Abstract

A heating pipe including a substantially tubular, electrically insulative inner element configured to allow flow of a liquid therethrough. An electric heating element in the form of a substantially flat ribbon of overheated amorphous metallic alloy is wound in a substantially helical pattern around the inner element. The helical pattern defines adjacent, electrically insulated windings. The inner element electrically insulates the heating element from liquid in the inner element. An electrically insulative outer element is provided for electrically and thermally insulating the heating element from the surrounding ambient environment.
