Excellent Product Installed easy, no leaks. I had warm water within a half hour and the entire tank was 120 degrees by an hour and fifteen minutes. I can't wait to try out the energy saving features. It is very quiet and looks great. Great price too. July 26, 2014
Great unit for the price Great unit for the price. Purchased from Lowes. Instructions for installation were very easy to follow and saved me from having to hire a plumber to install. July 25, 2014
You Asked The heater was dented, packaging didn't protect unit from damage. The drain valve is a plastic one, I'll replace before installing it. In general it's OK but after-all it's not a space shuttle it's just a big tube with two heaters inside and all the hoopla in the world won't change that. Is it as good or better then the one it's replacing, time will tell but the one in service now is fifteen years old and still works, I believe in being proactive so we shall see if this pans out.

Great Features I love the features this unit has on it. Good appearance and should lowers energy bill. July 5, 2014
Easy to install So far the unit has met all expectations. Just got it installed. Will know more after a period of use to evaluate the power usage. The unit was extremely easy to install and hook up and energize to start heating the water. June 30, 2014
This product filled the need for a replacement of a A.O. Smith water heater that was in the house when I purchased it 2 years ago. Seems to be the item I need as a replacement for the a.o. smith heater (24 yr old) it replaced. Hope this one will last that long. It has only been in service one day, so too early to tell.

Nice features/controls, well-constructed, great value, made in USA Unit size and weight was easily handled and positioned, installation was striaght-forward and easily achieved (read the installation instructions through first (before starting), to ensure trouble-free installation. Instructions were simple, yet thorough (one note: upon start-up,the programmable control initiates a short 8-minute self-test. With our installation, the display initially illuminated, then powered back off for the duration of the test, Be patient; the display will illuminate and function normally after the self-test has been completed. This is not clearly stated in the instructions, so be confident that the wiring connections are indeed competent and wait/allow time for the test to complete...). The heater has nice features/controls, is aesthetically pleasing, well-constructed, a great value, and made in USA. The product waranty period is 9 years. June 13, 2014
Easy installation and useage This heater was the same size as the one I replaced so this made for an easy install. Recommend using a drip pan underneath for added precaution. Also it's a good idea to connect the drip pan to a water line that leads to a source out side the basement. This water heater does not need an insulation blanket. June 12, 2014
