With its brushed metal fascia and white display featuring blue indicator lights, the Siemens HB13MB521B double oven really is the epitome of cool contemporary styling.
The large fan assisted 71 litre capacity main oven features 2 functions and includes 2 wire shelves on a choice of 5 levels and an enamel interior.
Siemens call their fan-only function ‘3D hot air cooking’. It’s ideal for all types of foods, cooking on up to 3 levels at the same time. Great for baking and roasting, ideal for larger joints. The second main oven function, a defrost setting, ensures slow and thorough defrosting of frozen foods.
In the secondary top oven the recessed grill cavity offers 35 litres of oven space for conventional cooking. There’s a full surface and centre surface variable grill, 2 shelf levels and bright interior lighting. The ActiveKlean rear and roof panels in this compartment burn off food residues leaving you to just wipe the sides and floor clean.
There’s bright interior lighting, 2x integral cooling fans and full width glass inner doors, which are double glazed to maintain an A energy efficiency rating in the main oven. With child safety lock, retractable controls, LED clock and automatic programmer.
