Abstract: A wind turbine has a nacelle wherein a component is equipped with a first temperature sensor for detecting a temperature of the component, a second temperature sensor for detecting an outside temperature inside or outside the nacelle, a heater associated with a component to heat the latter, and a heater controller. The detected temperature of the component and the detected outside temperature are provided as input signals to the heater controller which activates the heater for heating when the detected temperature of the component is below a predetermined switch-on value for the heater. The switch-on value for the heater is, in at least one predetermined temperature interval, dependent on the detected outside temperature. The switch-on value for a first outside temperature is greater than the switch-on value for a second outside temperature in the temperature interval when the second outside temperature is greater than the first outside temperature.
