Zanussi ZGRW3226HL is a ceramic hob with four cooking zones, including a HiLight zone, that allows you to cook food quickly and efficiently. The hob has a residual heat indicator that lets you know when the cooking zones are still hot, even after they have been turned off. This helps prevent burns and ensures that you don't waste energy by leaving the hob on longer than necessary. The hob also has a number of safety features, such as an automatic shut-off function that turns off the hob if it detects that there is no pan on the cooking zone.
