Radiant floor heating involves installing water heated tubing under your home's floors. With a Radiant floor heating system, the heat from the floor warms everything it touches and radiates throughout the room from the ground up. Think of Radiant floor heating like heat from the sun. On a sunny day, if you step from the shade into the sun, you'll feel warmer even though the air temperature is basically the same. This is how radiant floor heating works. The temperature throughout the room is more constant than your standard forced-air system, where the air rises, cools and then falls to the floor.
