Abstract

The invention relates to an apparatus for heating a pipeline system, comprising at least two pipelines (1), along which in each case one electrical resistance heating element extends, wherein a potential close to the ground potential is set at each electrical resistance heating element at at least one end (3, 5), and the electrical resistance heating element is connected to a terminal of a DC source or to in each case one phase (7) of an n-phase AC source (9) at a position remote from this end (3, 5), where, when using an n-phase AC source (9), n is an integer equal to or greater than 2.
