A coffee maker for brewing coffee comprises a water reservoir, a heating chamber and a pump which pumps water from the reservoir through the heating chamber to a filter device. The heating chamber is provided with a temperature sensor which causes regulation of the power supply to the heating element (16) and also provides temperature information to a control device. The control device controls the operation of the pump so that the brewing process is automated, and the pump is operated only when the water at the outlet of the heating device (10) is at a suitable temperature. The heating device (10) may be a low-mass instantaneous flow heater.
