Preferred by many chefs due to its speed and additional control, a gas oven operates on natural gas with a naked flame on the hob.
Electricity heats an electric oven. It takes more time to heat up, resulting in less initial control of the cooking temperature. However, there is no naked flame or the danger of any potential gas leaks.
A dual-fuel oven is a combination of an electric oven and a gas hob. Many of the ovens are a popular choice, including an LPG conversion kit that enables the use of gas bottles.
