The invention relates to a heatable rotor blade (1) of a wind power installation (100) comprising a heating device (33) for heating the rotor blade (1), arranged in the the area of the rotor blade surface. In the past it has been difficult to target the heating performance along the length of the rotor blade. According to the present invention the heating device (33) has electrically conductive heating wires (2), and the heating wires (2) run in a sinusoidal, wave-like and/or zigzag-shaped way, with an amplitude, defining a sinusoidal amplitude, wave height or respectively spike height, and a wavelength defining a period length, wavelength or respectively a distance between spikes, wherein the amplitude and/or wavelength varies along the heating wires (2) in order to be able to adjust the specific areal heating performance of the heating device (33) for each section of blade.
