Infrared is the invisible transfer of radiant heat.
There are different wavelengths of Infrared. Short/Medium are more intense, Far (or Longwave) is less intense. It’s mostly the sun’s short and medium-wave infrared that reaches us here on earth, but when absorbed by the surface of the Earth, that heat is radiated back as longwave (far) infrared. So, the feeling of heat from a hot wall or beach is far infrared. This is completely natural and safe.
Our bodies absorb and emit far infrared and any object that is colder than you will absorb your heat. This loss of heat will make you feel cold. In a cold room, the building will “take” your heat and make you feel cold. But if we heat the walls, ceiling and floor of a building (“the Thermal Mass”) using Herschel Infrared, the room will stop taking away our body heat and radiate back the infrared, making us feel warm.
This is a warmth that is almost impossible to achieve with central heating that just heats the air and does very little to heat the thermal mass of the building.
Infrared heating has the following advantages over convection:
- Higher rate of heat transfer per kilowatt
- Lower kW capacity requirement;
- Lower running time;
= higher efficiency
- Establishes “thermal mass” – the room becomes a 360° Radiator;
- You do not have to heat the entire volume of a room’s air to become warm;
- You can “Zone” an infrared heater (i.e. heat just the area you want to). This is difficult to achieve with a heater that heats the air;
- No moving parts = Lower maintenance. There are no moving parts in an Infrared Heater.
- More accurate to control.
