![]() The constant of proportionality σ, called the Stefan–Boltzmann constant derives from other known constants of nature. Specifically, the Stefan–Boltzmann law states that the total energy radiated per unit surface area of a black body across all wavelengths per unit time (also known as the black-body radiant exitance or emissive power),, is directly proportional to the fourth power of the black body's thermodynamic temperature T: The Stefan–Boltzmann law describes the power radiated from a black body in terms of its temperature. Now the technical science stuff on the how's and why's of Radiant Infrared Energy. When using radaint tube heaters over forced air heaters you can expect to save 30%-50% in your energy Bills! In general vacuum pressure systems are more efficent then Power pressure systems The radiant energy produced is then directed downward by the reflectors positioned above the radiant tubes. Radiant tube heaters operate by vacuum (negative) or power (positive) pressure. You can find a representative by clicking here or if you are looking for specifications for radiant heating tubes click here for Omega II radiant tube heater specifications or click here for Reflect-O-Ray tube heater specifications. Step three: Systems that take advantage of this principle are the OMEGA II and REFLECT-O-RAY Radiant infrared heating systems. Step two: Taking this to the next step simulating the suns radaint energy using an uncontrolled radaint tube heaters. ![]() Step one: Radiant Infrared Heat has its origins dating back to the begining of time. This all translates into better comfort, more efficient heating, and a lower cost of heating. Additional heating benefits are provided by the other masses with in a building tables, inventory, cars, ect… This method of heating keeps the heat where you need it down by the floor. The heating of the air within a building when using radiant tube heater is primarily done by the largest mass or heat sink in a building, the floor. The radiant energy that is radiated from the radiant tube heater is absorbed by floor and objects within a room without physical contact with the heat source. Radiant tube heaters deliver the heat to the ground level verses heating the surrounding air. Using a Radiant Tube Heater takes advantage of this principle, heating like the sun. To keep a house comfortable, you must replace the lost Btus with new ones each hour.Radiant Infrared energy is the oldest form of heating used to provide heating comfort. Each house has a distince Btu heat loss per hour. The Btu heat loss of your house is a function of its size, insulation, window and door openinngs, compass direction it faces, etc. Keep in mind that your house may be much different than other houses in your neighborhood. A good way to do that is to figure out what it costs to generate 10,000 Btus using each type of fuel. Always compare fuel prices based on Btu of heat output. For example, you may live in an area where electricity is insanely cheap and the cost of propane is outrageous, while I may live in an area where fuel oil is the best buy per Btu. One type of fuel may cost much more per Btu of heat produced than another. ![]() Even with this in mind it's a very hard question to answer because there are many types of radiant heating systems and each one might have a different fuel source. The cost to operate a radiant heating system that uses a central boiler and one or more recirculating pumps can be minimal. It's possible to have a radiant heating system totally invisible with all the piping hidden in floors or ceilings. People choose them as that's almost always the cheaper alternative. You don't have to install wall or baseboard radiators.
