Radiant tube space heating appliance (FIG.,) has radiation ducting,with one or more inline burners,in a branch or branches,upstream of common tailpipe,. An exhuast fan,in the tailpipe draws heated gases thought the ducting. A power operated control damper,in the tailpipe is actuated in response to sensing of the gas temperature in the tailpipe to reduce the induced flow therein when the temperature is below a certain level to counteract the increased volume throughput of the adjacent fan at lower temperature so that performance burners, e.g. on start up, is not adversely affected.

Space heating appliances

A space heating appliance includes a radiant duct which, when heated, emits radiant heat for heating an area adjacent the duct. An insulated cowling shrouds the side of the duct away from the area to be heated in spaced relation to the duct. The cowling has a heat-emissive surface which when heated emits radiant heat toward the space to be heated. Between the duct and cowling in closely spaced proximity to the duct is an insulated heat shield which traps and redirects heat back to the duct in order to maintain the duct at a higher temperature and concentrate the emission of heat in the direction of the area to be heated.
