How does a radiant panel heating work?

Radiant panel heating works by emitting infrared radiant energy that travels through the air largely unabsorbed until it strikes a solid object — a wall, piece of furniture, or floor. Approximately 85% of that radiant energy is absorbed by the object, raising its surface temperature directly. The warmed objects then radiate heat into the room and transfer some heat to the surrounding air by convection. This differs from forced-air heating, which heats air directly and relies on air circulation to warm the room.
