Hayward Heater Universal H Series Low-NOx 400.000Btu H400FDN

Natural Gas
The Hayward Universal H-Series gas heater is the universal energy efficient remedy for any new or existingswimming pool or spa. An industry leading hydraulic design reduces circulation pump run time to provide energy savings of up to 18% when compared to less efficient competitors. The energy efficiency of the Universal H-Series gas heater combines with environmentally friendly low NOx emissions, a standard cupro nickel heat exchanger and ultimate installation flexibility on new or existing equipment pads to responsibly heat aswimming pool or spa today and for years to come.

The forced draft system in the Universal H-Series constantly moves air through the combustion chamber at a precise flow rate eliminating outside weather variables that can affect heating performance. Wind conditions are eliminated and there is no need to install a high-wind stack.

NOTE: Hayward Universal H-Series 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

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 todays larger diameter plumbing systems with 2in x 2.5in 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
