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

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.

Reliable heater

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!!!

Easy install.

Can I leave now stars? Bought one of these death devices. Keeps missing firing and backfiring. Trying to send it back. What a pain in the ...this thing could explode or catch on fire. Hayward or Amazon could care less

Very efficient and cost savings compared to local retailers

Awful internal wiring design. Ribbon cable was by design ran to close to a fan and burned through the cable causing an electrical error. Inoperable from the first use. Was professionally installed. Will update review after contacting support.
