## Customer Reviews

### ⭐⭐⭐⭐⭐ Reliable
*by S***Y on July 15, 2025*

Reliable heater

### ⭐⭐⭐⭐⭐ Very good!
*by J***M on August 9, 2024*

Make sure you get the extended warranty-these heaters are very fragile. Always mixed the right chemicals and test your pool twice a week.Heats up your pool in 2-3 hours maybe less depending on your size. Get ready for that gas bill to sky rocket. 🤷‍♂️

### ⭐ Sad piece of junk
*by D***3 on June 16, 2025*

Quit working after only 3 seasons. Before I am blamed for not properly maintaining it, rest assured it was professionally kept, as I use a pool maintenance service. It is now $760 more than what I paid for it. The heater repairman says that the problem is probably the gas tube and/or burners and the whole thing would need to be dismantled to even see if those things are the problem. He said i would be about 2/3 of the way to buying a new one after the service call. I also had to pay $187 for him to tell me it can’t really be fixed without taking it apart and recommended I try to do it on my own.Pool heaters are notoriously pieces of **** that last 4-7 years max. I would not buy another Hayward. Period.
