ABSTRACT:
The invention relates to a coffee maker assembly which has a heat exchanger having inlet and outlet pipes. Heat for the heat exchanger is supplied by an electrical heating element. In one embodiment a PTC resistor is in series with the heating element and thermal connections are provided between the resistor and other parts of the system. This allows thermal conditions to be sensed which alter the resistance of the PTC resistor to effect a temperature control by varying the magnitude of current supplied to the heating element. Another embodiment illustrates the heating element itself being formed by an annularly shaped PTC resistor.
