Presenting Hayward®'s world-class heater with an Earth-friendly conscience; the Universal H-Series heater! While all Hayward H-Series heaters are energy-efficient, the Universal H-Series Low NOx heater has an 83-84 percent industry-leading thermal efficiency and complies with all current California and Texas air quality emission standards. The low NOx emission makes it a perfect choice for the environmentally concerned pool owner.

Enjoy a warmer pool this season without your fuel costs skyrocketing. Hayward's 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 hour and you'll feel the benefits the moment you step into the water. This approach to heating your pool is an efficient use of energy; showing 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 environment—all at the same time.

When it works, it works well. BEware of the circuit board after 4-5 years. You will get a "CE" error code which means the circuit board and display board needs to be replaced (a $500 repair) Google the code and see how many people have this problem. I get the code but I'm running my heater off an Aqua Pro control so I bypass the display board and it doesn't affect how it works.
Most efficient heater I have owned. Been a pool owner since 1978 and have had a few heaters. Small foot print, quiet and I love the efficiency of this heater compared to my previous millivolt style. I heard this was the best heater available and seems to be so. Thanks for the quick shipping to my driveway great deal and timely. - Bill
I have this... died and leaks after 5 years... and noone will do anything about it... completely ridiculous. I have have other problems with other Hayward products as well but this has been my biggest headache.
This heater gets the job done really quick! Maybe a bit big for our pool but the heating it can do is great, Hayward always makes a good product.
I really like this heater, bought it for my 16 x 32 pool and it warms it up in only a couple hours. The buttons are really easy to understand and use too which makes it easy for my wife and I to both use.
Very impressed with this heater. Warms the pool water in minutes and is very easy to set the temp. Price here is also much lower than stores.
