The Siemens EA645GN17 iQ300 built-in cooktop impresses with its high performance and easy-to-clean glass ceramic surface. The EA645GN17 features four HighSpeed cooking zones, including a large dual-circuit zone and an additional switchable roasting zone. Since the diameter of the cooking zones can be selected to match the size of the pots, the dual-circuit and roasting cooking zones allow for flexible and energy-efficient cooking and frying. In terms of safety, the EA645GN17 includes a residual heat indicator that shows whether and which of the cooking zones are still hot.
