Its ground-breaking hydraulic design reduces pump circulation run time, giving you an energy savings of up to 18%! This unit is perfect for the environmentally conscious Pool and Spa owner thanks to its Low NOx capabilities. The Hayward Universal H-Series gas heater meets or exceeds the South Coast Air Quality Management District's (SCAQMD) Low NOx emission standards, making it ideal for use in states with strict air quality guidelines such as California. All Hayward heat exchangers are manufactured with highly resilient Cupro-Nickel, which increases the unit's durability and longevity, even under the harshest conditions.

  • Patented Polymer Header design provides superior hydraulic performance which saves energy and protects against damage due to high flow conditions.

          So far it's great. We have a 24 foot round above ground pool. We have had a Hayward 200,000 btu years ago that got many years of use. We then purchased the Hayward 100,000 btu and that worked well for us but was a bit underpowered for our size pool, that only did 1 degree per hour. Last fall we closed our pool too late and it froze and it leaked. So with much research we purchased the Hayward 250,000 btu propane heater. Electrician hooked it up on 220. It fired right up and heats a bit more tha 2 degrees per hour. Some say it is loud. But its quieter than the little 100,000 btu we had. We hope for years of use. Easy to operate too.
