High temperature radiant heating systems heat the room or space by radiant energy. The Sun, in fact, is the simplest example.  It exhibits high temperature radiant heating becuase the sun itself releases radiant energy. For example, people tend to feel comfortable when receiving sunlight during the winter time.

 

There are several examples of efficient heat sources: gas, fuel and electricity. And there are also three components in the radiant heating system, including the heating element, heat source and a reflector. As Figure RH1 shows that the most common high temperature radiant heating systems are usually installed on the ceiling of the structure. The radiant heat will be released above the people occupying the room. Reflectors help the radiant energy disperse in different directions. This process is the key point to this type of heating, to warm up the whole surface quickly. Furthermore, according to the different colors showing in the picture, the top part of the room is much warmer than the bottom part.  This is because warm air has a lower density and will float over the colder air in the space. In the winter, the radiant heaing  system will be more comfortable compared to a conventional heating system. In turn, a high temperature radiant heating system functions in the same way that the sun does, but on a much smaller and safer scale.  

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Radiant heating is especially benefical in buildings that have a large air volume or with a high infiltration load, such as waterhouses, air hangars, and other high bay facilities. These instances will be explained further in the typical uses, numeric parameters and limitations sections.
