Review: Very good! - 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. 🤷‍♂️ Review: Sad piece of junk - 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.
