a good product simple and easy to install and match my old product May 18, 2015
very good purchase n easy install DIY This was a very good purchase n easy install DIY for a first timer. No issue found in last 90 days. May 16, 2015
Respect for Whirpool products diminished. The unit being registered this date (5/12/15, installed 5/11/15) is a replacement unit for a Whirlpool water heater purchased/installed in late October, 2011 (3 years, 6.5 months)! The reason for the severely shortened replacement timeframe is that the water heater replaced began leaking and filling the drip pan. There was almost a full bucket of water in the pan when we heard the water leaking. I am grateful that these units have a 9 year warranty but I am highly disappointed that the short amount of time noted above would allow this water heater to have the issue also noted herein.

Easy to install & easy to operate Installed this new basic water heater myself three days ago. Bought this water heater to replace another brand that didn't last through its limited warranty. The Whirlpool water heater was easy to install, BUT you do need to buy dielectric heat trap nipples for installation - they do not come with the water heater. Lighting the pilot was very easy - the easiest of any water heater I've owned in my life because there is a flashing light that indicates its on. The burner in this water heater is louder than my old water heater. In a quiet house, I could hear the burner in my dining room which is not above the water heater in the basement. Overall, it was easy to install and operate. As for recommended maintenance, I don't think anybody is going to remove the rod and inspect it at six months or anytime afterward. They should figure out a way to handle corrosion differently. May 5, 2015
This product combined price and quality I purchased this product because in combined price and quality, was manufactured in USA, and was easy to install April 28, 2015
Easy to install In replacing an old heater I only had to get one inch longer pipe nipples on top of the heater and a 1 1/2 inch longer extension nipple on the gas pipe and it fit exactly where my old one was. That all was a big plus. Initial igniting was simple and easy. No electricity needed for heater to function. April 26, 2015
Replacement A very straightforward product. Very little modification to existing piping needed. Accompanying information easy to understand. April 22, 2015
Great Product Another great Whirlpool product added to our home. When our hot water heater was going, there was only one name brand I looked at. As with our other appliances from Whirlpool, this one was a great value and easy to install/hook up. The installation took no time at all, and the manual was easy to read and understand. The pilot lighting instructions were easy to start and the LED status indicator is a great option to have to understand your water heater status. I like the tall thin profile of this unit and sits better in the space than my prior heater. All around a great product and so very happy with Whirlpool! April 7, 2015
Good overall The only problem was during initial instillation no mention on the carton showed I needed nipples for tank to supple lines cost me an extra trip to home center. April 6, 2015
Nice unit Quiet, delivers what is expected. No issues, hope it lasts. April 5, 2015
