Radiant heating involves the direct transfer of heat to objects through infrared waves. Convective heating involves heating the air surrounding objects within a space.
RADIANT HEATING Radiant heating involves the direct transfer of heat to objects and people through infrared waves. Radiant heating heats the surfaces of the objects themselves, whilst convection heating heats the air in between the objects. Radiant heaters produce an even heat using minimal energy requirements because they do not require fans to distribute heat in the same way as convective heaters do. In large open indoor spaces, radiant heating is extremely efficient and effective as it provides targeted warmth to the people and objects below, and allows zoning of the heat. Radiant heat is the only viable option for heating outdoor spaces where there is considerable air movement.
CONVECTIVE HEATING Convective heating involves heating the air surrounding objects within a space. Utilising natural air movement, convection heating can be a quick and effective method for heating small enclosed, well insulated spaces such as bedrooms, living rooms, classrooms and offices. However, convective heating can be an impractical and inefficient means of heating large open spaces with high ceilings and poor insulation such as halls, libraries, shops, large classrooms, restaurants, open plan offices and studios etc., as the heated air rises to the ceiling or is lost through poor insulation, rather than remain in the area that people occupy.
