Extended swimming season!
Have had zero issues with this heater. Works well for my 18'x54" above ground pool. Easy to install, would recommend for anyone with a smaller pool.. This is our second season using this heater, and haven't had any issues.

Pentair is a joke!
Bought one of these and ran it for 5 months. The heat exchanger went bad and is not covered under warranty. These guys are a joke! I had a Pentair Minimax 100 that lasted for 20 years. I would never buy one of these again. $1,900.00 shot down the drain. Pentair had me call one of their service folks only to tell me it was $160.00 for the call and a 5 month old heater was not covered ... show more

Great costumer service
Great product. Working fine fir us until now no problems. Just when you get it if on the side says lp means liquid propane. If not means natural gas. By mistake get wrong one and they replace it right away. Discounted pool service great costumer service. Thank you

Learn from my mistake
Extremely disappointing experience. I purchased this pool heater new and, due to weather and pool opening season in Northern Pennsylvania, had it professionally installed when ready for first use. Upon startup, the heater immediately failed, displayed repeated error codes, would not ignite, and never produced heat — it never worked from day one. We spent hours troubleshooting using the manufacturer manual and online guidance, verifying gas flow, water circulation, and setup were all within proper operating range. What turned a frustrating situation into a terrible experience was the seller’s handling of the issue. A return was discussed and Amazon customer service advised the item was eligible for return due to being defective. However, despite this, the seller refused to provide a prepaid return label or even a return address for this large/heavy item and instead insisted we pursue manufacturer warranty repair on a brand-new heater that never functioned upon first use. Most concerning was being repeatedly accused of damaging the heater despite immediate reporting, documentation, photographs, troubleshooting efforts, and proof of installation conditions. For a major purchase of this cost, I expected accountability and customer service — not weeks of frustration, hours spent with customer service, and resistance to resolving a defective product issue. Buyers should carefully document everything from delivery through installation and understand the return process before purchasing. ... show more

Happy with purchase.
Heated my 21 foot round pool fast. Can't wait until spring of 2024 to test it out to warm it up and get an early start to swimming.

I will no longer purchase this brand
We bought this heater two years ago. We use to have one prior to this that lasted 8 years! This time it only lasted 2 years. We tried to troubleshoot it and nothing. We tried contacting the company and no return call.

Find a better cost option - only lasted 2 years
Thought this item would last longer but it is officially a cracked manifold and leaking. We had 2 years with it total, for the price it should last longer.
