RADIANT HEATERS

Radiant heating is a technology for heating indoor and outdoor areas. Heating by radiant energy is observed everyday, the warmth of the sunshine being probably the most commonly observed example. Radiant heating as a technology is typically more narrowly defined. It is the method of intentionally using mostly the principles of radiant heat to transfer radiant energyfrom an emitting heat source to an object. Designs with radiant heating is seen as replacement for conventional convection heating. But also as a way of supplying confined outdoor heating.
