Hayward 400K BTU H-Series OmniX Propane Heater, W3HS400FDP, Cupronickel, Low NOx

Hayward Universal H-Series Heater 400,000 BTU - Propane w/ OmniX

Universal H-Series pool and spa gas heaters are engineered for easy drop-in replacement, with direct compatibility to Hayward plumbing adapters. At the center is Hayward’s Universal Display, delivering a consistent, intuitive control experience across Omni®, OmniX®, and competitive automation systems. With OmniX embedded intelligence, the heater provides enhanced programmability, advanced diagnostics, and seamless remote connectivity.

Features:

  • Cupro-nickel heat exchanger offers exceptional protection against corrosion and premature failure caused by unbalanced water chemistry
  • Totally managed water flow boasts industry-leading hydraulic performance coupled with lightning-fast speed-to-heat capability
  • A universal junction box allows either left or right electrical installation
  • Front-panel-only access provides easy service and maintenance, avoiding the problems and costs associated with front-and-back-panel access heaters
  • Low NOx emissions meet clean air quality standards
  • Backwards Compatible OmniX Retrofit Kits available for existing Universal H-Series gas heaters 2016 or newer with the current bezel cutout

Optional OmniX Gateway: The OmniX Gateway is an add-on that connects the heater to Hayward’s OmniX app for remote monitoring and control from a smartphone. Without it, the heater can still be operated locally or through compatible wired automation.
