Where to buy the Kaiser KCT 7797 FI ElfEm hob
🏆 Review & price summary
The Kaiser KCT 7797 FI ElfEm induction hob is a 77cm built-in model with five induction zones, including two flexible 200 × 400mm areas and a central 210mm round zone. All five zones support Power Boost, while touch-and-slider controls, keep-warm cooking, automatic temperature control, residual-heat indicators, a child lock and Safety Guard automatic shut-off cover everyday use. The ivory bevelled ceramic-glass finish is its defining design feature. It is a strong fit for larger, design-led kitchens, but buyers must allow for the 740 × 490mm cut-out, a 7.8kW electrical load and separate ventilation.
✓ Key strengths
- ✓ Five induction zones with Power Boost across all five
- ✓ Two flexible 200 × 400mm cooking areas accommodate varied cookware positions
- ✓ Distinctive ivory bevelled ceramic-glass finish
- ✓ Full-touch controls with Power Slide adjustment and LED indication
- ✓ Keep-warm, automatic temperature control, Barbecue and Teppan Yaki functions
- ✓ Five separate residual-heat indicators, child lock and automatic safety shut-off
Worth considering
- The 7.8kW connected load is substantial, so the electrical supply and installation need checking rather than treating it as a simple like-for-like replacement
- The 77cm width and 740 × 490mm cut-out require more worktop space than a standard 60cm hob
- It requires induction-compatible cookware, unlike gas or conventional radiant hobs

Design and installation
The Kaiser KCT 7797 FI ElfEm induction hob combines a 77cm-wide frameless ceramic-glass surface with an ivory finish and bevelled edges. It is a visually distinctive choice for kitchens using matching light-coloured appliances.
The required cut-out measures 740 × 490mm, while the hob itself is 770 × 520mm. Its 6.2cm height and 7.8kW connected load mean the electrical supply and worktop dimensions should be checked before installation by a qualified professional.
Flexible cooking surface
Five induction zones are arranged as two flexible 200 × 400mm areas, two 200 × 200mm areas and one central 210mm round zone. The flexible areas are designed to accommodate cookware in different positions rather than restricting each pan to a fixed circular ring.
Power Boost is available across all five zones. The two flexible areas are particularly useful for larger or unusually shaped cookware, while the central round zone provides a conventional cooking position for standard pans.
Controls and cooking functions
Full-touch controls and a Power Slide give direct adjustment of heat levels, with LED indication for the selected setting. The hob also provides automatic temperature control, a timer or minute counter, keep-warm functionality and electronic precise simmer control.
Barbecue and Teppan Yaki programmes extend the cooking options beyond standard induction heating. Kaiser specifies an approximate 180°C setting for the long-duration Barbecue function and approximately 230°C for Teppan Yaki cooking.
Safety and everyday use
Five separate residual-heat indicators show which areas remain hot, with the indicator staying illuminated until the relevant temperature falls below approximately 60°C. Safety Guard automatic shut-off and an electronic child lock add useful protection during everyday use.
The smooth one-piece glass surface should be straightforward to wipe clean, although the touch controls need to be kept clear and dry for reliable operation. As with any induction hob, cookware must have a magnetically compatible base.
Verdict
The Kaiser KCT 7797 FI ElfEm induction hob is best suited to a design-led kitchen where a wider cooking surface, flexible zones and ivory styling matter as much as basic four-zone cooking. Its combination of five boost-enabled zones, flexible pan positioning and specialist cooking programmes gives it a strong feature set.
The main compromises are the larger worktop requirement, substantial electrical load and lack of integrated extraction. For buyers who already have suitable ventilation and want a distinctive five-zone induction hob, it is a capable and unusually styled option.
