Abstract of the Disclosure Improved gas-fired radiant heater has porous re- fractory panel mounted by its edges on a support to define a gaseous combustion mixture plenum from which the mixture flows through the panel to burn at its outer face, and a conduit for non-combustible gas extends along the margin of the panel and discharges the non-combustible gas through the panel all along its margin to keep the combustion mixture from escaping through the panel edges where burning can damage the panel and to keep the panel support relatively cool. No further sealing of the panel margin is needed, but the sealing is effected with less of non-combustible gas if the panel edges are compressed so as to reduce their thickness about 10%. One or more of the margins of a rectangular panel can be arranged as a depending flange with its mounting at least partially recessed 90 that two or more panels can be juxtaposed at such margins to form an effect- ively continuous radiating surface of relatively large size. The air seal construction also makes such heaters very practical for firing house heating furnaces.
