Our pool heater stopped working at the end of last season. We thought it would have just needed service or a cleaning as we had experienced this in the past. We decided to wait until the pool opening to be the heater looked at. We were disappointed when we were told that our heater that was Less that 5 years old needed to be replaced. Now I understand why Hayward only provides 1 year of warranty. It’s because their products is poor quality. Very disappointed in he performance.
