Comfort is hard to define and is best understood as the absence of discomfort. Perhaps the most remarkable thing about radiant heat is what you won't notice. There are no forced air registers to see. No noise or dust from mechanical blowers. No hot air blowing on you. No hot air collecting at the ceiling, wasting energy. No cold floors to chill your feet. The mild warmth of a radiant floor is a subtle experience and always feels just right. Comfort is hard to define and is best understood as the absence of discomfort.
