Hayward W3H135FDN H-Series Pool/Spa Heater, 135k BTU, Natural Gas Model

Reliable heater

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. 🤷‍♂️

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.

Easy install.

This pool heater works great! It increases the water temperature at about 1 degrees per hour. We have about a 9000 gallon pool. I highly recommend Hayward!!!

Very efficient and cost savings compared to local retailers

JunkHeater stopped working after 10 months….. Visit the BackyardPoolSuperstore. Said call mfg… mfg no resolution. Will have to pursue Amazon for help with this seller

JUNK! Had less than a year and the heater core started leaking. Contacted customer service and was provided a new one for free. Installed it myself and worked great for 4 months. Then started leaking again. Tryef to contact customer service again and no response. I checked my water quality several times a week and it was fine. I GUESS A WARRANTY IS AS ONLY GOOD AS THE COMPANY WHO BACKS IT!
