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. 🤷‍♂️

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!!!

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.

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
