HaywardW3H135FDN H-Series Pool/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. 🤷‍♂️

Easy install.

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

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

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!

No customer service, bought this heater and it worked for 2 days before getting a SF code, book says it the thermistor, can't get any help from hayward! Sent several emails, phone calls. Called Watsons pool who is on the " recommended " list for warranty work, they don't work on it, HEYWARD please answer my emails, just send me a thermistor I will install myself and send the defective one back

Ran water through it for 2 months. Maybe on 10 times. Got a leak at a weld. At the time the tech came out my ph was low. Had to change my hose and chlorinator, pump didn’t run for a couple of days. Low ph was my fault and the reason why the weld failed.
