Is radiant floor heat really different from forced air systems?
Yes. Compared to the on/off blast of heated air typical with a forced air system, heat delivered by radiant floors is much more uniform and comfortable. Because of the infrared nature of radiant energy and the large radiating surface of the floors, boilers can be run at lower temperatures, resulting in a higher efficiency for the system. There is also less temperature stratification, especially in rooms with high ceilings. Because the radiating surface is at your feet, the heat is delivered where it is most useful. Radiant floors are quieter than air driven systems and do not have the dust problems associated with moving air through duct work.
