    (54) Fluid flow control device


    (57) A space heater has an elongate combustion tune (12) and a burner device (52) for supplying a combustible mixture into an inlet (34) of the tube through which the mixture and combustion products are caused to flow by a fan (58). An air conduit means has a part (36) which receives the heated gas and distributes it for heating purposes and an air duct (44) which extends longitudinally of and adjacent the tube in heat flow communication with a first region of the tube. The tube is arranged so that it emits radiant heat from a radiation region circumferentially spaced from the first region.
