CONDUCTION is direct heat flow through matter such as the conduct of heat from the hot surface of a stove to a cooking pot. (Down heat flow 7%)
CONVECTION is the transport of heat within a gas or liquid caused by the actual flow of the material itself, such as heat traveling upward with the natural upward movement of air. (Down heat flow 7%)
RADIATION is the transmission of electromagnetic rays through space. These rays have no temperature, only energy. Every material or object with a temperature above absolute zero emits these rays in all directions, in a straight line, until they are deflected or absorbed. (Down heat flow 93%)
OF THE TOTAL HEAT THAT ENTERS YOUR HOME, THE HIGHEST PERCENTAGE IS BY RADIATION-NOT CONDUCTION OR CONVECTION.
