good Always had good service with whirlpool appalince's January 28, 2015
I like the diagnostics on the burner control. The heater is a very good value for the price. I have a friend that purchased this model two years ago. He told me how, when he had trouble with his gas controller, you sent a replacement to his house that arrived the next day. That is really impressive warranty service. January 27, 2015
Easy to install. Problem with cold water inlet threads The water heater was easy to install. I did have a problem with the female threads on the cold water inlet to the water heater. There was some metal in the threads and I needed to chase the threads to allow the nipple to thread into the water heater. Other than that the quality seems good. January 26, 2015

easy to light i love the ease of using the pilot light i can even do it myself being a woman, it was so easy to follow directions to light it January 12, 2015
nice product looks and installs like most water heaters. I really like the newer gas valve. Makes it easy to know if the pilot light is on and I hope to never use the light for trouble shooting. but nice to have it, if something does go wrong. January 10, 2015
