• Results are obtained while air handler is operating with a dry DX coil and air filter installed.
• Values are nominal and blower performance can vary higher or lower from these values based on the
evaporator coil that is used. Hot water heat air flow performance data includes associated air pressure
drop across a four-row hot water coil for models AH084P/CP, AH125P/CP, and AH166P/CP, and air
pressure drop across a three-row hot water coil for models AH083P/CP and AH206P/CP.
Domestic hot water recirculation circulates hot water through the plumbing system so that instant hot water is
available. Domestic hot water recirculation operates between calls for heat to ensure a balance of comfort for
HVAC heating and domestic hot water. If pairing a Rinnai Hydronic Air Handler with a tankless water heater for
domestic hot water recirculation capabilities, Rinnai recommends the following:
• Use an external recirculation pump controlled by a timer, aquastat, and/or an on-demand type control.
Do not use a Rinnai Tankless Water Heater equipped with recirculation capability
1
with the Rinnai
Hydronic Air Handler.
• Size the air handler based off of the maximum allowable temperature for the domestic hot water system.
Refer to section “5.7.3 Domestic Hot Water Recirculation Piping Diagrams” for domestic hot water recirculation
piping diagrams.
For more information on domestic hot water recirculation, refer to the tankless water heater installation and
operation manual.

Rinnai Tankless Water Heaters equipped with recirculation capability include the SE+ Series featuring ThermaCirc360™
models (Super High-Efficiency Plus RUR Models).
This section is referring to domestic hot water recirculation in the plumbing system and not the circulation
of hot water between the air handler and tankless water heater/boiler.
