What is far infrared?
How long have we known about infrared?
Infrared radiation was discovered in 1800 by Sir Frederick William Herschel. Herschel, born in Hanover, Germany. It was Herschel who found that light passed through a glass prism would spread into a rainbow of colours. Most intriguingly, he found a curious reading when the thermometer bulb was placed just beyond the red portion of the visible spectrum. He had discovered thermal radiation, which has come to be known as infrared.
How do infrared heating units work?
When rays from the sun hit an object they warm it so in the same way, when radiation from an infrared heater hits an object (wall, ceiling, floor, door, ornament etc), it usually warms it. It is in fact either absorbed or reflected but infrared waves continue to radiate through a room until all their energy is absorbed and all objects have warmed up.Think of an infrared ray as a bouncy ball – you will know that if you drop a bouncy ball, it gradually bounces lower and lower until it stops.
This is because each time it hits a surface, a little of its energy is absorbed by that surface. The absorption of infrared radiation is very similar – the infrared waves jump around until their energy is absorbed throughout the room.
Infrared waves first hit the top layer of stone or brickwork and most of this energy reflects back into the room. Only a sixth of the energy is lost by absorption into the masonry approximately.
How does it effect us?
Infrared has always been around us and heats us and objects in our environment directly obviating the need for inefficient air heating systems, such as domestic central heating. Natures naturally occurring infrared rays warm the skin, the heat is then passed by the blood circulation around the body.
Infrared radiant heat cause a beautiful, clean, green and health giving comfortable warmth. Whilst heating us in the natural and cost effective way the rays are also heating the objects that surround us and even the walls of the room we occupy.
