This product has great features. Very easy to install. I did it myself with the help of a friend. We were finished in less than an hour using copper pipe and shark bite connectors. About an hour later I had hot water. July 14, 2014

Great replacement water heater I bought this to replace the original A O Smith water heater in my home. Installation was easy, except I had to add a thermal expansion tank to this one. The previous water heater didn't have an expansion tank, and the instructions for this one require it. Something to keep in mind if you are replacing this and need to add an expansion tank. Directions were straightforward. The hardest part of the installation was moving the pipes in the home to match up with this new heater (it is larger than the original, so wouldn't fit in the same exact spot as the old one). However, the fact that I had to move pipes for this one does not reflect on this water heater. The warranty is great (one of the reasons I selected it). Putting it in energy conservation mode or vacation mode is as easy as pushing a button. Adjusting the temperature is also easy. I don't understand how this heater does it, but it seems to deliver the hot water to the remote fixtures faster than the old one, and the default temperature setting (120 F) was higher than the old one, so we don't need to have the hot valve on the fixtures on as high anymore. I love the digital display on this heater too. Also it has a way to connect to your home automation system or smart grid (although I am not using that feature, yet). I would definitely recommend this heater. June 23, 2014
this water heater gets water HOT , Fast , and lots of it I purchased this water heater because we had just installed a walk-in-bath and the 40 gallon we had could not do the job .It ran out of hot water before it was half full . This W.H. filled it up very fast and was so hot before it filled halfway I had to turn the temperature down.. June 22, 2014
Features a touch screen panel Standard installation. In event of touchscreen failure. Heater will still operate with touch screen removed. 12 year warranty is great. Change anode when needed and heater will last longer. June 18, 2014
Hot water heater Have not had long enough to compare energy consumption comparison, or reliability. easy to install and set up. You would think with this model /cost/ warranty it would have a brass drain valve instead of plastic! I replaced a 66 gallon A.O. Smith heater that was 10 years old, so I have upgraded the size considerably. Thus may not see lower energy bill. June 12, 2014
