4D hot air ensures uniform circulation, enabling the Bosch HBG632BS1 to bake at 4 levels at the same time. The other types of heating, such as the infra-grill circulation or upper and lower heating, also ensure that your food is prepared just right in the 71 liters of available oven space. Choose a temperature between 30 and 300 °C. The Bosch quickly and automatically pre-heats, so your dish can be prepared as quickly as possible. A child safety lock and the maximum oven door temperature of 40 °C make the Bosch HBG632BS1 extra safe to use.
