This company sold me a pool heater 11 months ago. The heat exchanger went out two weeks ago. They only have a one year warranty and they are refusing to cover it saying my water is bad. I had a lab report done on the water and it is perfect. I read on line that they do not cover their warranties and always come up with an excuse. And sure enough that is happening to me. My pool man said that all of the ones he has put in have gone bad within a few short years or less. He recommends Hayward now. Do not buy one of these units no matter what. Mine was a P-R407A
