Abstract

The unit (10) for heating liquid or gaseous media takes the form of a plane area element (22) which is provided with at least one insulated and sealed resistance heating element (30), and is chemically stable with respect to the medium being heated. The area element further possesses specified high-voltage insulation and limiting leakage current values, as well as a preferred thermal conductivity range.
