Why is Space-Ray more efficient than unit heaters?
The major difference between a gas-fired infrared heating system and a forced hot air heating system is the method used to create a comfortable temperature. Infrared heats the floor slab, the machinery and the people first and then the air by using all three methods of heat transfer: radiation, conduction and convection. The storage of the heat in the slab floor creates a low temperature emitter and a faster recovery time when large overhead doors are opened and closed. With a forced air system, the hot air rises to the ceiling and stratifies, gradually working its way down to thermostat level so that the floor slab never becomes warm enough to be comfortable. It literally acts as a heat sink, draining heat from the air and from personnel standing on the floor. The ceiling area of a high bay building using a forced air system can be easily 30° to 40° warmer than the floor area. In the same type building heated with an infrared system, the temperature is much more uniform and the loft o
