Where to buy the Kaiser KCT 7797 FI Em hob
🏆 Review & price summary
The Kaiser KCT 7797 FI Em induction hob combines five boosted zones with two flexible 20 x 40cm cooking areas, giving it more adaptable pan placement than a conventional four-zone hob. Individual timers, keep-warm, simmer control, Barbecue and Teppan Yaki modes make it versatile, while the wide built-in format and high electrical demand need careful installation planning.
✓ Key strengths
- ✓ Generous cooking capacity
- ✓ Two 20 x 40cm flexible areas accommodate larger or rectangular cookware
- ✓ Power Boost is available across all five zones, with up to 4.3kW on each flexible zone
- ✓ Individual timers, keep-warm and automatic simmer control improve cooking control
- ✓ Useful safety features
Worth considering
- The 77cm width and 74cm-wide cut-out require more worktop space than a standard 60cm hob
- The high connected load requires a suitable electrical installation and is not a simple plug-in replacement
- The touch controls need to be kept clean and unobstructed; the manual warns that contamination or objects over the sensors can affect operation
- The Teppan Yaki mode is designed for use with a special tray, so its usefulness depends on having suitable cookware

Kaiser’s own pages differ on two installation-related figures: the UK page lists a 7.8kW total load and 49cm niche depth, while the German page lists 7.4kW and 49.5cm. Check the supplied installation documentation before fitting.
Cooking flexibility
The Kaiser KCT 7797 FI Em induction hob provides five cooking zones, including two flexible 20 x 40cm areas. These rectangular zones allow cookware to be positioned across a larger area, making the hob more adaptable for griddles, roasting dishes and unusually shaped pans than a conventional four-zone layout.
All five zones have a Power Boost function. The two flexible zones are rated at 3.5kW, rising to 4.3kW with boost, while the central 21cm zone reaches 2.6kW with boost. This gives the hob strong rapid-heating capability for boiling and high-temperature cooking.
Controls and everyday use
Full-touch controls with a Power Slide interface provide direct adjustment of the cooking levels. Each zone has its own timer or minute counter, so several dishes can be managed independently rather than relying on one shared countdown.
Keep-warm, automatic simmer control and residual-heat indicators add useful day-to-day convenience. The manufacturer also includes dedicated Barbecue and Teppan Yaki modes, although the latter is intended for use with a special tray rather than ordinary cookware.
Design and installation
The Kaiser KCT 7797 FI Em induction hob has a black glass-ceramic surface with bevelled edges and a 77cm overall width. Its smooth one-piece surface should be straightforward to wipe clean, while the wider format gives more room between pans than a typical 60cm hob.
This is a built-in appliance with a stated 74cm-wide niche. Buyers should check the installation documentation carefully because Kaiser’s published pages differ slightly on the niche depth and total connected load. Electrical connection should be handled by a suitably qualified installer.
Safety and efficiency
Five separate residual-heat indicators remain active until the relevant zone falls below 60°C. A child lock and Safety Guard automatic shut-off provide further protection, while the induction surface heats the cookware rather than relying on a continuously hot exposed element.
The hob’s induction system offers quick temperature changes and a smooth surface that is easier to clean than a traditional solid-plate design. As with any induction hob, it requires compatible ferromagnetic cookware, and the touch sensors need to remain clean and unobstructed for reliable operation.
Research note: this BestBuysUK assessment is based on the manufacturer's published specifications and other reputable technical sources. Specifications and retailer availability can change, so verify critical details before purchase.
