Surface temperature An infrared panel heater should have a surface temperate of at least 80-90degrees so that it can be effective. If the surface temperature is only 40-50degrees, it's probably not a real
Though we cannot see infrared light, we can still use it. For example, a TV remote control uses infrared light to change the channels. You can use a digital camera to detect its presence. Aim a remote at a smartphone camera and press a button; you may see a light on your camera screen.
Infrared heaters are also classified as electric heaters as they are also powered by electricity. This, however, is all they have in common. Most electric heaters work with convection and infrared heaters with radiant heat. Using real examples, we will show you how the various electric heaters compare.
You might remember that infrared light isn't visible because it's beyond the spectrum we can see. That's the gist of an infrared heater: The heat is a product of light that is invisible to our eyes.
An infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm.
We understand why people look at infrared heating—it sounds energy efficient. But in reality, infrared heaters need to stay on longer to maintain warmth, and because they only heat what they directly touch, they often end up using more energy than expected.
The good news is that modern infrared heaters are very safe to use even when left unattended during the night, even while you are sleeping.
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.
Yes, infrared heating is generally considered safe for both residential and commercial use. Far-infrared (FIR) heaters emit a gentle heat that does not cause burns or other health risks.
But don't worry, infrared heaters are incredibly efficient. They're designed to keep a space warm while using as little electricity as possible. This makes them much cheaper to run than central heating, space heating, and air source heat pumps.
The main difference between infrared heating and space heating is that space heaters heat the air within a space, whereas infrared heaters heat objects, surfaces and people directly rather than the air.
Actually, they are both infrared heaters, except quartz heaters emit higher temperatures with resistance wire inside a quartz tube. A quartz heater can reach the temperature for which it is designed in less than a second; however, this time and temperature can be hard to control.
Infrared radiation doesn't have a colour because our eyes aren't evolved to see it.
Here are a few examples: Quartz Heat Lamps – Quartz heat lamps were developed by General Electric™ in the 1950s. They produce intense heat with a temperature above 2,732 °F (1,500 °C) and emit medium- to short-infrared waves. They heat surrounding bodies quickly.
More and more infrared-systems are also used for heating purposes in form of panels or foils, fixed to the walls or to the ceiling. Other applications are infrared cameras, night vision devices, infrared remote controls and infrared ports for computers.
To give you the quick answer, the majority of good infrared heating panels are designed with safety and efficiency in mind, allowing them to be left on throughout the day without major safety issues or costing you a small fortune.
The Infrared Principle
Infrared electric heaters emit thermal radiation through infrared waves. The infrared waves act as radiant heat, which will warm objects they come into contact with. In a similar way to how the sun works.
Let us put your mind at ease – infrared heaters are incredibly efficient. In fact, they're designed to use as little energy as possible while still keeping your space comfortable.
Oil filled radiator space heaters are some of the safest on the market. 1500W is all the juice an outlet will provide (Roughly 5,000 btus).
Near IR can be harmful to the eyes because it penetrates as far as the cornea (Voke, 1999). Uncontrolled, frequent, or long-term exposure to Near Infrared can also cause thermal burns and ageing effects such as “Bakers Arms” or “Glassblowers Face” (Cho & others, 2009).
