ABSTRACT:
A coffee-maker is provided which comprises a first supply voltage terminal (10) and a second supply voltage terminal (11), a heating element (12), a first switching element (13), and a second switching element (14), which heating element (12), first switching element (13) and second switching element (14) are serially coupled between the first supply voltage terminal (10) and the second supply voltage terminal (11), the first switching element (13) being adapted to set the heating element (12) to a first keep-warm temperature and the second switching element (14) being adapted to set the heating element (12) to a second keep-warm temperature. For an improved control to set the heating element (12) to the first and the second keep-warm temperature, the second switching element (14) is adapted to set the heating element (12) to the second keep-warm temperature depending upon a time needed to establish the first keep-warm temperature.
