Basics working principle Best known radiant heating system is the sun Infrared heat of the sun can be sent for 1,000s of miles without loss of energy Radiant effect can be easily felt when leaving shade and then moving into the sun The air temperature will be the same but everybody feels the radiant effect Human beings do not feel the air temperature, they feel the average of the radiant effect/temperature and the air temperature Every object emits infrared heat, the hotter the object the more heat is being emitted Radiant effect heats up walls, floor and objects in the room high comfort 11/25/2008 7
