How Do Portable Infrared Heaters Work?
So just how do these wonders of man kind work? An infrared heater is a unit which has a higher temperature then bodies of substance around it. It transfers its energy to things that have lower temperature by electromagnetic radiation. It depends on the temperature of the body that is emitting the energy as to what the wavelength of the infrared radiation will be. It can range from 780 nm to 1nm. Amazingly enough, there does not need to be a medium or contact between the two items for the energy to transfer. There is a classification of the infrared heaters for the wavelength bands where the emission of energy is concerned. 780 nm to 1400 nm is the range for the short or near infrared. These are named bright, as the emitters actually emit a glare that is visible to people. 1400 nm to 3000 nm is considered medium infrared and dark emitters or far infrared is for everything that is over 3000 nm.
