  "textContent": "A method is provided for operating an electrical flow heater in a vehicle, in particular an electric vehicle, wherein the flow heater has multiple electrical heating circuits for electrically generating a respective heating power in a heating section through which a medium to be heated flows, and a power control of the respective heating power of the respective heating circuit is carried out by a control circuit by controlling a respective controllable electrical switch element of the respective heating circuit. A sum of the heating powers is adjusted to a total heating power. With the control circuit, a distribution of the total heating power into the heating powers of the heating circuits is carried out according to configuration data, wherein the configuration data is independent of a current temperature of the medium to be heated.",
