ABSTRACT:
A heating apparatus including a housing defining a volume of air therein having an inlet and an outlet aperture. The heating apparatus also includes a heat generator having an elongate tubular metal sheath extending between an inner end and an outer end, a resistive wire within the sheath, and a substantially nonconducting material for electrically isolating the sheath relative to the resistive wire. The heat generator includes a terminal portion at the inner end and a heating portion extending between the terminal portion and the outer end of the sheath. The terminal portion is adapted for connection to a source of electrical power. Also, the heating portion of the heat generator is positioned in the housing to heat the volume of air. The heating apparatus also includes one or more insulators for electrically isolating the sheath relative to the housing.
