Space heater

Forced convection heaters utilize a device like a fan to generate air flow and spread heat at a fast pace.

Thermal radiation is a process by which objects at a high temperature emit heat in the form of electromagnetic waves.

Halogen heaters have tungsten filaments in sealed quartz envelopes, mounted in front of a metal reflector in a plastic case.

They operate at a higher temperature than nichrome-wire heaters but not as high as incandescent light bulbs, radiating primarily in the infrared spectrum.

They convert up to 86 percent of their input power to radiant energy, losing the remainder to conductive and convective heat.

Like infrared models, they lack a fan, but circulate heat according to a room's air patterns, which is why it may take longer for a user to discern a difference in temperature.

Roughly 6,000 hospital emergency department visits annually in the US are caused by space heaters, mainly from burns.
