Abstract
A device is provided for heating a liquid in a holder, having a heater element (31) designed to be placed in said holder and to be immersed in liquid in said holder, a temperature sensor (65) for measuring the temperature of the liquid in the holder and coupled to a control unit (41) for the thermostatic control of power supply to the heater element (31), a thermal safety cut-out (60) for interrupting the power supply to the heater element in response to heating-up of the heater element to above a given temperature, which safety cut-out (60) is in thermally conductive contact with the heater element (31), and a carrier (50) which is thermally coupled by means of a thermal coupling to a portion of said heater element which is immersed in the liquid in said holder in the operational state, the temperature sensor (65) of the thermostat being situated on said carrier (50) at a distance from said thermal coupling.
