Hayward H-Series Electronic Low NOx Swimming Pool Heater 250,000 BTU Natural Gas


Sku: H250FDN

Description Technical Specs

Hayward’s H-Series Electronic Low NOx Swimming Pool Heater is an ingenious choice for both new systems and existing system upgrades due to its advanced technology and universal flexibility. A towering 83-84% thermal efficiency rating in this industry makes this 250,000 BTU natural gas pool heater a strong energy saver and economical way to warm up your swimming pool or spa.

While using innovative technology to increase an 800 gallon pool temperature 30 degrees in less than 1 hour, highly efficient hydraulic functions conserve energy by cutting pump circulation time. High performing stainless steel burners, insulated combustion chambers, and Cupro-Nickel corrosion-resistant heat exchangers shelter a significant amount of heat maximizing performance from each BTU. The Hayward H-Series Electronic Low NOx Swimming Pool Heater’s LED control panel monitors functions to ensure maximum comfort with little effort. This natural gas pool heater also houses an ignition system that provides dependable operations and lighting with an easy push of a button.



Superior Hydraulic Performance - New polymer header provides superior hydraulic performance to save energy and protect against the damaging effects of erosion from high flow conditions for improved reliability.
Designed for today’s larger diameter plumbing systems with 2" x 2 1/2" CPVC unions.

Forced Draft System - Forced draft system constantly moves air through the combustion chamber at a precise flow rate, eliminating all outside weather variables that can effect the heating performance, such as high wind conditions — without a high wind stack.

State-of-the-Art Finn Plate Heat Exchanger with Cupro Nickel - Our 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 even in salt-based, high flow or aggressive water chemistry set ups.

L.E.D. Control Panel - Easy-to-read L.E.D. Control Panel provides digital temperature readout and diagnostics for quick identification of components that might need service.
