๐Ÿš€ Abunda's Overview

This is our summary and key points to consider based on customer reviews.


Most reviewers of the Pentair heater have encountered numerous operational issues with the product, including defective units, problems with the control board, and difficulty obtaining support for these issues. However, for users who found the system functional, it significantly extended the swimming season, offering valuable relief for those living in colder climates.

Pros

  • ๐ŸŠโ€โ™‚๏ธ Extends the swimming season significantly.
  • ๐ŸŒก๏ธ Allows swimming in comfortable temperatures even in colder climates.

Cons

  • ๐Ÿ˜ž Frequently reported operational issues.
  • ๐Ÿ’” Instances of receiving a completely defective unit.
  • ๐Ÿงบ Problems related to the control board and other parts failing.
  • ๐Ÿ”ง Difficulties obtaining support for the warranty or part replacements.

Should I Buy It?

Given the substantial number of negative reports regarding defective units and the lack of support for these issues, caution is advised when considering a purchase. It's crucial to prioritize a reliable source of purchase and potential warranty support. However, when the product does function properly, it notably extends the usability of swimming pools in colder climates.


  • Amazing propane pool heater
Style: New
Great pool heater, works very well, easy to operate. Heats my 12x24 pool well! Highly recommend
Reviewed in the United States on January 3, 2026 by I just opened this cover and installed it on my pool. It is supposed to have an 8 year warranty? When I took it out of the package 3 of the grommets are already off?

  • Very Poor customer service
Style: New
They sent a defective unit and blamed on exhaust system. Did not want to offer replacement/refund or repair. Very poor customer service. Do not buy from them.

  • Pentair Master Temp 150k BTU propane
Style: New
Had a master temp at my old house too, worked great so I purchased this for my new pool here at our new house and purchased a propane one and bought a 40lb tank and a 60lb tank with a low pressure house and regulator and works great. Mainly to help raise pool temp a few degrees in May

  • Junk
Style: New
Donโ€™t buy this, worked 30 hours then quit. I bought an extended warranty but it doesnโ€™t work. They tell you when it quits to pay for a pool person to look at it and send the invoice just to get the part it needs. But if the part is on back order then you have to fix it yourself or wait for the part to come in. ... show more

  • bad control board after 2 days, horrible customer service
Style: New
Purchased this for a rental house in a resort area and after 2 days the control board goes bad. Pentair even after only 2 days would only cover parts and no labor under warrantee. Above that I had to refund renters bunch of $$ because they couldn't use the pool. Horrible customer service and bad product ... show more
