Radiant Floor Heat
The American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) reports that a home with a radiant floor heat system can have the thermostat set 6 to 8 degrees cooler than the higher temperature of a typical convection or forced air heated home.
This gives radiant floor heat a big advantage of cost savings through less energy usage for the same comfort level.

What is Radiant Floor Heat?Radiant floor heat is a system that pumps heated water from a boiler through tubing. The tubing can be installed by stapling up under an existing floor, laid on top of an existing floor an covered with wood or tile or installed in a thin layer of concrete. The mass of the floor is heated and then radiates up into the room.
At Indoor Air Technologies, we specialize in hydronic (water) systems. They are the most popular and cost effective. The temperature in each room is controlled by regulating the flow of hot water through each tubing loop. This is done by a system of zoning valves or pumps and thermostats. Smaller areas can be supplied with a hot water heater.
Most often in a “dry” installation it involves suspending the tubing underneath the subfloor between the joists. Reflective insulation must also be installed under the tubes to direct the heat upward.
Ceramic tile is the most common and effective floor covering for radiant, as it conducts heat well from the floor and adds thermal storage because of its high heat capacity.
Benefits of Radiant Floor Heat
- No more cold tile or hardwood floors
- Can isolate a single room or area
- Lower part of room warmer vs. rising hot air systems
- Capability of heating patios, driveways, sidewalks
- Low maintenance
- Children & pets love heated floors
