What is the difference between top/bottom heat and circulating air in the oven?<end_of_turn>
<start_of_turn>model
Top and bottom heat or circulating air differ in how exactly the heating takes place. With top and bottom heat, there are heating elements (usually spiral-shaped) that are installed in the ceiling or bottom of the oven and transfer heat to the baking chamber. With circulating air, it is a fan at the back of the oven that conducts the heat into the oven.
Most baking recipes are based on top and bottom heat – and on the middle rack. However, baking with convection also has some advantages. On the one hand, the heat is distributed more evenly throughout the interior of the oven. That's why you can bake several trays on top of each other on several levels, for example if you're baking larger quantities.<end_of_turn><eos>
