A method for controlling a temperature of a liquid in a liquid container filled with at least a first predetermined amount of the liquid using a heating device. The temperature of the liquid in the liquid container is measured and controlled by adjusting the heat output of the heating device. If the liquid container is filled with less than the first predetermined amount of liquid until the liquid container is filled with a second predetermined amount of the liquid, wherein the second predetermined amount of the liquid is equal to or greater than the first predetermined amount of the liquid, cool liquid is fed into the liquid container from a liquid reservoir, the heating device is permanently activated, and the temperature of the liquid in the partially filled liquid container is controlled.

A method for controlling a temperature of a liquid in a liquid container using a heating device, wherein the temperature of the liquid in the liquid container is measured by a temperature sensor and controlled by adjusting the heat output of the heating device if the liquid container is filled with at least a first predetermined amount of the liquid, wherein if the liquid container is filled with less than the first predetermined amount of liquid, a cool liquid is fed into the liquid container from a liquid reservoir through a metering valve controlled by a pulse-width modulated (PWM) signal until the liquid container is filled with a second predetermined amount of the liquid, wherein the second predetermined amount of the liquid is equal to or greater than the first predetermined amount of the liquid, wherein if the liquid container is filled with less than the first predetermined amount of the liquid and until the liquid container is filled to the second predetermined amount of the liquid, the heating device is constantly activated, and the temperature of the liquid in the partially filled liquid container is controlled by adjusting the cool liquid volume flow rate of the cool liquid fed into the liquid container by controlling the opening area of the metering valve with the PWM signal.
