  • Patent number: 11207844
    Abstract: Described is a heating device for thermally connecting a pipe, which has a first plastic material, to a bushing, which has a second plastic material, and which surrounds at least a section of the pipe, wherein an inductively heatable heating means is located between the pipe and the bushing and/or integrated in the pipe and/or the bushing. The heating device has a coil arrangement, which is excitable by a generator, and which has a first coil, which has at least one complete winding within a first cross-sectional area, and a second coil, which is electrically coupled to the first coil, and which has at least one complete winding within a second cross-sectional area. The first cross-sectional area is different from the second cross-sectional area. Furthermore, a heating system having such a heating device as well as a method for thermally connecting a pipe to a bushing are described.
