Product details

The Hayward W3HS135FDN is the 135,000 BTU natural gas model in the Universal H-Series line, built for above ground pools and spas and fitted with OmniX embedded intelligence.

Heat exchanger and flow

The heat exchanger is cupro-nickel, which is the material that holds up when water chemistry drifts out of balance rather than pitting and failing early. Totally managed water flow gives the H-Series its hydraulic performance, and that flow paired with the BTU rating is what produces fast speed to heat.

Controls

At the front is Hayward Universal Display, the same panel behavior across Omni, OmniX and competing automation systems, so a tech who knows one knows them all. OmniX adds enhanced programmability, advanced diagnostics and remote connectivity on top of it.

Installing and servicing

Everything is reached from the front panel, so the heater does not need clearance behind it for service. A universal junction box takes the electrical run from either side, and a 3 ft plug-in 120 volt cord powers it. Low NOx emissions meet clean air quality standards.
