In radiant electric heating, how is heat primarily transferred to the space?

In radiant electric heating, heat is primarily transferred to the space through direct radiation from heated surfaces. This method of heating relies on the principle that warm surfaces emit infrared radiation, which directly increases the temperature of objects and people in the room without first heating the air. This makes radiant heating particularly efficient, as it targets the occupants and furnishings, increasing comfort levels without relying solely on air movement or temperature.

The effectiveness of this approach can be observed in how it minimizes heat loss, as it does not depend on the circulation of warm air, making it advantageous in maintaining consistent and comfortable temperatures. This contrasts with convection heating, where the air is heated and circulated, which does not have the same level of direct impact on surrounding surfaces and bodies. Thus, the essence of radiant electric heating lies in the direct transfer of heat via radiation, making it uniquely suited for certain applications.
