Product details

The Hayward HAXHXA1403 is the heat exchanger assembly for the H400 H-Series gas heater. It is supplied as a kit that contains the parts needed to complete the replacement, and it covers the millivolt, ED1 and ED2 versions of the heater.

The design

The exchanger uses the patented single header V baffle arrangement. That geometry moves heat into the water quickly and leaves virtually no condensation inside the cabinet, which is one of the things that shortens the life of a heater when it goes wrong. The tubing is protected with cupro nickel, the tougher of the materials Hayward specifies, for durability in harder or more aggressive water.

Before you order

Confirm the heater size on the data plate. This assembly is the H400 and does not cross to the smaller models in the range. The union nuts, header o-ring set and CPVC flange nipples around the exchanger are separate part numbers, and a heater old enough to need an exchanger is usually worth refreshing those at the same time.

Questions and answers

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

Which heaters does this fit?
The H400 size H-Series heater, in the millivolt, ED1 and ED2 styles.
Will it fit a smaller H-Series heater?
No. This assembly is the H400 size. The smaller H-Series models take a different exchanger.
Does the kit include everything for the job?
It contains the parts necessary for the replacement itself. Items outside the exchanger, such as the H-Series union nut, the ED1 and ED2 o-ring set and the CPVC flange nipples, are separate parts.
Why cupro nickel?
Cupro nickel is the more resilient material of the two Hayward uses, which is what gives the exchanger its durability and service life.
