Abstract
A radiant tube heater, primarily for agricultural buildings and preferably intended for poultry breeding buildings, includes a burner box or heat creator, which is an enclosure with pressurized and non-pressurized sides, a gas control valve and orifice assembly; ignition control and components, a burner assembly, and an air proving switch. Attached to the burner box is a heat distributor which includes a radiant heating tube unit. The radiant heating tube unit is comprised of an elongated two-section tube extending from the burner box, wherein the first tube has a round cross section and a cross section having a diameter less than the width of the second tube. The second tube is characterized by having a non-round or oblong, preferably oval cross section, wherein one set of opposing sides of the oblong tube are longer than the ends of the tube. A transition piece connects the first tube with the section tube. An open reflector is situated for reflecting the radiant heat to a desired location.
