The oven is used for warming, roasting and baking. It works by surrounding the food with hot convection currents. The oven temperature is adjusted by a thermostat that varies the amount of heat surrounding the food to be cooked. The grading ranges from a simmer or economy setting of around 100◦C through to gas mark 9, which generates temperatures of around 245◦C. Most domestic ovens found in the UK work by natural convection currents. The burner located at the rear of the base creates a circulation of hot gases that eventually discharge from the rear of the oven by means of a flue. Owing to the relatively slow circulatory motion, temperature zones invariable develop in the oven, with the hottest region at the top. In another design of oven, the gas burner is located outside the food compartment and hot air is allowed to enter via various ports, so producing a more even spread of heat temperature throughout the oven. This design is often used with an additional fan to give improved efficiency.
