Product Overview

The Pentair 474060 Heat Exchanger Kit is an OEM replacement tube sheet coil / heat exchanger assembly designed for select Pentair MasterTemp and Sta-Rite Max-E-Therm pool and spa heaters. The heat exchanger is one of the main components responsible for transferring heat from the burner system into the pool water.

This kit is commonly used when the original heat exchanger is leaking, scaled, corroded, or no longer transferring heat properly. Replacing the heat exchanger can help restore proper heater operation and heating performance when the rest of the heater is still in serviceable condition.

Customer-Facing Q&A

What does this heat exchanger kit do?
The heat exchanger transfers heat from the heater’s combustion system into the pool or spa water. If it fails, the heater may leak, overheat, heat poorly, or shut down.

Is this the same as a tube sheet coil assembly?
Yes. This part is commonly referred to as a heat exchanger kit, tube sheet coil assembly, or coil assembly.

Which heaters does Pentair 474060 fit?
This kit is commonly used with select Pentair MasterTemp 300K and Sta-Rite Max-E-Therm 333K heater models. Always confirm using your heater model and serial number before ordering.

Does this work on natural gas and propane heaters?
It may be used on compatible natural gas or propane heater models, but compatibility must be confirmed by the heater model and parts diagram.

Is this a DIY repair?
No. Heat exchanger replacement is a major heater repair and should be completed by a qualified pool heater technician.

Should I replace the whole heater instead of the heat exchanger?
That depends on the age and condition of the heater. If the cabinet, controls, burner system, and other parts are still in good condition, replacing the heat exchanger may make sense. If the heater is older or has multiple issues, full heater replacement may be a better option.
