All of our electric patio heaters are infrared. In fact the best patio heaters use short wave infrared. This produces warmth similiar to the heat we get from the sun. We also supply gas patio heaters.
Infrared radiation, or infrared light, is a type of radiant energy. It is invisible to the human eye but that we can feel as heat. Two of the biggest sources of infrared heat that we feel are the sun and fire.
German-born, British astronomer William Herschel discovered infrared light in 1800. In his experiment he observed an increase in temperature from blue to red light. He also noticed an even warmer temperature measurement just beyond the red end of the visible spectrum. Infrared heaters use this spectrum to deliver efficient heat.v Infrared heaters heat the person and not the air in the same way as the sun does.
