Abstract
A heating element is described for a regenerative heat exchanger that is constructed as a profiled steel sheet. The aim of the invention is to produce a heating element that is resistant to acids, has anti-soiling properties and, however, has a good thermal output. To these ends, the heating element is provided with an enameling, and a fluoroplastic coating is applied to the enameled surface.
