ABSTRACT OF THE DISCLOSURE A heating apparatus has a combustion portion for forming a flame for generating heat and light with an at least semi-transparent cylindrical tube surrounding an outer periphery of the combustion portion, and a cylin- drical net-like member disposed at the interior or exterior of the cylindrical tube at a location spaced from the flame and prevented from making contact with the flame, the net- like member being made of 2 to 30 mesh lath net, from which in use images of speckled patterns are visible coming from the mesh openings at front and rear sides of the combustion portion, which are apparently overlapped in a positionally shifted relation, an outer surface of the lath net being treated so as to provide a reflecting surface.
