How Infrared Radiant Heaters Work
The two types of IR heaters are:
- tube [or low intensity] heaters
- high intensity [or luminous] heaters.
High intensity heaters
They consist of:
- a mixing chamber
- ceramic tiles
- a reflector around the burner
Pre-mixed air and gas are burned at the surface of the ceramic tile. The combustion heats up the tiles which then emit infrared radiant heat.
The gas-air-mixture is ignited at the surface by an electrode. The tube is heated by the flame and emits infrared radiant heat.
The flue gas of the radiant tube is vented to the outside. The combustion air can be taken from the inside of the building or from the outside.
Two-stage heating, is available for tube heaters.
Comfort at lower temperatures
The temperature experienced by people is the average of the air temperature and the radiant temperature.
