Abstract
A flow heater is provided for water in a machine which produces hot water. The machine includes a water tube having an inflow end for receiving water and an outflow end for dispensing hot water, and a heating tube connected to the water tube in a heat conductive manner. The heating tube is divided over its extent into a plurality of regions of different heating outputs for, respectively, intensely heating the water to below the boiling point in a first zone of the water tube adjacent the inflow end, followed by a less intense heating of the water to attain the boiling point in a second zone of the water tube, followed by an intense heating of the water until a vigorous formation of vapor bubbles occurs in a third zone of the water tube, and finally followed by a less intense heating of the water for reheating the water in a fourth zone of the water tube adjacent the outflow end.
