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.

Worst heating unit you can buy. Pentair does not stand behind their parts warranty. First one I bought went out in 3 yrs. Foolishly bought another Pentair heater and it went out in 7 months. Will never buy any Pentair products again. Very expensive lesson.

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

The heater came with box damage and scratch on front of heater. The heater didn’t come with the high temp unions shown in the picture with the heater. Had several conversations with the seller about getting these parts that were suppose to come originally. The sellers answer was sorry we don’t have the parts and you can return the 120 lb heater if you want. Also they were no help in helping me to figure out what parts were missing. After researching myself I had to order the $60 unions to make hooking up my heater possible. Also the heater didn’t come with a 3/4 inch zinc plug you will need. The heater was a pretty easy to install. Seems to heat my 15000 gallon pool up around 2 degrees an hour.

Excellent service and product condition

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.

Have had heater for a full season and it has operated flawlessly. Install was very easy and comes with per wired whip for 120v. Does not seem to throw enough BTU with variable speed pump over 2500rmp turning pump speed down below 2500 it throws heat to our 14x28 inground pool to heat it. It seems to raise water temp 2-4 degrees per hour depending on water temp.
