing cooks with greater control over temperature. If natural gas is available it is generally considered to be the best option. Electric hotplates have improved and now heat up and cool down much better than in the past. There are ceramic and induction options that are more efficient than they used to be and they are good to use. They require a higher amperage circuit to cater for the high electrical loads but many modern homes are wired with this already taken into consideration.
