Product details

The Pentair 475623 is the TitanTough heat exchanger for the ETI 400 pool heater. It is the genuine Pentair replacement part.

What it is

The heat exchanger is the part of the heater that pool water actually passes through. Combustion heat crosses into the water there, and every other component in the cabinet exists to feed, control or protect that exchange. When the exchanger fails, the heater is out of service until it is replaced.

Before you order

This exchanger is specific to the ETI 400, so check the heater label. Replacing an exchanger is a significant job, and it is worth having a service tech confirm the diagnosis before committing to the part.

Questions and answers

What people ask about this product, answered by our pool techs.

Which heater does this fit?
The Pentair ETI 400.
Is it the genuine Pentair part?
Yes. It is Pentair part 475623.
What does a heat exchanger do?
It is the component that carries pool water through the heater so combustion heat can pass into it. Everything else in the heater exists to feed and control that transfer.
How do I know the exchanger has failed?
Water where it should not be inside the heater cabinet, or a heater that will not hold pressure, points at the exchanger. A service tech should confirm before a part this significant is ordered.
