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.

The Applicable Warranty Period is one (1) year from the Purchase Date. The warranty does not cover damage caused by improper water chemistry.

250,000 btu for not quite 2 seasons. Heat exchanger is gone, leaking water everywhere. Now check out the price for a heat exchanger; throw the furnace in the garbage because it doesn’t make sense replacing parts for that price. This was by far the worst pool heater I have ever owned. I used to be a Hayward fan, but now, I will NEVER EVER buy a Hayward product again. Absolute Garbage! As a side note, I had this heater professionally installed by a pool company and had it plumbed in by a certified gas fitter. I kept it inside a pool shed and had it vented through the roof. This was the first heater I “babied” due to the high price and it still couldn’t perform for 2 full seasons.

This is a really nice gas pool heater. It is very easy to use. Our gas tech had it hooked up in no time. It is quiet and heats up our pools pretty quickly.

Margaret L     |    August 11, 2020

Starts up every time and works great. Very pleased with this product.

Joan and Dan     |    September 18, 2017

Super impressed with this heater. Heats our 24ft round pool from 70 to 80 in only a couple of hours. Easy to hook up and easy to operate. Best price on the market, just can't go wrong with a Hayward in my opinion,we just love our new addition. Made our summer for 2017. Thanks for the great service once again.

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.

Claire     |    March 19, 2014

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.

Cliff     |    February 25, 2014

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.
