When we purchased this 800 series slide-in range we were introduced to precision heating control.  All five range top burners provide even heat at a continuous range of heat flow.  Simple boiling water comes to an even, rolling state on all burners.  Several temperature check measurements in several areas of the oven returned the selected temperature within the accuracy of an oven thermometer (250 to 400 F, +- 1 F).  Confidence in heat control leads to successful cooking, just what we expected from BOSCH.  We are very happy with our new BOSCH range.
