A poultry brooder (10) having a ceramic radiant element (12) with protrusions (14) and protrusion connectors (16) forming spiral channels (18) to lengthen the path of flowing gases from closed center (34) to the edge of the radiant and to impede the gaseous flow by turbulence. An insulator (26) reduces heat loss through the rear surface (42) of the ceramic radiant and an adjustable temperature sensing element support bracket (32) allows selection of a variety of temperature sensing positions.
