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.

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.

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

Purchased this product through Amazon ultimatey came from Leslie pools. Anyway the Pentair 125,000 natural gas was built by an upset factory employee. All the interior gas connections were less than hand tight and the electrical connections inside the main box were never plugged in fully causing the unit to fail on ignition. Thanks for nothing Amazon, Leslie and Pentair. Quality control is a total zero. Saia shipping company was a ten , most polite and helpful driver.

Very simple to install. It is a replacement for our 40 year old Pentair unit that started leaking 2 years ago.

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.

“Too many cooks” Had a twisted path to get any action from Amazon, Doheny, and Pentair when trying to install and also to register this product. I suggest not buying from Amazon to avoid some of the hassles.
