Abstract
A hob includes at least one heating zone having several heating elements, a user interface for setting a heating capacity of the heating zone, and a control unit for operating the heating elements and for distributing the heating capacity among the heating elements according to a heating capacity distribution. In order to improve the efficiency of the hob, the control unit is configured to distribute the heating capacity among a larger number of heating elements when the heating capacity is below a threshold value than in the case, when the heating capacity is above the threshold value.
