What type of electric heater uses infrared technology to provide warmth?

Radiant electric heaters utilize infrared technology to provide warmth by emitting electromagnetic radiation that directly heats objects and people in the room, rather than warming the air itself. This type of heating is efficient for both residential and commercial applications, as it allows for immediate warmth upon operation. The infrared waves emitted from the heater travel through the air and are absorbed by surfaces, which then release heat into the surrounding space.

This method of heating contrasts with convection heaters, which rely on the circulation of air to distribute warmth. Resistance heaters create heat through the physical resistance of electrical current passing through a conductor, which may or may not involve infrared technology. Panel heaters typically work more like convection heaters but can include radiant components as well. However, when specifically discussing the use of infrared technology, radiant electric heaters are the most appropriate answer.
