This unit heats water No open flames to alert undesirables of activity in your location White cover blends nicely in the igloo April 18, 2015
Lots of hot water! What an improvement over our old hot water heater. Our Richmond's dip tube dissolved and never seemed to provide enough hot water, even after we replaced the tube with a new metal one. When it finally failed, we found this Whirlpool on sale - same gallons but 25% more BTU's. Family loves it. Have not run out of hot water yet - even after three people take showers. Burner seems to kick on immediately when water is used. Can't comment yet on fuel use or durability. April 17, 2015
Cheap and easy not much to say it's a water heater that going to last about 6 years I hope. April 16, 2015
This product has great features This Whirlpool hot water heater is replacing a six year rated Whirlpool Hot Water Heater after ten years of demanding service! I like the updates especially the diagnostic light . April 14, 2015
the baby2 We are pleased with our hot water heater, our prayer is that we get 17 years out of this one also. April 12, 2015
Easy to install, easy to light and fairly quite. Fair price, easy to install and light. I replace a similar unit with a 6 year warranty that was 25 years old and still working just fine. Other than I was running on borrowed time with the old one, I had to get a replacement before I was force to buy one manufactured after 16 April 2015 which probably would not fit through the door of the closet in which it was located. Not at all happy with the change in sizes! Also getting warranty replacement parts may take some time during that time you would be without hot water. Hopefully I won't need to exercise the warranty.

Trouble free operation for 10 years. Ten years ago I purchased the identical water heater and had to bring three of them home before I got one that wasn't previously damaged due to the inadequate packing. I was pleased to see that the packaging is now much more robust. Previous water heater served well for ten years and I anticipate the same from this one. The gas control knob appears rather chinzy and is definitely more difficult to read than the previous one, however. April 9, 2015
easy to install, new electronics Since i was replacing one with the exact same size, installation went very smoothly, lighting the pilot was easy, allowing for gas to get to pilot, and the light on the front is convenient, will see if it really helps or not in the future. April 8, 2015
easy to install So far so good. Installation went good , installation instruction good. Hopefully it will last as long as the last one. April 8, 2015
