Barely used hayward h400fdn 400,000-btu natural gas heater. We installed and used for less than 3 months. The heater worked well in our facility but we are currently upgrading to an asme certified model. Please do not hesitate to message me with any questions. Hayward h400fdn universal h-series low nox 400,000 btu natural gas pool heater. The hayward universal h-series gas heater is the “universal” energy efficient remedy for any new or existing 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 a 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. Presenting hayward®’s world-class heater with an earth-friendly conscience, the universal h-series heater! The universal h-series low nox heater has an 84 percent industry-leading thermal efficiency and complies with all current california air quality emission standards.
Hayward’s universal h-series heaters represent innovative heating technology for pools and spas. Its hydraulic performance also saves energy by reducing the circulation time of the pump.
It can raise the temperature of an 800 gallon pool 30 degrees in less than an houryou’ll feel the benefits the moment you step into the water. This approach to heating your pool is an efficient use of energyshowing once again our commitment to developing earth-friendly products. Other performance and efficiency-enhancing advances include stainless steel burners, corrosion-resistant finn plate heat exchangers with cupro nickel, and insulated fire tile combustion chambers. This traps the heat unlike other forms of insulation delivering the highest degree of performance from every btu.
Equipped with an led control panel it monitors heater performance for added convenience and maximum comfort with minimum effort. The ignition system delivers dependable lighting and reliable operations with just a touch of a button. The forced draft system constantly moves air through the combustion chamber to eliminate all outside weather variables affecting heating performance, such as wind conditions, eliminating the need to install a high-wind stack. Additionally, the universal h-series heater is easy to install and combines advanced technology with universal-fit flexibility making it virtually compatible with any new or existing equipment pad.
This heating mixture sustains your swimming season, adds to your comfort, is energy efficient, and reduces your fuel costs. This low nox emissions heater is perfect for you and the environmentall at the same time. 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 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. Control panel – easy-to-read l. Control panel provides digital temperature readout and diagnostics for quick identification of components that might need service.
