Abstract

A portable heating unit has a heating chamber which is disposed within a housing so substantially all of the exterior thereof is displaced inwardly from that housing to define an air space. Air passing through that air space absorbs heat from the exterior of that heating chamber and also absorbs, and carries away, heat radiated from that exterior. That heating chamber is secured to that housing by mountings of small cross sections, which limit the amount of heat that can be conducted from that heating chamber to that housing. In addition, a baffle is interposed between the heating element and housing of the portable unit to reduce the amount of heat passing to that housing. A flame interceptor on the inner surface of the top of the heating chamber will largely intercept any flame which could develop as the wick of the combustion element was raised; and a guard is provided for the front of the heating chamber to minimize the risk of anyone contacting that heating chamber and also to keep the heating element from contacting the floor in the event the portable heating unit were to be tilted over onto its face.
