The Hayward 250 000 BTU natural gas pool heater has a build quality that’s hard to beat. It’s manufactured by Hayward, and it has the model number H250FDN. This pool heater is made of stainless steel, so it should last you for years without rusting or corroding. This particular unit is also a heat pump–this means that it can move heat from one place to another with relative ease, which saves energy over other types of heaters like gas burners or electric elements.

The capacity on this model is 250 000 Btu/hr (British thermal units per hour), meaning that if your pool has an average water temperature of 80 degrees Fahrenheit then you’ll need approximately 1 500 gallons per hour flowing through this device in order for it not only function properly but also be able to keep up with all the demands placed upon it by your pool system at any given time

Hayward H250 pool heater Performance

The W3H250FDN Hayward H250 is a natural gas-powered heater that puts out 250,000 BTUs of heat. This means it can heat your pool quickly and efficiently, even when you’re in the middle of winter or early spring. The unit has an insulated cabinet for added protection against the elements, and it comes with a built-in automatic ignition system to make starting up your heater as easy as possible.

It is designed so that it only uses 4% more energy than other models on the market today–a significant improvement over older heaters that may have been more expensive but also used much more power than necessary (and thus cost homeowners more money over time). In addition, this particular model has been certified by Underwriter Laboratories Inc., meaning you can trust its safety standards without worry!


Durability is a must for any pool heater. The Hayward Universal H-Series Heat Pump Natural Gas Pool Heater is built to last, with a durable steel cabinet and stainless steel exhaust parts. This means you’ll be able to enjoy your new heater for years to come without worrying about it breaking down or needing repairs.

The durability of this pool heater is better than other heaters on the market today because they use less plastic components and more metal ones in their construction. The result? A product that’s strong enough to withstand harsh weather conditions without breaking down over time!


  • Installation of Hayward 250 BTU pool heater is easy. You can install this heater yourself, but it’s best to hire a professional to do the job.
  • Difficulty level: Low

You’ll need a pool heater installation kit and manual or guide, which you can find at your local pool supply store or online through retailers like Amazon. The kit should include everything you need for installation, including hoses and clamps for connecting it directly to your gas line (if applicable).

Hayward H250FDN pool heater warranty

Hayward is known for its quality products and the W3H250FDN is no exception. The three-year warranty is one of the most robust in its class, which shows that Hayward stands behind their product. With a track record like this, you can trust that your pool heater will last for years to come!

The best part

The best part of this heater is its ease of installation. The Hayward W3H250FDN has a flexible design that makes it easy to install in most pools, and it doesn’t require any special tools or equipment. This makes it perfect for people who don’t want to hire an expert or take on additional repairs costs by hiring one themselves.

It also works well in a variety of weather conditions, making it ideal for use anywhere in the country–even if you live where temperatures drop well below freezing during winter months!

The Worst Part of Hayward H250 Pool Heater

The worst part of this heater is the cost. It’s not cheap, and you’ll have to pay for installation as well. The second worst part is that it’s difficult to install yourself if you’re not familiar with gas heaters. The third worst thing about this product is that there are no warranties on parts or labor, so if something goes wrong after the warranty period expires, you’ll be stuck paying for repairs out of pocket (or just buying a new heater).

The fourth most annoying thing about this product is its lack of an on/off switch; instead, there are two knobs–a power knob and a temperature knob–which means that once turned on by either knob being turned all the way up or down respectively (or left untouched), there’s no way off until either knob has been reset back into its original position again!

Our expert’s words

This H250 Pool Heater is the best way to heat your pool water. It’s easy to install, energy efficient, durable and has a great warranty. It also has a good build quality that will last for years.
