Hayward H250FDN Universal H-Series is one of the highest rated above ground pool heater on the market. With over 200 customer reviews and a 4 star plus rating on Amazon, it’s a very popular choice amongst people looking for a heater for their pool. It is also a recommended heater in my top above ground pool heaters list.
Without any delay, let’s begin with our Hayward H250FDN review.
This heater has a capacity of 250,000 BTU (British Thermal Unit) which is sufficient to heat around 15,000 gallons of water, or roughly a pool size of 750 square feet making it an idle option for most households. Since it is a natural gas heater, it will require a gas connection to function. It comes with the option of having the water, gas and electric connection (for the electric ignition) on either the left or the right side of the device making it very versatile. It also offers both 110v and 220v electric connections.
The Hayward H250FDN has got a digital LED control panel which makes operating this above ground pool heater a breeze. Hayward has put some work into making this heater efficient and eco-friendly. They claim to provide energy savings of up to 18% when compared to other heaters in the same category, which reduces the gas bill quite significantly. Another environment-friendly feature is the reduced amount of NOx (which can react to form ozone) released into the atmosphere by the heater.
The heater contains Hayward’s patented polymer header design which works to provide a superior hydraulic performance for the heater. This not only protects the heater from the damage caused due to erosion but it also helps to reduce the energy expenditure of the heater.
Another highlight of the H250FDN is the use of Cupro Nickel in their heat exchanger used to transfer the heat within the heater. Cupro Nickel is an alloy of Copper and Nickel which provides excellent corrosion resistance against sea/salt water. This is the same material used to make coins in many countries! Since this material is used in the heat exchanger of the heater, it increases the durability of the heater significantly!
As a matter of fact, this is the heater owned by many of my friends who use it to heat their above ground pools, and all of them love the performance they get out of this product. They’ve had it for more than a year with little to no issues. The total heating time for this pool can vary anywhere from 2-4 hours depending on the size of your pool.
A complaint that few people have about this above ground pool heater is that it’s quite loud. From my personal experience, I wouldn’t say that these complaints are entirely wrong but, the noise created by this heater isn’t much louder when compared to other heaters that are available. Yes, you will be able to hear it working in the back, but it won’t be uncomfortably loud or something that will affect the fun time.
Altogether, the Hayward H250FDN Universal H-Series Low NOx 250,000 BTU is a great option for someone looking to buy a heater for their above ground pool which offers excellent performance. Although it is a bit heavy on the pocket, it’s well worth the price.
