Very easy to install and start up. Base on a 12 year tank and parts warranty and the reasonable price of this heater, I don't perceive any problem with this great product. I chose Whirlpool water heater for first time because my previous experience with other Whirlpool home product has been nothing but exceptional. Very reliable in my case. May 15, 2015
Whirlpool 50 gallon Water Heater This product has simple diagnostic features on thermostat for trouble shooting, great design. April 14, 2015
Had to replace a Whirlpool water heater that failed early Purchased a Whirlpool water heater a few years ago and it has failed early! Went to my local Lowes and purchased the latest replacement model. Installation was a problem due to a problem with the 3/4 inch FPT on the inlet of the water heater therefore I had to remove the heater and return the unit and exchange it for a second one. Presently there is slight water leakage on the outlet side of the heater, which hopefully will have been eliminated by my last re-taping of the pipe nipple! I have never experienced such difficulty with pipe threads as on these two heaters! April 13, 2015
2nd time I bought one Bought a 40 gallon water heater in Jan. 2014...liked it so when we needed a new one for the other side of the house, we bought a 50 gallon. April 6, 2015

This product installed very easily installed very easily. heavy, need a couple of strong people to lift to stand. Lit right up and heated up water within 30 minutes. hot water for days... March 10, 2015
Very pleased with this product Installation and start up went very well. Good instructions. This unit replaces a poorly operating tankless water heater. Decided to go back to conventional water heater because any gas savings with a tankless water heater are offset by increase in water usage due to extra time lag for hot water at faucets. Wasting water in California plus high water cost made the decision to get rid of the Tankless system easy. It is interesting that one of the most mentioned positive attributes of tankless heater users is "take a shower for a long as you want". And this is true......but this practice wastes water! Perhaps running out of hot water from a conventional water heater is a good reminder that you have spend enough time in the shower. February 1, 2015
