Abstract
A gas fired infrared radiant heating system of improved thermal output. The present invention solves problems associated with prior art designs by providing a single gas delivery system for delivering combustible gas to two or more burner assemblies. The invention consists of a burner housing (10) with two or more burner assemblies (18), each of which can be connected to a typical radiant tube heat exchanger assembly (12). The burner housing contains a single gas delivery system including a valve (14), a single control circuit module (30), a single blower proving switch (50), and a single manifold (16) which will distribute the gas to the multiple radiant tube heat exchanger assemblies (12). In addition, in positive pressure configurations, the burner housing will also have a single air fan (38), whereas in negative pressure configurations of the heating system one or more exhaust fans may be utilized. The foregoing design will provide a higher thermal output without the heat distribution and installation cost problems of the currently available infrared heaters.
