Abstract: An infrared radiation radiating system has a plurality of hollow infrared radiator casings mounted on and projecting forwardly or downwardly from a support. Each casing has a front portion in which a ceramic radiating element is mounted, and a tubular rear portion extending back from the front portion and being connected to the support. Thermally insulating material fills all or part of the front and rear portions of the casings as well as the space between the front portions and the support.
