Abstract
A Patio Heater Double Dome Infrared Heat Reflector/Converter is disclosed. The patio heater dome attachment is attachable to a conventional patio heater so that the dome attachment covers the heater's heat shield, while maintaining an air gap therebetween. There are preferably standoff ridges or other features built into the dome attachment to maintain this air gap and to prevent air from flowing freely between the heat shield and the dome attachment. The dome attachment embodies a very low heat load so that very little heat conduction occurs between the heat shield and the dome attachment, such that more of the heater's energy is reflected towards the usage area. Finally, the perimeter edge of the dome attachment extends downwardly at least until it is essentially horizontally planar with the perimeter edge of the patio heater heat shield.
