However, despite their name, radiators actually transfer most of their heat to a room by convection, not radiation. Normally radiant heaters must be at least red hot before they are effective.

Radiation is the transfer of heat energy from a region of high temperature to a region of low temperature by infrared radiation. Unlike conduction and convection, radiation takes place without the ...
