According to the U.S. Department of Energy, radiant heat is more efficient than baseboard or forced air systems. Rather than just blowing hot air around the room in bursts, radiant systems slowly and steadily charge the floor with heat, keeping it where you want it, longer. Hydronic, or water-circulating, radiant systems are best for new construction or large additions. Electric radiant is an easy option for a smaller space like a bathroom and uses less than 15 cents of electricity per day!
