easy install simple set up Third heater I have installed , by far the easiest to set up and get lit. Really Like the new style peizeo lighter system. Solid foam insulation much better. I can already tell big difference in the temp level maintained by the unit.. GOOD JOB !!! Whirlpool August 31, 2014
This product serves the purpose Nothing that I can find in the manual to tell me how the status light is powered. owners need to know if there is a battery for it or is it operated by the gas flow charging an internal component. August 20, 2014
easy installation Just installed today cannot say much more than it works now. July 26, 2014
It's really too early to tell: 3 days installed. So far, good. It's too early to tell about energy use, reliability, quality, etc. It was easy to install and, given it's a water heater in the garage, it looks OK. July 2, 2014
good looking heater Needed a new water heater since my Kenmore inlet and outlet nipples rusted through and were seeping water over the top or the heater. Shopped Home Depot and Hammond Lumber and finally Lowes where I found your heater and it seemed to be the best choice. I kind of liked no inlet or outlet nipples as I prefer the brass ones I used, they will not rust out. Install went well and the burner fired right up with no surprises. Performs as expected.

High Quality Product Easy to install, looks great, high quality unit, heated the water up within minutes after installation. April 24, 2014
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
