Abstract
The embodiment relates to a heating device having a plurality of electrical heating elements (1; 1a, 1b, 1c, 1d) composed of a cylindrical hollow body (2), electrical heating resistors being formed on the jacket of said hollow body and connection ports (3a, 3b; 3a1, 3b1, 3a2, 3b2, 3a3, 3b3, 3a4, 3b4) for the inflow and outflow of a fluid being arranged on the end faces of said hollow body. The heating elements (1; 1a, 1b, 1c, 1d) are arranged parallel to one another. Each connection port (3a1, 3b1, 3a2, 3b2, 3a3, 3b3, 3a4, 3b4) of a heating element (1a, 1b, 1c, 1d) is connected to a connection port (3a1, 3b1, 3a2, 3b2, 3a3, 3b3, 3a4, 3b4) of another heating element (1a, 1b, 1c, 1d) in such a way that the heating elements (1a, 1b, 1c, 1d) are connected in series in respect of fluid throughflow with a first connection port as a total inflow connection port (3a1) and a second connection port as a total outflow connection port (3a4).
