There is disclosed a furnace which is particularly suitable for domestic use, having means to generate infra-red radiation in a sealed combustion chamber to thereby rapidly heat the same and in turn impart that heat to air circulated therearound, and ultimately directed to the area to be heated, the combustion arrangement including a fibrous pervious burner member to and through which an air/gas mixture under pressure is directed and caused to burn over the surface thereof to effect the infra-red heat generation, the same effecting greatly improved heating efficiency, reduction in air pollution and a decreased demand for fuel to provide for heating of given area.

A radiant burner suitable for use in a heating apparatus, comprising a hollow fibrous porous matrix having a closed end and an open end, means including a plate closing the open end of the matrix, an inlet for a combustible gas-air mixture extending through the plate into the open end of the matrix, structure defining a cooling air chamber adjacent said plate and matrix and having peripheral cooling air outlet means adjacent the open end of the matrix, said matrix having a peripheral marginal edge near its open end exposed to cooling air flowing from said chamber through said outlet means, the peripheral marginal edge being saturated with a sealing material to make such peripheral marginal portion gas-impermeable.
