Product details

The Hayward W3HS135FDP is the Universal H-Series heater for above ground pools and spas, rated at 135,000 BTU and fueled by liquid propane. It brings the technology of Hayward's in-ground heaters to above ground installations, with low NOx emissions that meet clean air standards.

Control and connectivity

At the center of the heater is Hayward's Universal Display, which delivers the same intuitive control experience whether the heater runs on its own, with Omni or OmniX, or with a competitive automation system. OmniX embedded intelligence adds enhanced programmability, advanced diagnostics and remote connectivity.

Built to last and heat fast

The cupro nickel heat exchanger gives exceptional protection against corrosion and premature failure from unbalanced water chemistry. Totally managed water flow gives the H-Series industry leading hydraulic performance and fast speed to heat, so the pool or spa is ready sooner.

Installation and service

Everything is reached from the front panel, which avoids the cost and clearance problems of heaters that need access from both sides. The universal junction box accepts electrical entry from the left or the right, and a 3 ft 120 volt plug-in cord makes the electrical hookup simple.

Questions and answers

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

Is this the natural gas or propane model?
W3HS135FDP is the liquid propane version. Make sure your gas supply matches before ordering.
What does OmniX add?
OmniX embedded intelligence gives the heater enhanced programmability, advanced diagnostics and remote connectivity, and the Universal Display provides a consistent control experience whether you run it standalone, with Omni or OmniX, or with a competitive automation system.
What electrical hookup does it need?
A 120 volt outlet. The heater comes with a 3 ft plug-in cord, and the universal junction box allows electrical entry from either the left or the right side.
Why does the heat exchanger material matter?
The cupro nickel heat exchanger resists corrosion and premature failure caused by unbalanced water chemistry, which is the most common way pool heaters die early.
