A positive temperature coefficient (PTC) heater includes a housing, a fan mounted within the housing, a pair of positive temperature coefficient (PTC) heater assemblies disposed in the housing, and a plenum mounted in the housing. The housing includes a front portion and a rear portion connected together to define a front, a rear, a left side and a right side, the front and rear each having at least one opening. The fan is arranged to produce a flow of air from the rear of the housing to the front. The pair of positive temperature coefficient (PTC) heater assemblies are disposed in side by side relationship and angled relative to each other, each at an angle of approximately 7.5 degrees from normal, so as to produce a diverging column of heated air. The plenum mounted in the housing directs the air flow produced by the fan through each of the PTC heater assemblies.

1. A positive temperature coefficient (PTC) portable electric space heater comprising:a) a housing having a front and a rear, said rear having an opening and said front having a pair of openings at least one opening; b) a fan mounted within said housing for producing a flow of air into the housing from the opening in the rear and then out of the housing through the pair of openings at least one opening in the front; c) a pair of positive temperature coefficient (PTC) heater assemblies disposed inside said housing in front of said fan in side by side, end to end relationship and in front of said of fan, said pair of PTC heater assemblies being angled relative to each other such that air drawn in to the housing by the front fan passes through said PTC heater assemblies and emerges through the at least one front opening as a diverging column of heated air, each PTC heater assembly comprising a plurality of ceramic PTC pellets situated in a grid of conductive material dispersed over a large area for quickly heating a room; d) a contiguous heater assembly support means structure having a pair of mounting openings therein for mounting the heater assemblies in side by side, end to end divergently angled relationship within inside said housing for holding said PTC heater assemblies in place in said housing; ande) a grille in each opening in the front of said housing, each grille being aligned parallel with one of said PTC heater assemblies; and f e) a plenum provided mounted inside said housing positioned behind said PTC heater assemblies; g f) said plenum together with having an outer periphery coupled to said heater assembly support means structure for directing all of the air drawn into said housing from the opening in the rear by said fan into through said PTC heater assemblies to provide the diverging column of heated air.
