What is Quartz Heating?
Quartz heating is a type of radiant heating, commonly referred to as short wave infrared heating. Radiant heating uses infrared waves to directly heat the surfaces of objects. All objects emit and absorb infrared heat, which is part of the electromagnetic spectrum with a frequency below visible light. Hotter objects will radiate more infrared heat. This is the basis of the technology for most infrared quartz heaters.
Infrared heat was discovered in the early 19th century by William Herschel, who named the invisible light as ‘infrared’ because he believed it was ‘below the red light,’ as ‘infra’ in Latin translates to ‘below.’ This meant that Herschel discovered a form of light (now known as ‘infrared’) beyond red light in the electromagnetic spectrum and it marked the first time in history that someone showed there were types of light that cannot be seen by the naked eye. The very first infrared heaters used what is known as ‘near infrared’ or ‘short wave infrared,’ which is closest to red in the light spectrum and able to contain large amounts of heat.
How Does Quartz Heating Work?
The principle of quartz heating (a type of radiant heating) is well-known and has been in use for many years. Electric infrared energy travels in straight lines from the heat source. This energy is directed into specific patterns by optically designed reflectors. Infrared, like light, travels outward from the heat source and diffuses over a distance.
Quartz heating works similar to the sun, travelling in parallel lines, even able to pass through the vacuum of space. This is why quartz heating is not affected by wind and able to directly heat people and objects. Quartz heaters are suitable for outdoor heating as well as indoor heating and due to their heat intensity, are also highly effective for space heating.
How Quartz Heaters Work
A quartz heater is a common type of infrared heater and the creation and subsequent release of heat from the heater is made by the heating element, enclosed in a quartz tube. The heating element produces infrared heat at the necessary wavelength to create the appropriate level of intensity to heat the specific material required. The purpose of the quartz tube is to protect the heating element and also to stop the escape of convection heat.
The principle of quartz heating works with the heating element becoming very hot and the quartz tube experiencing a sudden build up of heat. When the quartz tube reaches the appropriate temperature, the infrared heat is emitted out of the quartz tube. The wavelength of heat produced from this process has been acknowledged as ideal for the human body. The infrared heat is directly absorbed by the people and objects near the quartz heater and very little infrared heat is absorbed by the air, due to the infrared spectrum being almost completely outside the absorption spectrum of air.
