So far so good. Just installed. Just installed, but so far so good. Product has a nice appearance and seems to operate fairly quiet. Not too difficult to install, had to modify gas line and plumbing a bit, but it was replacing a 14 year old tank. Pilot light took 3 attempts to light, but had to purge air from gas line.

This water heater has all +++s Design is good ,,Installation was mostly good ..except for overflow was far other side from average water heaters little more piping and time....I have mostly all whirlpool appliances and they last for years . Also on this unit It flashes lights all the time but nowhere can I find a battery nor does it say in the book. If it ever stops ??? Still Super Water Heater. Wrote this after 10 months of use All ++++s August 12, 2014
Awesome product for the price & value My house is about 8 years old with 2 water heaters installed. The first one went bad 2 years ago, and I replaced with Whirlpool 40G (9-Year warranty). The installation process was too easy and it works great. The 2nd one went bad last month and I replaced with a similar one. I am fully satisfied with this quality product. August 3, 2014
Price was good! Price was good and didn't take long for it to heat up! and easy to use! August 2, 2014
Good design and easy to install The installation was straightforward and took about 1 hour. Of course, I had the required fittings and connections before starting the install. The heater is simple to set up and use. The only problem I had is the heater is installed in a closet in the garage with the HVAC unit. Space was very tight and hindered removal of the old heater as well as install of the new one. July 28, 2014
REASONABLE PRICE WITH A 9 YEAR WARWNTEE RELATIVELY EASY TO INSTALL THE ONLY PROBLEM I ENCOUNTERED WAS A PIECE OF WELDING SLAG ON THE INLET FITTIG THAT HAD TO KNOCK OFF THE REST WAS SMOOTH .FIRED RIGHT UP July 21, 2014
whirlpool makes good products im never disapointed with the whirlpool products that i buy. my only ADVICE is you need to put needed components to install list <on the outside of the box>. so you dont go home and then find you have to make another trip out. frustrating....but....easy fix. thx.
