    5.0 out of 5 stars Perfect fit for H250FDN. Genuine Hayward part.
    Reviewed in Canada on October 18, 2021
    Verified Purchase
    My heater was boiling water in the heat exchanger and making a loud knocking sound whenever i turned it on for the last few months. After replacing a bunch of things, it was determined that the heat exchanger had reduced flow in it from some sort of blockage or buildup. Ordered this part, which arrived within 10 days. Installed it myself in about an hour. Instructions were fairly straightforward and the new unit came with all the necessary parts already attached, with a new pressure switch in the box as well. Of course, this was just in time to close the pool for the season, but I'm very happy to know it is ready to start up in the spring!

    My husband loved it because it came with all the gauges already installed. He thought he would have to do that himself. He watched a video and had the installation completed in a few hours. Yay..our heater works again!

    Takes a little time to replace but works great. Worth doing on your own if you are a little bit on the handy side. There’s lots of screws to remove. The step by step directions are very helpful. Saved $1000 doing it on my own.

    Instead of spending 4k all in on a new heater I spent 1500.00 on all new key components including control board. The heater is workin better than the day I bought it.

    1.0 out of 5 stars Piece of Junk: Should Have Learned The First Time!!!
    Reviewed in the United States on October 7, 2023
    Verified Purchase
    I loved my Hayward 250000 pool heater for 10 years! Great craftsmanship and quality product. The heat exchanger finally started leaking after 10 years of use. Being very mechanicaly skilled, I ordered this new exchanger and installed it the 1st. of June 2021! Used it for the next four months and then shut it down for the winter. Used the heater for five months in 2022. The summer of 2023 the heater was used from May until mid-July when this unit started leaking! I wasn't happy, but rlunctly ordered another exchanger and installed it the second week of August. IT STARTED LEAKING YESTERDAY AFTER 6 WEEKS!! I have operated our pool since 1978. I know pool chemistry inside out. The original lasted 10 years. These replacement exchangers are junk, pure and simple!!! Pool water chemistry is not the problem!!! This is a narrative the company wants to perpetuate to cover up the poor quality of these replacements!!!!

    If you’re freaking about how expensive it is to get a new heat exchanger installed and want to try and save $$ by doing it yourself but aren’t sure you’ll be able to- order this now. Anyone who’s the least bit handy and has 1/2 a brain can install this. It’s a lot of unscrewing panels but then once you disconnect the plumbing, it pops right in perfectly with minimal things to connect once it’s in there. It is easy. I’m a single mom and was super worried about biting off more than I could chew- it was not hard. The part came on time and packaged very nicely as to not become damaged during shipping. This is an actual Hayward replacement.
    Also- for anyone out there newer to the pool thing like me. Make sure you have a check valve in your plumbing between the chlorinator and the heater!!!!
