Radiant floor heating isn't a new technology, but it's making a comeback in many new homes.

How it works

A radiant heating system uses electric cables or small tubes of hot water embedded in a concrete floor, under a tiled floor or attached to the underside of the subfloor.

Instead of heating air and circulating it throughout the house, radiant heat warms objects - carpet, furniture and even people. Less energy is needed to transfer heat directly to people, rather than fill the entire room with heated air like a forced-air furnace.

Homeowners with radiant floor systems claim it's the most comfortable heating option. Heat is produced evenly across the entire room, eliminating hot and cold spots common with forced-air systems.

Radiant heat also warms from the bottom up - when your feet are warm, the rest of your body feels warm too.

Radiant systems are also very quiet, with no noisy blower fans or clunky radiators, and they don't circulate dust and allergens like forced-air systems. During the winter, the humidity remains at a more comfortable level.

And best of all, radiant heating systems are energy-efficient - you can set the thermostat of a radiant floor heater six to eight degrees lower than usual and have the same level of comfort. Energy savings of 15 to 20 percent are common.
