An Oven, Toaster, Grill (OTG) is a smaller version of a traditional oven. It uses heated coils to reheat, grill, barbeque, keep food warm or bake. All OTGs have the option to switch on one or both the coils based on what you want to cook. A multifunction built-in oven has multiple heating elements and a choice of heating methods, giving you more choice over how your food is cooked. Additionally, it is a faster method of heating or cooking.
