Abstract: A modulating burner system includes a speed control responsive to inputs received from a thermostat. The speed control modulating a blower which provides combustion air and a vacuum proportional to the speed of the blower. The modulating burner system further includes a gas amplifying valve in communication with the vacuum via a vacuum conduit. The gas amplifying valve providing modulated combustion gas responsive to the vacuum; wherein modulated combustion air and gas communicated to a burner for continuously variable firing rates of 50 to 100% of the maximum firing rate. The modulating burner system further includes control circuit dampers for smoothing out vacuum spikes and fluctuations.

Abstract: The present invention is a radiant heat deflector assembly for radiating heat on a surface, wherein the assembly includes; a radiant heat source radiating direct emissions, and at least one radiant heat deflector spaced from the heat source. The heat source is so positioned and configured to include radiating direct emissions onto the deflector, the deflector being so positioned, configured and sized as to reflect radiant emissions onto a surface thereby heating the surface. Preferably the heat source adapted to radiate useful direct emissions upwardly towards the deflector and downwardly toward the surface or onto a second deflector such that both direct emissions and reflected emissions heat the surface. Preferably the heat source including an emitter for producing direct radiant emissions and the emitter producing useful direct emissions from both a top surface and a bottom surface of the emitter such that both direct emissions and reflected emissions reach the surface.
