Infrared Tube Heating Systems
Even though infrared tube heating has been around for decades, it’s still a relatively unknown concept in the HVAC industry. Infrared heat works similar to the sun, in that it gently warms people, floors, and objects. As a result, these objects retain and regenerate heat back into the space and not up to the ceiling or out the door like air heaters do. This translates into greater comfort and energy savings. Even the premiere HVAC trade association ASHRAE recognizes these facts and has recommended reducing heat losses by 15% – 20% when using infrared equipment.
How is this accomplished? Infrared heat is part of the electromagnetic spectrum. The wave length defined as infrared is the portion of the spectrum just beyond the visible red light. Infrared heating utilizes all methods of heat transfer:
The most important of these methods of heat transfer is radiation. Infrared heaters generate radiation which is the transfer of energy and wave form from a hot surface to a relatively cooler surface without any means of heat transfer such as air. It is a direct transfer of energy. The ability of an object to absorb infrared energy is also very important. Most materials within a building such as, concrete, metals and water are highly absorptive, therefore making it ideal for heating with infrared.
Conduction is the transfer of heat through a solid object. This allows the building to heat evenly by spreading the heat throughout objects and also warm the air through convective energy from these warmed objects. These concepts combined cause the heating dynamics of a building to be different. The heat loss to obtain equivalent comfort is less, therefore allowing the user of infrared heating to use less energy and install less heating capacity.
Infrared heating systems consist of a burner, heat exchanger tube and reflector. A flame is ignited, that flame is drawn down a highly emissive tube by a fan or pump, then a geometrically designed reflector directs heat down toward the floor.
- Easy to install
- Easy to maintain
- Easy to operate
Infrared heating is clean, quiet, and draft free, making it ideal for wide spaces like warehouses, manufacturing areas, transportation facilities, airplane hangars, and many more. Infrared heating is a win, win, win, for building owners, occupants and installers alike.
