Very easy to install Fit almost perfectly where the old water heater was, instructions were clear and very helpful. September 28, 2014
able to buy a 5 year extended warranty & made in the USA Our old water heater was manuf. in the same city and state as this one and it lasted eighteen years. We liked that it was made in the USA as our last one. Again we took out the extended warranty. September 26, 2014
Not a bad deal Replaced our old whirlpool water heater, that was originally installed in 1988. we bought the new one from Lowes, had a contractor install the new water tank. he was done in hour and half. with in an hour we had consistent hot water September 19, 2014
Good value but we shall see I purchased this water heater at Lowe's and everything seemed just fine. I am a retired plumber, so installed it myself. Everything seemed just fine but after I fired it up, a leak showed up at the pipe nipple on the hot side entering the tank. So, I will have to shut it down tomorrow and see if the problem is the thread on the nipple, or the thread inside the unit. As of now, I have no idea which it might be. Tank working great though, but this leak will have to be fixed. September 18, 2014
Came highly recommended Just installed sept 17. Hopefully it will last longer then the last one.The plumber that installed the water heater said by a whirlpool. September 17, 2014
This product was easy to install From start to finish this product was easy to install. The safety features and instructions are also written on the tank. I am looking forward to many happy years using from this product that is made in USA. September 16, 2014
Ease of installation Easy to install - pilot light is electronic and doesn't involve trying to light with matches/lighters - matched up with the height of my plumbing, very thorough instructions on how to install. September 13, 2014
