Abstract
Water flow heater with a first heater element ( ) for supplying a fixed power, a second, controllable heater element ( ), a temperature sensor ( ) for measuring the temperature of heated water, and a control unit ( ) for controlling the heat supply from the second heater element ( ) in dependence on a temperature detected by the temperature sensor ( ). A water flowrate lying within a predetermined range is safeguarded in that a pump ( ) is provided for generating a water flow through a channel ( ), and the control unit is designed so as to activate the heater elements ( ) in dependence on activation of the pump ( ). As a result, the first heater element ( ) of fixed power can have a comparatively high power rating without the risk of water being too strongly heated thereby.
