Radiant Heating

Heated Floors

Radiant heating provides exceptional comfort and energy efficiency. Unlike traditional heating, which relies on small heat surfaces and high temperature heat, radiant heat uses large emitters such as tile floors and lower temperatures. The most popular use of radiant is in floors. Heating elements in the floor (usually small pipes carrying heated water) turn the floor itself into a heating element that warms anything that contacts it, as well as the room itself. Radiant heat can also be delivered through walls, floors and specially designed radiators.

Benefits of Radiant Heat

True Comfort

Imagine your beautiful floors now warm and cozy to the touch

Works Indoors and Out

Radiant heating works beautifully inside your home – under tile, marble, wood, carpet and concrete floors; and inside walls and ceilings. And, as this picture shows, radiant heating can be used outdoors on walkways and driveways, to conveniently melt snow and ice – no more shoveling!


Potentially saves up to 40 percent in energy costs compared with forced-air heating systems

Clean and Healthy

No drafts or fans blowing dust, dirt or allergens into the air


Eliminates noisy fans, popping ductwork and pinging pipes
