Do infra-red heaters heat the air?
Yes. Infra-red heaters first heat objects such as the floor, machinery, people, etc. Through various methods of heat transfer (radiation, re-radiation, conduction and convection) the air is heated secondarily as it passes over the warm concrete. Therefore, the heaters can be controlled by air temperature sensing thermostats. This method of heating is very effective in hard to heat areas such as high ceiling or high air exchange areas.
