ABSTRACT:
An electric air stream heater adapted to operate directly on 120 volts with a wattage output of less than 500 watts without the need for any special control module, comprising, a cylindrical heating assembly having at least two spaced apart, parallel electrically connected lengths of crimped metallic foil provided with electrical power connections and secured to an insulating backing and rolled around an insulating core. Ceramic pins and a thermostatic control element which extend radially through the heating unit provide respectively, support means to prevent sagging of the heating elements in use and a means for detecting heat build-up across a large cross sectional area of the heater while creating a minimum of air flow resistance.
