Far-infrared radiant (FIR) heat is a form of naturally occurring energy that heats objects by direct light conversion (DLC). DLC warms only the object and does not raise the temperature of the surrounding free air. All life requires FIR heat from the sun. FIR heat is not ultraviolet radiation but a narrow band of energy within the 5.6 to 15 micron level. This type of energy travels only 2-3" deep into the body to increase circulation and nourish damaged tissue.

Of course, the Sun is our primary source of Infrared heat. Have you ever been outside on a partly cloudy spring day of about 50 degrees F. and felt quite comfortable until the sun was suddenly obscured by a cloud? Although the air temperature had not had time to drop, you felt chilled, as the cloud would not let the warming infrared rays through to reach you. Infrared light is an important energy force that promotes healing - a rising of the white blood cell count.

Infrared heat is light produced by the sun. This is the heat you feel penetrate your skin when you stand in the sun - and miss when you walk into the shade. Infrared energy is also given off as body heat. The human body can also absorb infrared heat. Infrared energy is measured in wavelengths as microns. The human body can best absorb infrared energy in the 3- to 50-micron range, with the best absorption occurring at 9.4 microns.

Far infrared is a vital source of “light” energy that you're probably not getting enough of. It’s part of the electromagnetic spectrum of sunlight that’s safe and extremely beneficial to your health. If you want the scientific explanation, then click here.

With radiant heat, the temperatures the floor temperatures tend to be stable and low. These are favorable conditions for wide pine floors. It is best to use material that has low humidity from the beginning. Probably not, if the building will be energy efficient. While heat will tend to rise, you are asking one floor to do the work of two and you may want to over design the first floor.

This is a concrete question more than a radiant heating question. All concrete applications must be structurally satisfactory. There is no important difference between concrete mixes from the heating standpoint.

Radiant heat is transmitted from a heat source via rays just like rays of sunlight. These rays pass through the air without heating it since only solid objects can absorb the heat they transmit. Dark colours absorb more radiant heat than lighter colours. This is why light coloured clothing is cooler than dark coloured clothing.

Is far infrared heat safe? Infrared heat is completely safe and all objects give off and receive infrared heat. In fact, it is so safe, hospitals use similar heaters to warm newborns. Infrared is a part of nature and essential for life. The human body gives off and receives infrared in the far infrared band. When a mother rubs a babies stomach to relieve pain, it is the infrared heat from her hand that is causing the healing effect.

Far Infrared Rays have nothing to do with either ultraviolet radiation (which gives you sunburn and damages your skin) or atomic radiation (the kind from a nuclear bomb.) Far Infrared Radiation is simply a form of energy that heats objects directly through a process called conversion, without having to heat the air in between. Our sun is the principal source of radiant energy that we enjoy daily (some more so than others).

Therapy, in medical term, means the act of remediation of a health problem, after the diagnosis. Far Infrared Therapy is a type of low energy therapy using light in the far infrared spectrum for the treatment of a health problem. Far Infrared Therapy is also sometimes abbreviated to FIR Therapy or Infrared Therapy for short. The light we see every day is actually a combination of many different types. All light is electro-magnetic waves. The wavelength of light determines its properties.

An Eichler radiant heat system that has copper pipes can be repaired and maintained indefinitely with a little periodic maintenance. However, if your radiant piping is made of steel, as was done in many mid-'50s Eichlers, it may not be repairable. In any case, be sure to recruit a qualified radiant heat specialist (and perhaps even a second opinion) to diagnose your situation and lay out your options. More information. Don't mess with it.

Can I receive constant infrared heat from my Clearlight Far Infrared Sauna? Infrared heat is most effective at lower temperatures as sweat oils secrete at lower temperatures and this sweat is different than water sweat. Your Clearlight Far Infrared sauna is designed to heat your body more so than to heat the cabin (about 80% of the heat heats your body and 20% of the heat heats the sauna cabin).

Infrared heaters warm the body in the same manner as natural sunlight. FIR heat therapy uses the wavelength of the visible and non-visible light spectrum of sunlight that heats the body normally. Traditional steam saunas raise the temperature of the air to a very high level within the chamber to warm the body. FIR saunas work differently. Instead of heating the air within the enclosure, FIR saunas emit a wavelength and heat the body directly.

It is a warm soothing heat that helps feet relax by warming the muscles and ligaments. It is especially helpful for feet that have been under hours of strain.

No, while it's true the sun's rays should be used judiciously, especially by fair-skinned people, the fact remains that infrared radiation is safe and promotes vital health. It is the harmful ultraviolet light that Sunscreen lotions block. There are many harmful rays given off by the sun but Far Infrared Rays are not among them. The energy is absolutely essential and beneficial for human beings and all living things in the world.
