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.

Heat transfer mechanisms are introduced. Heat conduction, convection and radiation are studied in this order. Techniques for analysing heat transfer problems are then covered. Two applications, heat ...

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 ...
