Abstract: In order to further improve a method and a device for rehabilitating a pipe section, wherein the rehabilitation device has at least one tube-shaped inliner for sealing damage to the pipe section and a heating element, in such a way that the rehabilitation may be carried out more easily, safer, and more economically, it is proposed to design the heating element as a tube-shaped and electric heating element and to arrange it essentially across an entire length of the inliner arranged within the pipe section, and to cure the inliner essentially along the entire length in one step by means of the tube-shaped electric heating element.
