With its brushed metal fascia and white display featuring blue indicator lights, the Siemens HB55NB551B built-in double oven really is the epitome of cool contemporary styling. The main multifunction 67-litre capacity oven features 9 functions and includes 3 wire shelves on a choice of 5 levels. There's bright interior lighting, 2x integral cooling fans and full-width glass inner doors, which are triple glazed to maintain an A rating for energy efficiency. There's a fast heat-up function and intensive hot air setting, which uses heat from the top element to cook the perfect pizza, with no need to pre-heat the oven. Conventional cooking is also supported and the main cavity boasts a dual circuit grill for extra flexibility. A bottom heat only setting is perfect for finishing off pastry dishes such as quiche. A defrost setting ensures slow and thorough defrosting of frozen foods. Depending on which cooking function you choose, the oven will automatically suggest the temperature at which that function will produce the optimum results. Don't worry - this temperature can still be easily manually adjusted if required! With the residual heat indicator bars, the temperature of the oven is displayed even after the oven has been switched off, reducing in stages down to 60°C, so that food can be kept warm until you need it. Once all the bars have extinguished, the residual temperature will be under 60ºC. For meals with long cooking times, you can switch off the oven 5-10 minutes earlier thereby saving energy. In the secondary top oven, a conventional oven and grill cavity offers 35 litres of oven space. There's a full surface and centre surface variable grill, 2 shelf levels and bright interior lighting. The ecoClean® rear and roof panels in both ovens are four times more efficient than standard catalytic liners and will provide you with an excellent cleaning performance time after time. With child safety lock, retractable controls, LED clock and automatic programmer.
