ABSTRACT:
A portable air heating system for use in all areas is disclosed. The portable air heating system provides a stream heated air for use in heating the interior of a structure, in 360°, multidirection, or a direction. Directional heating is accomplished through exhausts ports located all around the assembly. The heating system generally comprises an air transfer assembly for providing a flow of air through the system, an electrical heat emitting assembly, and a heat transfer housing for safely transferring the heat produced by the electrical heating assembly to the air flowing through the transfer assembly. Additionally, liquid filled bladders may be added to the heat emitting assembly to conserve and retain heat longer which will be said unit more energy efficient. The present heating system is also highly portable and simple to use, thereby providing an efficient mechanism for providing perform conditioning functions, such as air moving, heating, or cooling.
