Radiant Basics
Forced Air Heating
As hot air rises, temperature distribution becomes uneven and drafts result. With forced air heating, even though the thermostat reads 72, you may be uncomfortable because the temperature at the floor is 68, while the temperature at the ceiling is 80 or 90. You end up with a hot head and cold feet.
Radiant Heat
Radiant floors spread heat evenly throughout the room. This warm floor will provide direct, conductive warmth to anything in the room. Because objects in the room have been heated, not the air, radiant floor heating eliminates the hot and cold spots. It is easy to see how radiant floor heating is more efficient than forced air. Remember heat flows from hot to cold while hot air rises. A warm floor will keep your feet cozy, while a cold floor will steal heat out of your feet.
Comfort is the primary reason for choosing a radiant heating system.
Radiant heating gives you:
- Warm wood, tile, & vinyl floors
- Multiple temperature zones
- Silent operation
- Constant temperatures
- Dust free heat (no filters necessary)
- Natural humidity (no humidifier necessary)
- Flexibility is another important feature of radiant heating.
Radiant heating gives you:
- Walls & ceilings free of large duct work
- Furniture placement anywhere in a room
- Expandability with future growth
- Compatibility with a wide variety of floor coverings
- Radiant heating is the most economical way to heat a home. Although radiant boilers and forced air furnaces have similar operating efficiencies, heat loss throughout these systems differ sharply. Studies show forced-air systems can lose 25 to 35 percent of their heat before it reaches the room. In radiant systems, the maximum loss in transmission is 7.5 percent, when properly designed, installed and insulated.
