Reviews helped with purchase After reviewing Rheem, GE and others I found the Whirlpool had the best ratings and value for the money. I replaced a 10 year old AOSmith that failed just out of warranty. It was easy to install and only took about and hour or so. I recommend this product. December 15, 2014
This is a great product with wonderful features. Installation was simple and striaght forward. I really like the heater controls on this unit. December 13, 2014
suggestion Everything is good except one point. The black knob to set the temperature is hard to see. You need a white mark on the knob in order to see the position in a closet. December 12, 2014
Great Value Got a 9 year warranty on a 50 gal gas water heater for under $500. Went through Lowe's and got same day install for $275. Water heater works good! Got it set on the lowest heat setting, and the water is plenty hot. Like the controls on the front, easy to use. December 11, 2014

WhatI needed Too early at this time to tell what this heater will do. I am sure, so far, that it will be more than I hoped. I had to get the 50 gal because of the use. November 26, 2014
djh Retroactive. The product that has been pretty good in the past. It should be pretty good in the future. I continue to hope that it is still a good product. November 24, 2014
