The Hayward W3HS135FDN Universal H-Series Natural Gas Pool & Spa Heater with OmniX delivers 135,000 BTU in the smallest cabinet Hayward builds, sized for above-ground pools - and it is the only heater at this capacity with embedded smart automation.
OmniX puts the intelligence in the heater itself rather than in a separate control panel: app-based remote temperature control, scheduling, wireless coordination with pumps and other equipment, and advanced diagnostics. An optional OmniX Gateway extends control beyond Bluetooth range.
A cupro-nickel heat exchanger with Hayward's Totally Managed water flow design resists salt water and chemical corrosion. The unit accepts 20 to 125 GPM, is rated for elevations up to 2,000 feet, and operates in ambient temperatures down to 40 F.
