A gas-fired infrared heating device is described comprising: a burner plenum; an air-gas mixer means for introducing a combustible air/gas mixture into the plenum at a pressure P1 which is greater than ambient pressure, the mixer means comprising first means for controlling gas flow, second means for providing air flow at above ambient pressure and third means for controlling air flow into the mixer means; an enclosed but remote vented combustion chamber in which a back pressure P2 prevails, where P1 is greater than P2; a thick, ceramic burner tile having a sufficient thickness to produce both a pressure and a temperature gradient, forming a sealed boundary between the plenum and the combustion chamber and having opposite faces thereof addressing the chamber and plenum respectively. The tile forms therein small diameter parallel channels extending between the faces and possessing a sufficient thickness to produce both pressure and temperature gradients between the faces thereof; the first and third means being set such that the difference between P1 and P2 results in ignition and stoichiometric combustion of the air/gas mixture flowing from the plenum to the chamber via the channels substantially at the face of the tile which addresses the chamber; whereby heating the tile to infrared emitting temperature occurs.
