Gas infrared radiant heaters generate radiant heat similar to the sun's rays. People, objects and surfaces are heated directly without heating up the ambient air: despite low ambient temperatures, a pleasant warmth is felt. The heat is directly available exactly where it is needed.
In practice, this means that the air temperature can be kept 3 to 5 Kelvin below the set temperature - with an optimum, comfortable feeling of warmth and energy savings at the same time.
Infrared heating systems can also be used to heat specific areas, e.g. workstations in production halls.
