Abstract
In order to reduce limescale formation on the continuous flow heater during operation of an apparatus for preparing freshly brewed hot beverages which has a hot water generator, which is embodied as a continuous flow heater, and a brewing apparatus, to which hot water from the hot water generator can be supplied, a controller for actuating the continuous flow heater is provided, which controller switches on the continuous flow heater for the purpose of drawing a pre-specified quantity of hot water and switches off said continuous flow heater shortly before the quantity of hot water is completely output, so that the temperature of the hot water at the output of the continuous flow heater is declining at the end of the drawing operation.
