Hayward Universal H-Series Low NOx Above Ground Pool & Spa Heater with OmniX, 135K BTU, Liquid Propane

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.
