Never clean your oven again: the activeClean® self-cleaning system.

At the touch of a button all deposits from baking, roasting and grilling turn to ash at high temperatures – simply wipe off with a cloth.

100 % hot air, 30 % less energy consumed: hotAir Eco.

For everyone who likes to use hot air while saving energy: The Siemens innovation hotAir Eco not only stays as much as 30 % below the maximum allowable energy consumption to achieve an energy efficiency rating of A, but also provides perfect cooking and baking results. Whether you bake frozen pizza, cake or lasagna, hotAir Eco with special temperature control has been systematically optimised for energy-saving baking and roasting with hot air on one level.

Reach the required baking temperature sooner: fast pre-heating.

The optional fast pre-heating function heats the oven especially rapidly – without consuming more energy. For instance, the oven is pre-heated to a temperature of 175 °C in approx. 5 minutes (with 3D hotAir heating).
