An infrared heater for use in an agricultural setting, particular for use in poultry houses, is provided that includes a burner assembly supported by an opposing pair of generally T-shaped end plates. The heater further includes a pair of emitter assemblies having a parabolic configuration that are each supported by an elongated emitter support. The emitter assemblies surround an inner core member assembly that in part define burn chambers. The heater includes a pair of end deflector members that together with the parabolic inner surfaces of the emitter assemblies direct infrared heat outwardly and downwardly in a wide and generally quadrilaterally shaped heat footprint.

A radiant tube heater with a burner assembly, a radiant tube assembly and a combustion air pre-heater, wherein the burner assembly comprises: a burner fuel nozzle; a plenum chamber and a pre-mixer chamber; the plenum chamber having a combustion air inlet; wherein in use: combustion air flows from said plenum chamber through an orifice to said pre-mixer where said air is mixed with burner fuel entering said pre-mixer through said nozzle prior to being combusted at a burner head; said pre-mixer being at least partly located within said radiant tube assembly; and where in use at least part of the combustion air supplied to said plenum is preheated in said air pre-heater using residual sensible heat of the hot combustion gas products of the heater.

A radiant heating apparatus having a tube, a partial enclosure device and a heating wing. The heating wing has a wing proximal end that connects to the partial enclosure device's exterior surface. The heating wing also has a wing distal end that obliquely extends outwardly in relation to the partial enclosure device and toward a first direction. The heating wing, except at the wing proximal end, and the partial enclosure device's exterior surface are spaced apart so the heating wing re-directs second direction heat energy in the first direction.

An improved radiant heater and combustion chamber for use with radiant heating are described. The combustion chamber is made up of two different materials in different regions, an insulating portion and a conductive portion. Heat transfer is maximized through the conductive portion, whose shape can be altered to modify the radiant energy being emitted. The improved radiant heater radiates substantial amounts of heat in useful directions over large distances without the use of reflectors.
