In use, water 64 is poured into the container 38 of the ultrasonic water vapour generator and the simulated coals 48 are arranged on the latticework 47 to simulate a bed of fuel as illustrated. The electrical power is then switched on, which activates the ultrasonic transducer 36, the lamp unit 42 and the fan heater 52. Activation of the ultrasonic transducer 36 within the water induces the formation and rapid cavitation of bubbles within the water in a known manner, which results in the formation of clouds of water vapour 66 having the appearance of white smoke. The clouds of water vapour pass upwardly and are deflected by the shroud 50 on the undersurface of the latticework 47, whereafter they pass around and between the simulated coals 48 located above. The clouds of water vapour 66 are drawn upwardly by the air current induced by the fan heater 52 and are discharged through the louvred outlet 62 in the front wall of the casing. The clouds of water vapour 66 are guided towards the fan chamber by a planar inner rear wall 68, extending parallel to the rear wal114 of the casing 10, and an inclined flap 70 extending downwardly and forwardly from the undersurface of the inner lower wall 58 of the fan chamber 54 and forming a cowling.
