Radiant in-floor heating systems involve supplying heat directly from the floor. These systems depend largely on the delivery of heat directly from the hot surface to the people and objects in the room through the radiation of heat. Radiant floor heating depends heavily on convection, the natural circulation of heat within a room caused by heat rising from the floor.
Radiant heating has a number of advantages. It is more efficient than baseboard heating and usually more efficient than forced-air heating because no energy is lost through ducts. The lack of moving air can also be advantageous to people with severe allergies.
While forced air heating systems leave the ceilings warm and the floors colder, radiant heat provides a more consistent temperature throughout the room with the temperature varying only 2 to 4 degrees from floor to ceiling. Your home will be more comfortable at a lower heat setting, saving you money in utility bills.
You will have less of a need to run a humidifier as the air does not dry out with radiant heat like it does with forced air heat. This is better for people who suffer from dry skin irritation in the winter. Those with arthritis or circulatory problems will appreciate the feel of a warm floor rather than a cold one, especially during our chilly Minnesota winters.
