<p>A continuous flow heater for water has a number of heating elements (R1, ..., R6) in the flow path (10, 20) which are arranged in such a manner that the water to be heated passes them in sequence. The temperatures (T1) of the inflowing water upstream of a resistor (R1) and the temperature (T2) of the water after passing this resistor are measured. From the two measured temperature values and the output of the resistor (R1), the output required by the following resistors (R2, ..., R6) which is necessary to heat the water to the desired target temperature (TS) can be calculated. <IMAGE></p> |
