Infrared rays are electromagnetic waves. It is important to note that  all living bodies are emitting infrared rays without exception, not just heaters. The biggest source of infrared light is the sun. They make up about 80 percent of all the sun's rays (besides them, the sun emits a lot of visible spectrum rays as well as the ultraviolet UV rays that burn our skin).

We do not see infrared rays, but we feel them as heat. Both the human body and any surface absorb radiated heat. When infrared light penetrates any solid surface, it is transformed from light energy into thermal energy. Therefore, the heated objects warms up first and then the indoor air warms up.

The infrared rays system makes possible to control the heat direction in much the same way as we do with light - the heat flow is directed only to the right areas. This is instantaneous heat only when it is need for it and only where it is needed - for example only during work time or then you are present at home. The heat is localized to the area where people are located - it does not disappear or dissipate in large indoor or outdoor areas. This system is easy to install where it is desired.
