Plumbing the Heating Loop
Once all heat exchangers have been mounted, plan the
routing of the plumbing lines from each heating zone to the
Aqua-Hot. The following guidelines should be used when
planning the coolant loop(s) for the heating zone. The order
of the heat exchangers should consider priority on the loop(s).
Failure to adhere to these installation principles can hinder the
operation of the heat exchangers.
• All plumbing should be installed as fl atly as possible.
• Extreme rises in height should be avoided to avoid any
potential air traps.
• Use ⅝” ID (Inside Diameter) plumbing lines, ¾” SAE J20
type coolant hose, heater hose, or PEX tubing for the
heating loop(s).
• Use wide-sweeping elbows or “bend supports” whenever
the plumbing lines may be susceptible to kinking.
• Plumbing lines should be run in areas where there is no
reasonable possibility that they can be pinched off or
damaged under normal operating conditions.
• Secure all lines where necessary and apply protective
shielding in areas where chafi ng may occur.
• Rubber coated/closed-type clamps are recommended
when securing the plumbing lines.
• Inlet and outlet plumbing lines can be installed with a
straight fi tting or an elbow.
• See Figure 34 for reference.
Instructions:
1. Layout the plumbing lines for all heat exchangers.
2. Label each line with the heating loop number and
designate as an outlet or an inlet line.
3. Connect and clamp the outlet line from the heater to
the lowest port (inlet port) with the longest run for both
heating loops.
4. Connect and clamp a line from the fi rst heat exchanger’s
highest port, and connect the other end to the next
heat exchanger’s lowest point.
5. Connect each additional heat exchanger in the same
arrangement.
6. Connect and clamp the inlet line from the heater to the
highest port on the last heat exchanger to complete
the heating loop.

NOTE: Plumbing heat exchangers in this manner
will allow air to escape naturally. If air is trapped in
any heat exchanger, it will signifi cantly reduce the
exchanger’s overall heating performance.
NOTE: The kitchen and living room heat exchangers (up to
4) must be plumbed together in-series on “Heating Loop
3”. The fresh water tank and bathroom heat exchangers
must be plumbed together
in-series on “Heating Loop 2”.
The bedroom heat exchanger must be plumbed on “Heating
Loop 1”. See the diagram below.
