Low NOx Emission, Induced Draft Heaters


Hayward H-Series Low NOx Induced Draft Heaters feature a patented Finn Plate™ heat exchanger with Cupro Nickel for constant heat dispersement, state-of-the-art pre-mix burners for environmentally friendly Low NOx outputs, hot surface Silicon Nitride ignition for instant and reliable fire up, and an advanced L.E.D. digital control panel for simple programming of pool temperatures.




  • Induced draft system constantly moves air through the combustion chamber at a precise flow rate, eliminating all outside weather variables that can affect the heating performance, such as high wind conditions -- without a high wind stack.
  •  Patented single header "V" baffle design heat exchangers allow for long life, fast heating and virtually no condensation. All Hayward heat exchangers are now constructed with highly resilient Cupro Nickel for greater durability and longevity.
  •  Easy-to-read L.E.D. Control Panel provides digital temperature readout and diagnostics for quick identification of components that might need service.
  •  Rust-resistant water path, with injection-molded polymer header and union lock-nut assembly, provides for extended life and simple installation. Exclusive CPVC plumbing kit allows for universal heater replacement and maximum plumbing versatility.
  • NOTE: The Hayward IDL Series of heaters meet the NOx Emission standards set by the California South Coast Quality Air Management Commission for 2001 and the Texas Natural Resource Conservation Commission Code.
