ABOVE FLOOR INSTALLATION
(One-Way Serpentine Patterns - Typical)
Constant Spacing Outside Wall Concentrated Spacing
(Wall with large window area or cool wall)
These drawings are conceptual only. Consult Weil-McLain Radiant Guides or Software for actual project layout.
NOTE FLOW DIRECTION
! The warmest water is directed next to the outside wall.
DISTANCE TO WALL
!
! Keep the tubing 4 to 6 inches from the walls.
This will reduce the chance of damage due to drilling,
sawing or nailing.
USE HEAT EMISSION PLATES
!
!
!
Snap the tubing into AlumiPex Heat Emission Plates
placed on the sleepers.
These plates spread the heat evenly to the floor and ensure
that the tubing is maintained in tight contact with the
flooring above.
Staple the heat emission plates to the sleepers on one side
only to allow the plates to conform as the flooring or
subfloor is installed.
PASSAGE UNDER WALLS
!
! Avoid running tube under walls if possible.
Where tubing must run under a wall, mark the framing
above for 6 inches on either side of this location so no
fasteners will be driven into the framing near the tubing.
CLOSER SPACING
! Tubing is often spaced closer near outside walls with cool
surface temperatures or large window areas.
BEND DIAMETER
Maintain a MINIMUM bend
diameter of:
!
!
! 1/2“ Tube - 6 inches
5/8“ Tube - 7 inches
3/4“ Tube - 8 inches
