With a radiant heat system, heat is spread evenly over the entire floor, which heats the room more comfortably and evenly. This allows you to feel warmer, even with a lower ambient air temperature. There are no cold drafts or blowers to make cold spots in a room. It also does not dry out the air, which can be very nice during cold, dry winters. Also because no air is blown; pollen, dirt, dust and germs are not constantly spread through the house.
