4.2 Line-Set Routing
Selection of line-set route should be discussed with homeowner with consideration to aesthetics,
complexity and cost of installation (Fig. 4.2.1). Line-set through home will have lowest heat-loss and
possibly shortest length (Fig. 4.2.1 option 1). Interior line-set should not run next to bedrooms or day-
time living space as some vibration noise from pump may be transferred through line-set. Interior line-
set may be more appropriate for bungalow or single-storey applications.
Line-set may penetrate roof into attic (Fig.
4.2.2) and drop from soffit down exterior
wall to above foundation or through
foundation to mechanical room (Fig. 4.2.1
option 2). This may facilitate installation and
minimize vibration noise transferred through
lines. Exterior line-set and insulation must be
protected by molding, electrical conduit or
false downspout that matches existing siding
or eavestrough (Fig. 4.2.3). Exterior line-set
may be best for two or three-storey
applications.
Line-set may run around eave and down
exterior wall if access to attic is limited (Fig.
4.2.1 option 3). All exterior insulation shall
be protected from ultraviolet radiation and
moisture damage. Line-set of rack-mounted
collectors on ground may be run
underground through conduit such as big-
‘O’ to protect insulation (Fig. 4.2.1 option 4).
For new homes, consider installing 3 – 4” diameter PVC
or ABS chase from attic to hot-water tank location. This
will facilitate future removal or replacement of line-set if
necessary.
