What is Radiant Heating?

Radiant heating, Infrared Radiant heating, electromagnetic oscillation is the transmittance of heat energy from a hot object to a cold one, very much like the sun warms the earth. Heat energy is emitted from a hot element such as a gas-fired radiant tube or a luminous gas fired radiant plaque, produces infrared energy which travels in straight lines travelling through the air without heating it, and only turns into heat when striking a solid object such as a floor, wall or people stood under it. These objects become warmer than the air around them and in turn, give off convective air currents warming the air as a secondary event. Radiant infrared energy warms object and people in its beam and does not directly heat the air such as a warm air heater appliance would.   

The internal air temperature for radiant heated buildings will generally be lower than that for a conventionally warm air heated building but achieve the same high level of body comfort by having two third radiant one third air temperature and controlled by a black body sensor.

One of the key advantages of radiant heating systems is that it produces a still atmosphere which can be controlled in temperature zones, unoccupied or lower temperature zones can be switched off, much like switching off lights where it is not required. Radiant overhead panels are mostly used in higher roof type industrial production manufacturing, assembly plants, garage workshops, warehousing facilities, sports centres or for localised spot heating applications;

Pros of a Radiant Heater? 

  • Heats large spaces: Often in large buildings, only part of the available space actually needs to be heated. With radiant heating, you can easily have zones and only heat particular zones if and when required. Space heating, in contrast, requires all the air in the space to be heated in order to warm the area where the warmth is required.
  • Fast warm-up times: Radiant heaters get to full heat output within a few minutes. It then starts transmitting infrared energy to the surfaces.
  • Directional heat: This means that heat is delivered to where is it’s needed, so instead of warm air rising to the roof, heat is projected directly to the occupied areas on the floor.
  • Outdoor heating: As long as the heaters are suited to the external environment and sized to the application then it will be a workable solution. Radiant heating can even be used for warming outside entertaining areas to spectators at sporting stadiums.
