Considerations must also be made for moving objects around the infra-red heater and materials that have lower temperature ratings, such as plastics. Clearance to combustibles is defined as the minimum distance that must be maintained between the radiant tube heater surface and the combustible item. Safety considerations A critical safety factor to consider before installing an infra-red heating system is clearances to combustibles. This is easily done by vacuuming the surfaces of the unit occasionally or blowing it off with an air-compressor hose. Periodic dusting of the reflectors is beneficial not only for safety, but for the overall efficiency of the heater. This is recommended when dust or contamination that is present inside the building. Very little maintenance is required especially when bringing in outside air for combustion. or higher is recommended depending on the application and the model. Infrared radiant heaters require higher clearances than forced air units. While they are easy to live with, care needs to be taken when laying out the system to maintain clearances to combustibles. Negatives of infrared There are a few important things to consider when using radiant heat. Heater placement can be in the middle of the shop or perhaps even in a “U” or “L” shaped configuration around a workstation where the heat is needed most. Low intensity heaters can be vented together to reduce the number of roof or wall penetrations.ĭesign is flexible. It is capable of being installed along a sidewall and the reflectors can be rotated to direct heat where it is most needed. Spot heat to certain areas where workers are few.ĭirectional.

This makes for a much cleaner and quieter environment. For example:Ĭan save up to 50% fuel savings over forced air units.ĭoes not blow dust and debris around like heaters that rely on blowers for heat distribution. Positives of infrared Radiant heaters offer several operational and design benefits not available with conventional heating units. This creates the most efficient and effective heating method under the diverse conditions present in commercial and industrial applications. When doors are opened, the slab loses very little of its heat, and when the doors close, this mass acts as a huge heat sink to warm the surrounding air. However, with infrared heat the floor acts as a reservoir. When the doors close, the system will have to reheat the air as if from a cold start up. With a forced air system, heat escapes as doors are opened. This method of heating, as opposed to filling a room with warm air, allows the source of heat to begin at the floor level and not the ceiling. These objects, in turn, re-radiate the heat to create a comfort zone at the floor level. This energy is absorbed by objects in its path, such as the floor, machinery and people. Low intensity heaters have an enclosed flame.flectors.
