What is radiant heat energy?
Radiant heat energy is the type of energy emitted from an underfloor heating system, and the easiest way to explain the principle is to compare it to the energy we get from the sun. The sun transmits radiant heat energy across vast distances through deep space vacuum, here on Earth this energy is partly absorbed and partly reflected by people, objects and the Earth itself The fact that radiant energy does not require a medium such as air to be effective, means that it does not necessarily heat the air it is passing through. For instance, if you are outside on a cold frosty morning as the sun rises over the horizon, you will instantly feel the heat from the sun, but the air temperature is unchanged.
