Distance From The Spa; Pool Piping Required - Heat Siphon Z Series Owner's Manual

HEAT SIPHON
longer the distance from the pool, the more heat loss from the piping. Since most of the time the piping is buried,
the heat loss is minimal for runs of up to 50 feet (50 feet to and from the pump = 100 feet total) unless the ground
is wet or the water table is high. A very rough estimate of heat loss per 100 feet of piping is 2500 BTU/Hr. for every
10°F difference in temperature between the pool water and the ground surrounding the pipe, which translates to
about a 3% to 5% increase in run time.

2.5 Pool Piping Required.

IMPORTANT: Allow At Least 12 Inches Of Straight Pipe Between The
Heat Exchanger And Any Coupling Unions Or Elbows To Allow Backpanel

The Dual-Fitting water ports allow you to glue either 1.5 inch or 2 inch (with a standard 2" PVC coupling)
schedule 40 PVC pipe directly into the heat exchanger. No metal heat sink piping is required. The following graphic
applies to all C & Z 200, 250,375 & 575 series heating only and cooling only models:
Heat Siphon's exclusive FULL FLOW Titanium heat exchanger has a minimal pressure drop and requires NO
SPECIAL PLUMBING arrangement. It should be considered as just another length of PVC pipe in your pool filtration
system.
