A heating apparatus comprises a burner means 34 which produces visible flames 42, reflective means 28 positioned behind the flames 42 and partially reflective and partially transparent means 26 positioned in front of the flames 42. The reflective means behind the flames 42 may be curved in only one plane such that it is concave and has a constant cross section which lies on the surface of a circle. The partially reflective and partially transparent means 26 positioned in front of the flames 42 may be a planar glass sheet with the front surface of the sheet treated to reduce its reflectivity. The apparatus may further comprise a decorative bed 30a,30b,38, so arranged that the flames 42 from the burner 34 are produced without impinging on the decorative bed 30a,30b,38 and the combustion of fuel in unhindered by the decorative bed 30a,30b,38. A housing 14 of the apparatus may be provided with an exhaust aperture 36. There may be provided a means 46 for altering the colour of the flames produced by the burner means. |
