They use a heated quartz element that emits a safe, clean wavelength of light that is only absorbed by solid objects, transferring heat directly to a person, table or floor rather than heating the air. For this reason, infrared heat can be distributed very evenly, and will not simply "blow away" in windy or drafty areas. These heaters are 93% efficient and a pleasing glow that will not affect the ambience of your outdoor space.
They are able to directionally project a comfortably diffused radiant heat deeply into outdoor spaces. The Platinum Smart-Heat utilizes glass-cermaic technology to manipulate infrared energy while achieving unparalleled wind resistance.
