Rinnai N Series Replacement Secondary Heat Exchanger (PN-140)
The secondary heat exchanger on a Rinnai N Series water heater recovers heat from the exhaust gases that would otherwise be lost through the flue and puts it back into the water heating process. It's a core part of what makes a condensing appliance efficient, capturing energy a non-condensing design would simply waste.
This genuine Rinnai secondary heat exchanger is made to the original specification, restoring reliable secondary heat recovery where the existing component has degraded. Fitting the genuine part helps the appliance maintain both efficient operation and consistent hot water output.
⚠ Important: Installation and servicing must be carried out by a qualified technician familiar with Rinnai products. Turn off the gas supply and disconnect power before beginning any servicing.

Common Problems This Part Will Fix
Reduced Energy Recovery: Restores secondary heat transfer where the exchanger has degraded.
Higher Than Expected Energy Bills: Fixes wasted energy caused by poor heat recovery.
Inconsistent Hot Water Output: Addresses performance issues linked to reduced heat transfer efficiency.
Ageing or Underperforming Heat Exchanger: Replaces a component reaching the end of its service life.
Why Buy This Product?
A degraded secondary heat exchanger costs money quietly, since the heat it should be recovering just goes out through the flue instead. Fitting the genuine Rinnai part restores that recovery to factory efficiency, improving both running costs and hot water consistency.
