Where to buy the Kaiser KCT 7797 FI RotEm hob
🏆 Review & price summary
The Kaiser KCT 7797 FI RotEm induction hob combines five induction zones with two flexible double fields, allowing more freedom over pan placement than a conventional fixed-ring layout. It also offers Power Boost, Power Slide touch control, keep-warm, individual timers, child lock and automatic shut-down.
✓ Key strengths
- ✓ Useful freedom over pan positioning
- ✓ Rapid heating, including up to 4.3kW on the largest field
- ✓ Power Slide touch control, keep-warm, timers and child lock cover the main everyday-use features
- ✓ Barbecue and Teppan Yaki modes add specialist cooking options
- ✓ Bevelled edges and is easy to wipe clean
Worth considering
- The 77cm width and 74cm cut-out mean it is not a direct replacement for a standard 60cm hob
- Its 7.8kW connected load requires more careful electrical planning than lower-powered hobs
- Only the left and right double fields are flexible; the central cooking area is a fixed 210mm circle
- The Barbecue and Teppan Yaki modes are restricted to their respective double fields rather than being available across the whole hob

Flexible cooking space
The Kaiser KCT 7797 FI RotEm induction hob provides five induction zones, including two flexible double fields that allow cookware to be positioned across rectangular heating areas. This is more adaptable than a conventional hob with only fixed circular rings, particularly when using larger pans or griddles.
The central zone remains a fixed 210mm circular area, while the flexible fields are arranged to the left and right. Power Boost is available across the five zones, with the largest double field reaching 4.3kW.
Controls and cooking functions
Touch controls and a Power Slide interface provide direct control over heat levels. The hob also includes a keep-warm function, individual timers or minute counters, electronic child lock, automatic safety shut-down and five separate residual-heat indicators.
The dedicated Barbecue mode operates at approximately 180°C, while Teppan Yaki mode heats cookware to approximately 230°C. These modes add genuine specialist functionality, although each is limited to its designated double field.
Installation and electrical requirements
At 77cm wide, the Kaiser KCT 7797 FI RotEm hob is larger than the common 60cm built-in format. It requires a 74cm-wide by 49cm-deep worktop cut-out, so it is best suited to a new kitchen installation or a carefully measured replacement project.
The 7.8kW total connected load is substantial for a domestic hob. Electrical connection should therefore be planned with a qualified installer rather than treated as a simple plug-in appliance replacement.
Design and everyday maintenance
The Bordeaux red glass surface with bevelled edges gives the Kaiser KCT 7797 FI RotEm hob a distinctive appearance and makes it suitable for coordinated statement kitchens. Its flat one-piece ceramic surface has no raised pan supports or burner caps to obstruct wiping.
The glass finish will show marks more readily than some patterned or darker surfaces, but the smooth layout remains straightforward to clean after spills.
