No need to pre-heat. The B15E52S3GB single cooker from Neff looks really stylish in black, and it comes with some brilliant technology. CircoTherm speeds up cooking times by sucking in the hot air from the oven, heating it up and then pushing the air back into the cavity through carefully placed ducts in the back wall. You’ll need little or no pre-heating, plus tastes won’t be transferred. CeramiClean liners, another Neff trademark, absorb and burn grease inside the oven – leaving you with little cleaning to do.
