The invention relates to a device for heating preform bodies or flat or preformed semi-finished products from thermoplastic material (), comprising at least one base body (), on the surface of which at least a first layer or coating is formed, which comprises at least one electric heating resistor in the form of a flat, geometrically arranged conductor loop. The base body also has contact elements, by which the at least one heating resistor can be connected to a power source, wherein, as a result of the geometrically arranged conductor loop(s), a defined temperature profile can be generated, which can be transmitted contactlessly to the preform body or the semi-finished product by an outer contact layer formed on the first layer or coating, by contact the surface of a preform body or semi-finished product and/or by using convection or thermal radiation. During a transmission of the defined temperature profile, the preform body or the semi-finished product is arranged at a distance to the contact layer(s).
