  • Lot of shysters listing in this space
Size: 250,000 BTU (W3H250FDP)
If the price seems to be too good to be true, it is. Unfortunately, Hayward has the best products and they don't care about their customers. This unit replaced an identical unit that lasted 12 years. Buy an aftermarket warranty because Hayward probably ain't gonna help ya if you have problems one day after the warranty period. ... show more

  • Great heater
Size: 250,000 BTU (W3H250FDP)
Price was the beast I could find on the internet. It was not too hard to install, but I had help from a friend, that is a licensed plumber, and my Brother in law who is a licensed electrician. So I was basically muscle and tool getter. After going crazy with the LO code. I finally watched a video and it explained that the problem was LOW WATER PRESSURE. I went through every water line and after fully taking apart my filter, and cleaning it, the heater worked as expected!!! Great product and the family was enjoying the pool the next day. ... show more

  • Easy to install and use
Size: 250,000 BTU (W3H250FDP)
Was a piece of cake to install and startup. Was well informed about how much propane is needed to heat a pool, so I was not surprised. With a 26K gal. pool starting at 60 deg F, increased about 1.6 deg per hour, or about 2.3 gal of propane per hour. Our goal was to extend our swimming season in NE Texas. April is probably a bit early as we discovered due mainly to the difficulty of retaining the added heat. In the future will probably wait until May before using for the season...with adequate pool covers. ... show more

Product was late in arrival and then defective once I installed it. Seller at first seem like they were going to help, but once I sent pictures of the leaking system they used every excuse not to help and referred me to the manufacturer. You can't reach the manufacturer. There is no warranty on this product. I now have an over $2600.00 brick by my pool. A-Z claim with Amazon was denied. ... show more

  • Great unit
Size: 250,000 BTU (W3H250FDP)
Newer version of our old pool heater, but this one seems more efficient. It's much quieter, heats more efficiently when using propane, and the casing seems more rodent resistant, which is key. Our old unit had a lot of damage inside from rats nesting inside.
