Product details

The Pentair 460747 is the 250K heat exchanger assembly, listed by Pentair under MasterTemp heater water system parts. It is the genuine factory part.

What it is

The heat exchanger is the component that carries pool water through the path of the burner flame. It is the piece that actually does the heating, and it is also the piece that eventually gives out, usually from years of aggressive water chemistry or from scale that has built up inside the tubes and cooked them.

Before you order

Heat exchangers are rated to the heater. This one is the 250K assembly, so read the data plate on your heater and confirm both the model and the BTU rating match before buying. Fitting one is a heater teardown, so it is worth planning to replace gaskets and hardware while the cabinet is open.
