The invention relates to a method for determining an output temperature of a fluid after flowing through a PTC heater with a PTC heating element. In the method a current of the PTC heating element, a supply voltage of the PTC heating element and a duty cycle of the supply voltage are determined, and the output temperature of the fluid is calculated based on the current (I), the supply voltage and the duty cycle (PWM). The invention also relates to a PTC heater for carrying out the method.
