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!!!!

I installed this myself. If you are not mechanically inclined, I would hire a professional.

Perfect fit and works as described. The price was okay too.

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!!!!

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.

On time, packing done right and installing was a snap.

It’s easy to install . The question is how long we’ll it work. The original heater lasted 15 years now the heat exchanger only last 1.5 years. So in last 3 years I have replaced a heat exchanger in the original heater, then repair the heat exchanger, then replace the whole heater now replace the heat exchanger. Net time I will buy a different manufacturer.
