Abstract
To determine the temperature of boiling water in an induction hob including induction heating coils which can be individually driven and which, in a common heating mode, form a cooking point for a cooking vessel containing water, the cooking vessel is positioned over at least two induction heating coils. The induction heating coils are operated in the heating mode to bring the water in the cooking vessel to boil and each induction heating coil heats that region of the cooking vessel base arranged above it. During the heating mode, the oscillation response at each induction heating coil is used to detect whether temperature of the region of the cooking vessel base above this induction heating coil increases. The induction heating coils are operated in the heating mode until one induction heating coil detects that the temperature gradient of the cooking vessel base above the induction heating coil has reached zero.
