A coffee or tea maker has a freshwater receptacle which is connected with a continuous flow heater by a freshwater intake. Heated water leaves the continuous flow heater through a riser. The freshwater intake and the riser are coupled by a conduit in which cold freshwater and heated water admix and in which a thermostat switch is disposed. The latter controls the energization of the heater as a function of the temperature changes of the water mixture in the conduit. An additional heating means arranged in heat exchange relationship with the thermostat switch maintains the heater in a deenergized state after completion of the brewing process. An adjustable throttle valve may be provided for regulating the admission of fresh water into the conduit.
