What tube spacing is appropriate for radiant heat applications?
Spacing depends on several variables including the heat loss of a basement or garage area. In residential areas such as basements, 12-inch spacing is most common. It is helpful to space the first few tubes closer together in an area at ground level as in a basement walkout area where heat loss is greater. Likewise, spacing can be wider where heat loss is less, as where the floor is several feet under the surface of the ground, or in the center of a large space.
