The ultimate source of radiated heat is the sun, which generates vast amounts of infrared heat through gas consumption. This infrared heat passes directly through space, but it warms the surface of the earth and is, in fact, the energy source that makes life possible on earth. On a sunny day in winter the sun’s warmth comforts us even though the air around us is below comfort temperature.

While the sun is a terrific source of infrared heat, it also delivers damaging UV rays, which leads some people to falsely conclude that the same problem applies to infrared heaters. See similar questions...

A thermostat shuts off the infrared heaters when the desired air temperature is reached. Better results are achieved with a thermostat that measures both the air and the mean radiant temperature to provide true comfort temperature. This special feature is offered exclusively by the Schwank TruTemp setback thermostat, that also has an automatic temperature set-back when it senses that the building is unoccupied.

By conduction through solid bodies, such as through a windowpane in your heated house to the (cold) outside. The rate of heat transfer by conduction is proportional to the temperature difference and the conductivity of the material through which the heat travels. Through convection by warming air and moving the warmed air to a cooler area. See similar questions...

John Jones and I designed his heating source around the three most important consumer benefits: economy, comfort, and safety. The final development of this infrared quartz heat source cannot be matched by any other heating system in the world. In the SunTwin system, electricity is used to generate infrared light which, in turn, creates a very safe heat. Infrared is the safest form of heat because it does not create carbon monoxide or harmful radiation. See similar questions...

There is a lot of misunderstanding about how infrared heat warms a broiler chicken or a broiler house. Infrared heat is the kind of heat that comes from a glowing brooder. It is the same kind of heat that we experience when we stand in front of a fire on a cold winter day. Even though the air temperature between our bodies and the fire is cold we still receive warmth from the glow of the fire. See similar questions...

Gas-fired infrared heaters are mounted overhead to direct infrared energy to the floor and the objects, including people, at the occupancy level of the building. The infrared energy is absorbed by the floor and objects at floor level - all of which become warm and in turn heat the air in the building. Moreover, the floor and objects continue to release heat to the air, even after cold air is introduced or the infrared heaters are turned off. See similar questions...

People feel good when warmed by radiant heat – like the warm feeling on a gray day when the sun breaks through the clouds. Panels are lightweight, one inch thick and can be installed either inconspicuously or as an architectural feature. Each room can be controlled by its own thermostat, heating only the space in which heat is desired, just like electric lighting. Enerjoy panels operate on the same principle as the way the sun heats the earth, naturally and comfortably. See similar questions...

Much like Bluetooth Infrared (IR) wireless data transmission is also employed in short-range communication among personal digital assistants (PDAs), mobile phones, FAPtops, PCs and printers. Its main differentiation from Bluetooth is that IR is a line sight communications technology, meaning that the two device IR transceivers must have plain line of sight in order to communicate.

Yes and no. Outdoor models are designed for well ventilated places. Well ventilated does not mean you have a bit of a draft under a crack in the door. In a garage with a window or garage door open, yes you can safely use any of the 12-IR -> 24-IR range of heaters The DESA range of infra-red heaters is the way to go for indoor infra-red heat. These units are designed for indoor use and have safety mechanisms built in to protect you. See similar questions...

Infrared rays are located just past the red portion of the visible light spectrum. While some experts believe that infrared light can be harmful in certain situations (such as being near large bodies of water or at high altitudes), most feel that the sun's infrared rays do not pose a danger to the eyes.

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. See similar questions...

Infrared radiation is one of the many types of 'light' that comprise the electromagnetic spectrum . Infrared light is characterized by wavelengths that are longer than visible light (400-700 nanometers, or 0.4-0.7 micrometers; also denoted as microns). Astronomers generally divide the infrared portion of the electromagnetic spectrum into three regions: near-infrared (0.7-5 micrometers), mid-infrared (5-30 micrometers) and far infrared (30-1000 micrometers).

Infrared light from the sun is experienced on the earth in the form of heat. Quality sunglasses protect your eyes from the fatiguing and drying effects of infrared radiation. See similar questions...

No, in fact it may actually reduce it because of our unique Reflectflow system which re-directs warm air back in the room. See similar questions...
