Great looking water heater Easy to install, great looking, woeked fine. Easy to use controls. I am writing this review on 7/12/2015. This not quite 2 years after purchase/installation. The water heater worked flawlessly up until now. It is leaking water from the bottom. July 12, 2015
Excellent Installation was very easy. Also, the features were easy to use . Just started using so I have no idea if it will lower my energy bill. June 11, 2015
Good price with good features Although I did not install the water heater, the plumber did it in no time. I like the digital screen, easy to use and accurate. Is too early to know if the energy saving features will result in actual lower energy consumption. July 21, 2015
Only had for a week but so far it has been great. As stated above, only had for a week but so far it has been great. We replace our old Whirlpool the this new one, we had good results with the old one until one of the elements went out, now we have upgraded our water heater this time and hope we will get the same results as with the one before it. We do like the digital display on the front which makes it easier to make changes or monitor what is going on. July 19, 2015
This is a replacement for what we had previously. This is the same as what we bought 11 1/2 years ago. The same brand and type. It was excellent. When it went out, we bought the same brand and gallon sized-energy saver as we bought way back then. It was excellent then. We expect this to be just as excellent.. July 19, 2015
Tank bigger then replaced unit. Both 40 Gallons. SIZE Because of larger size installer had to install longer wires and alter plumbing. July 18, 2015
This product has great features easy installation, great value. instructions very user friendly. July 12, 2015
This product does have good features. This product is replacing an 80 gallon heater and so far I can't tell any difference in recovery for hot water when I am washing clothes, dishes and taking a shower--all at the same time. May 16, 2015
Quality product It's larger than one being replaced This is the first time I've ever purchased a water heater. Whirlpool is a reputable brand and I'm confident this waterheater will give many years of quality service. June 29, 2015
This product is easy to install. The only problem was the pressure relief valve was turned past vertical by several degrees, making it necessary to add extra fittings to get it lined up to the drain. I figured taking it out and redoing it would void the warranty, It makes for a sloppy looking installation though. May 13, 2015
