Introducing FlameSelect® on Bosch cooktops, an entirely new and better way to cook with gas. 9 preset power levels let you easily adjust flame level for more precise, controlled heating. Whether you’re rapidly bringing water to an intense boil or delicately melting chocolate, the numbered flame levels deliver the exact temperature every time. There’s no more hot or cold spots, just precision heating for perfect results. Control knobs with an embedded red LED light line indicate if the burner is on or if there is residual heat. The OptiSim burner design is wider and thicker which diffuses heat evenly for better flame control when simmering delicate sauces. The low-profile cooking surface provides a timeless, streamlined look while keeping spills contained and makes clean-up easier than ever.
