off the floor. Tubing higher than this is
subject to damage from nails as
pictures and other objects are hung
on the walls.
Walls are typically installed with their
own manifold pairs as it tends to be
difficult to transition tubing from the
floor to the wall. Also, this allows for
greater ease when trying to balance a
system. In most cases, the wall will
use less tubing and typically shorter
tubing lengths than can be installed in
the floor or ceiling.
Recessed Wall
Another method for installing a wall
or ceiling is to first install a drop
panel. This drop panel will usually
consist of a 1" insulation board, but
may also be a 1/4" plywood. Both will
be supported by runners attached to
the sides of the studs or rafters.
