1. A wind turbine comprising:

  • a nacelle;

    at least one component mounted in said nacelle;

    a first temperature sensor for detecting a temperature of said component;

    a second temperature sensor for detecting a temperature outside of said nacelle;

    a heater associated with said component in order to heat said component;

    a heater controller operatively connected to said heater;

    said first and second temperature sensors being connected to said heater controller for applying first and second input quantities thereto so as to activate said heater when the detected temperature of said component lies below a predetermined switch-on value for said heater;

    said switch-on value for said heater depends in at least one predetermined temperature interval on the outside temperature detected by said second temperature sensor; and

    ,within said at least one predetermined temperature interval, said switch-on value at a first value of said outside temperature is greater than said switch-on value at a second value of said outside temperature when said second value of said outside temperature is greater than said first value of said outside temperature.
