Product details

The Hayward FDXLHXA1300 is the genuine heat exchanger assembly for the Universal H-Series Low NOx H300FD pool heater. It is an exact replacement for the original, built to the same standard, and fits the H300FD without modification.

When it is the fix

Water inside the cabinet, rust streaking below the exchanger, or a heater that fires but has lost its heating performance all point to the exchanger. Replacing the assembly restores the heater rather than replacing the whole unit.

Before it goes in

The part is specific to the H300FD; other H-Series FD sizes use their own exchanger. And if the old exchanger failed early, check water chemistry before installing the new one. Low pH and high chlorine are what shorten an exchanger's life.

Questions and answers

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

Which heater does this heat exchanger fit?
The Hayward Universal H-Series Low NOx H300FD. Other sizes in the H-Series FD line use their own heat exchanger assembly, so match the part to an H300FD.
How do I know the heat exchanger has failed?
Water dripping from inside the heater cabinet, rust streaks below the exchanger, or a heater that fires but no longer raises the water temperature the way it used to are the usual signs.
Is this an exact replacement?
Yes. It is the genuine Hayward assembly, built to the same standard as the original and designed to fit the H300FD without modification.
Should I check anything else while it is apart?
Water chemistry. Low pH and high chlorine eat heat exchangers, so if the old one failed early, correct the chemistry before the new one goes in.
