The water in a radiant system has a capacity to transport energy 3,500 times greater than air, so it can heat (and even cool) using less energy than a forced-air system. This amounts to greater comfort at a lower thermostat setting, which provides lower energy bills.
In fact, more people are comfortable with radiant floor heating at a lower thermostat setting than with forced-air heating at a higher thermostat setting.
Additionally, a radiant heating system works in zones, allowingdifferent areas of a home to heat at different temperatures. This allows typically chilly rooms, such as bathrooms, basements and entryways, to receive more heat when needed. At the same time, rooms with less traffic, such as a den or formal dining room, can be set to a lower thermostat setting, makingthe system even more energy-efficient.
Key Benefits
Concentrates heat evenly near the floor where people are located
Eliminates cold drafts as well as noisy fans, furnaces and ductwork
Ideal for allergy sufferers because it doesn’t circulate dirt, dust or other airborne pollutants throughout a home
Concealed under the floor for a more aesthetically pleasing environment — eliminating the concern of blocking vents with furniture
Easily integrates with alternative energy sources, including geothermal, solar, waste and biomass
Can help a home earn LEED® points for reduced energy consumption
Potentially saves up to 40% in energy costs
Other Radiant Applications
Snow and Ice Melting: The concept of radiant floor heating can also make driveways and walkways clean and dry during the winter, eliminating the need for salting, sanding or shoveling. Uponor snow and ice melt systems help lower maintenance costs, reduce dangerous accidents associated with slippery walkways, extend the life of concrete and asphalt, and eliminate disturbing noise from snow blowers as well as the problem of tracking salt and sand into your home.
Forced-air Heat vs. Radiant Heat
Radiant keeps heat near the floor where people are located.
