Nice features Installation was a breeze. I would recommend this to a friend. April 2, 2014
So far so good Replaced 25yr old water heater with this one. Fit right into same hookups. Simple to ignite. Keeps up with three adults in household. March 15, 2014
Nice Features..... This Whirlpool water heater appears to be a quality-made product; the new monitored gas valve is a plus, to check pilot light operation at a glance. Hopefully, it will outlast the last Whirlpool water heater I replaced..... February 26, 2014
Good product Whirlpool Have not yet put it to use as it was just installed but have every confidence that it will be fine. Last hot water heater was 21 years old. This is a good company so have high hopes it will be equally as good for us. February 1, 2014
easy install So far so good, had an easy time installing and starting up this water heater. The time it took to fill and heat was fast, but I had to set between c and hi to have water as hot as needed for baths and dishes, also since my water heater is installed in our basement which happens to be a little on the colder side, we purchased a insulated tank wrap that was very easy to apply around the tank, this should help with overall cost to use.

Watch For damaged units Needed a short 40 Gal. LP heater ASAP. Not a popular item at other stores so I Purchased @lowes. Selected box that was not damaged and when I opened the unit was flattened on top and bottom of unit. Returned and when I installed replacement unit, relief valve constantly leaked. Found out valve was damaged due to handling at store. Required another trip for replacement valve. Did get a discount but not worth the time lost going back twice. Makes hot water but is much louder than my old one. I dont have a great feeling about my purchase. October 27, 2013
electronics are good for what i paid for it at Lowe's very nice product October 24, 2013
Easy Install This is replacement unit for a 6 year old Whirlpool unit, very satisfied with previous unit and this unit has improvements so I am sure it will be a better unit. Installation was easy and new control makes for easier lighting of pilot light without standing on my head. September 21, 2013
The best feature !!! Hello, I believe the best feature is how quite this water heater is to the others we have had. As we have only had this Whirlpool model for only a couple months now we love it, very quite and is saving us money already. Thanks Whirlpool September 17, 2013
excellent for early time in use in the short time of use, the heater did not have to start heating when hot water was used. It appears to retain the hot water very well and not require the burner to activate on medium usuage.. August 10, 2013
