However, radiant energy is one of the forms whose particles can move within a vacuum quite efficiently. Radiant energy is important in a lot of fields, including telecommunications (especially over long distances and through wireless networks), heating technology, radiometry, and lighting.

Just as sunlight warms you, it warms the surface of the Earth as well. Energy from the sun is shown on the left where you see that part of the radiant energy from the sun passes through the atmosphere, is absorbed, and warms the Earth’s surface.

The sun generates energy from a process called nuclear fusion. About 30 percent of the radiant energy that reaches the Earth is reflected back into space. About half of the radiant energy is absorbed by land and oceans. The rest is absorbed by the atmosphere and clouds in the greenhouse effect.

Radiant is more commonly, and mistakenly, called static electricity. Recently, scientists have been investigating using this energy as a renewable energy; it could be a source of “free energy.” It is not that absurd of an idea. Static is created by the collection of excess charge on a surface. …

Infrared Heaters Generate Sun-Like Heat Infrared heat does not have a high frequency like ultraviolet rays and X-rays, which are known to cause cancer. The infrared heat generated by these heaters does not warm the air in the room and since air is not heated, the humidity of the room remains intact.

ANSWER: Electric radiant heaters are energy efficient and produce very comfortable heat. Since the surface temperature of these heaters is only about 150 degrees, they are very safe. To install one, you just hang it on the wall and plug the cord into a standard wall electrical outlet.

The most energy efficient heater really depends on the heater’s use. For intermittent heating, radiant heaters are much more energy efficient. They require little time or energy to achieve target temperatures. Achieving heat with a convection heater, on the other hand, is slower and more energy intensive.

Due to fire and safety concerns, portable heaters should not be left unattended. After use, they should be turned off and unplugged from the wall. Wall-mounted electric heaters have numerous safety features that make them both safe and reliable and can safely be left unattended.

Infrared heaters are also actually “healthier” than other heaters since they do not reduce humidity or oxygen content in the room. Other heaters can dry out your sinuses and skin, as well as cause static electricity. The infrared heat will even promote healthier blood circulation.

The cheapest portable electric heaters are oil-filled radiators (around 21p an hour) or halogen heaters (17p an hour). The cheapest fixed electric heater to run is a storage heater – which will only set you back around 13p an hour1.

They typically use less electricity and provide for more instant heat. They take longer to warm a room, but they provide a lot of heat and they are quiet. Good for heating a cold room all the time. Ceramic Fan blown heaters use fans to spread the warm air.
