energy is the frequency range on the electromagnetic spectrum that
falls immediately below visible red light. The body's tissues normally
produce infrared energy (which is why people can be seen on infrared
cameras) for warmth and tissue repair. Infrared energy can penetrate
the body more than an inch to provide heat deep in the body where it is
needed. Conventional heating systems only heat the air around the body.
Infrared is the energy behind the warmth we feel from the sun, even on
cold winter days.
wintertime, we feel we need to wear a sweater in order to be
comfortable in a room with an air temperature of 18C (70F) However, in
the summer time, we feel comfortable with short sleeve shirts and
shorts with the same air temperature. Why is this? It is because the
infrared waves heat the objects around us and this heat radiates and
warms our bodies. We’re warm on the inside.
waves are thermal. In other words, we experience this type of infrared
waves every day in the form of heat! The heat that we feel from
sunlight, a fire, a radiator or a warm sidewalk is infrared. The
temperature-sensitive nerve endings in our skin can detect the
difference between inside body temperature and outside skin temperature.
Infrared heat waves can be felt, but not smelt or seen. This is
implied by the name: The prefix "infra" from Latin, means "below", or
"beyond". So we are talking about electromagnetic waves, which are
“below-red” in the visible light spectrum. The Infrared band covers a
range of wavelengths between 780 and one million nanometres (1
millimetre). The human eye can not perceive these wavelengths. To help
explain this, a single human hair is about 70,000 nanometres thick.
Infrared waves are therefore invisible to us but we know that they are
there because we can feel it on our skin.
Our elements mainly emit low-impact, long-wave infrared-C waves, which penetrate and warm solids.
The difference is in the air
Unlike conventional heaters which just heat the air, Redwell heats
the walls. The walls store heat much longer than the air and release it
slowly back into the room. Thus, the walls remain dry and mould has no
chance to spread. Another advantage is that the air does not circulate
so less dust is picked up.
