When installing radiant heat in your flooring, it is common to use variable tube spacing. Variable tube spacing is a method of laying out PEX Tubing, in which the tubing is spaced closer together near high heat loss areas. For example, for the first 3 to 4 feet along an exposed wall tubing may be spaced 6" apart to compensate for heat loss. Once the tubing moves away from the wall 12" tube spacing may be used. This is to ensure that your floors and your room receive evenly distributed amounts of heat, no matter where in your home the room is located.
