Product details

The Pentair 476382 is the TitanTough heat exchanger for the ETI 250 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 250. The ETI 400 uses a different exchanger (Pentair 475623), 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.

Note: the product photo shows the ETI 400 heat exchanger (475623) for reference. The ETI 250 heat exchanger you receive is part 476382.

Questions and answers

Is it the genuine Pentair part?

What does a heat exchanger do?
