Great features, easy installation! Excellent, high quality, easy install, energy efficient January 28, 2015
Very Good Product Changed from a 40 gal to the Whirlpool 50 gal and am so far extremely satisfied by this water heater and looking forward to the energy savings.. January 22, 2015
Easy Install and Great Features Install was easy. Hooked everything up, filled with water and fired up the heater. Hot water in no time. January 21, 2015
Great Heater My wife and I replaced our Kenmore 50 gallon model with this whirlpool after looking extensively for a model that would save energy and not heat our house up like the model we had. So far We have noticed a distinct difference in the temperature in the laundry room where it is installed. Other than that it is a feature of our home that draws no attention. We turn on the faucet and hot water comes out until we turn it off. Even after several kids take showers there is no drop in water temperature. I had read several reviews that said there was a noise when it ran but it is quieter than our old one and unless I go into the laundry room to get something you can't hear it even though it is right next to our kitchen. If it holds up in the long run it will be an absolutely excellent addition to our home. January 11, 2015
Its a water heater Purchased at our local Lowe's and of course you have very few to choose from. The side of the box tells you what you will need to install but doesn't tell you the minimum length needed for the 2 nipples. My old ones were 1 1/2 inches and had to go back to the store a get 2 1/2 inch ones. The hot an cold are below the top about an inch.. If you buy a drip pan you will need the larger than the 24 inch due to the pilot light cover sticking out so far. January 10, 2015
Good Design Great Product and easy to install. It has a great looking design January 9, 2015
I like it I like the electronic igniter. The switch is nice to shut off when going away. I think the damper really saves a lot. January 2, 2015
This water heater's electronic ignition system seems to be more efficient. After installation, the dial of my home's gas meter seems to turn more slowly, due to the lack of a pilot light, and the burner design definitely uses less gas than my previous WH. December 28, 2014
JUNK Bought from Lowes in Sep 09 and the unit now is leaking from the bottom. It's 12/14 now. What a piece of junk. Rather buy a new one from a different brand than use the warranty for another piece of junk. December 23, 2014
Overall great unit The pipe threads were dirty and were leaking, so they required cleaning. The rubber washers in the fittings restrict flow and would have been good to know before installing. Would have been nice if it mentioned to buy an installation kit. Otherwise it looks like a nice unit and it starts up easily. December 22, 2014
