ABSTRACT:
An electric air or gas heater includes a plurality of equal diameter elongated linear serpentine resistive wire heating elements circularly arranged in parallel about a common axis and disposed within a cylindrical chamber having separable air or gas entrance and exit sections at its opposite ends. Each heating element is disposed in a close-fitting ceramic or quartz tube. The tubes are supported by discs at the opposite ends of the chamber which block air or gas flow outside the cross-sectional area of the tubes. Each heating element has a ceramic cylinder extending through the center thereof through which a wire for electrically connecting adjacent pairs of heating elements extends.
