Underfloor heating, known as radiant heating, is a type of heating system (as the name implies) that is installed under flooring, eliminating the need for unsightly radiators or warm air ducting that must be cut into ceilings, walls, and floors. Radiant heating may be either hydronic (water/fluid flowing through pipes) or electric (electric resistance heating elements).
The comfort level of the floor surface is the key to determining what temperature is necessary to achieve proper comfort. Building occupants – especially homeowners who might be more inclined to walk around without shoes — may feel uncomfortable with floor surfaces that are too warm or too cool.
To provide adequate comfort, many factors must be taken into account, including the size of the room, the construction of the home, R-value of the windows, HVAC systems, the number and age of the occupants, and the interior finishes that may be directly affected by these requirements.
