Infrared waves and heat rays from gas radiant overhead tube heaters warm people and objects, just like the sun warms you on a cold winter day. This heat is carried by electromagnetic waves from the tube heater to people and surfaces but is not seen or felt until it has made contact. In addition to warming people, the surrounding surfaces are also warmed.
The tube heater’s fan burner generates a long laminar flame heating the tubes up to 650°C, allowing the tubes to emit infrared heat through a special alloy.
Tube heaters are also referred to as ‘dark heaters’ because they do not glow brightly like luminous heaters. In fact, tube heaters do not emit any light at all.
The heat felt by these heaters always sits above the actual air temperature. The lower air temperature also reduces the differences between inside and outside temperature, thus cutting down on the heat transmission losses at the same time.
