What does infrared do to water?
Infrared light could help split water into hydrogen and oxygen, despite the fact that infrared photons have less energy than is needed to drive the reaction.
Infrared panels can also heat objects in the room using this type of radiation. The infrared rays release heat onto the surface, regardless of the environmental temperature. Most objects absorb this radiant heat and slowly release it back.
The system uses pulses of electricity and infrared heat to keep energy use to a minimum and heat the objects and people in your home, rather than the air. The system requires no plumbing or complicated wiring; the panels are simply mounted on the internal walls of your home (facing the external walls) and plugged in.
Infrared radiation is strongly absorbed by water and by the atmosphere. Although invisible to the eye, infrared radiation can be detected as warmth by the skin. Nearly 50 percent of the Sun's radiant energy is emitted in the infrared region of the electromagnetic spectrum, with the rest primarily in the visible region.
Infra red light is severely attenuated in water, depending on the exact wavelength.
It will depend on the strength (intensity) of the infrared light being emitted and the sensitivity of the receiver or detector, but a range of 10 ft is well within the range of most TV remote controls for example.
When an object is not quite hot enough to radiate visible light, it will emit most of its energy in the infrared. For example, hot charcoal may not give off light but it does emit infrared radiation which we feel as heat. The warmer the object, the more infrared radiation it emits.

Infrared panel heating is energy efficient with proven savings as much as 50% compared to other conventional heating systems. Infrared panels are very easy to install, simply need to be mounted on the wall and plugged into a power socket.
There's also no need to preheat a room since these heaters work instantly. Some use only 300 watts of electricity and almost 100 percent of the heat created is transferred out, so you can get super efficient heating for a very low cost. The maintenance for infrared heaters is extremely minimal.
Is an infrared heater better than an electric heater?
An infrared heater is better than an electric heater in terms of energy efficiency. These heating units use 100% of the heat produced compared to 80-90% for electric heaters. Infrared heaters also offer various power source options, such as propane, natural gas, and electricity.
Summary: pros and cons of infrared heating panels.
|Don't take up much space||Can't fully replace a boiler|
|Simple to install|
|More efficient than central heating systems|
Atmospheric water vapour at ambient temperature and pressure gives rise to absorption in the far-infrared region of the spectrum, from about 200 cm−1 (50 μm) to longer wavelengths towards the microwave region. Vibrational transitions in which a molecule gains a quantum of vibrational energy.
Pure distilled water has been shown to be relatively transparent to ultraviolet radiation.
Water is a one-of-a-kind substance for many reasons. An obvious one is its unique ability to absorb heat. Water is able to absorb heat - without increasing much in temperature - better than many substances.
To trap infrared light, Jiang and colleagues turned to a unique material called black silicon, which is commonly incorporated into solar cells. Black silicon absorbs light because it consists of millions of microscopic needles (called nanowires) all pointing upward like a densely-packed forest.
It all comes down to the color: Why infrared prefers black to white. The heating process in plastics processing is much quicker for darker materials. The reason behind this is that black plastic absorbs infrared radiation better than white or transparent materials.
The transparency of glass to visible light makes it the most common way to let light into a building. But because glass is also transparent to near-infrared radiation -- windows also let in heat, giving rise to the well-known greenhouse effect.
Walls are generally thick enough—and insulated enough—to block any infrared radiation from the other side. If you point a thermal camera at a wall, it will detect heat from the wall , not what's behind it.
Red light occupies the “long end” of the visible spectrum with wavelengths of 630nm-700nm. Infrared light is invisible and is effective for use on the surface of the skin and penetration of about 1.5 inches into the body. Infrared sits right next to a red light on the electromagnetic spectrum at 800nm to 1millimeter.
Can some people see infrared?
Science textbooks say we can't see infrared light. Like X-rays and radio waves, infrared light waves are outside the visual spectrum. But an international team of researchers has found that under certain conditions, the retina can sense infrared light after all.
Because most heat generates light in the infrared, scientists often refer to infrared light as heat. This is a generalized term or a convention. Technically heat energy and light are different things, but heat energy can be measured by its EM radiation.
Infrared waves are associated with heat because they have enough energy to excite electrons, thereby lifting them to higher energy levels. This translates to rotational and vibrational energy, leading to the haphazard jiggling of molecules.
Near infrared light, with wavelengths between 700 – 1400 nm, generates the most heat but does not penetrate deep into human tissues.
Are Infrared rays safe for people? Far infrared heating is 100% safe and natural for our bodies, and our well-being, as the human body is designed to accept and emit infrared. The feeling of warmth from infrared is particularly comfortable. It is UV that is harmful, not infrared, and so there is no need to worry.
