Great Water Heater with Simple Controls Overall I am happy with this water heater. I like the controls, they are easy to work with and there is a vacation button to save energy while you are away. It would be good if you could program in the number of days you will be away so the water heater will come out of vacation mode automatically. I would like to have had longer pipe nipples on the inlet and outlet so you don't have to scratch the paint off the top of the water heater when you turn the wrench on the mating fittings.

So far so good I installed this unit today very quickly and efficiently. Within minutes of hooking it up, I had hot water coming out of the faucet. May 20, 2015
This product looks great. I really like the electronic features. Unit looks great, many good features to conserve energy. The installer said he really likes this unit, thought it to be one of the best on the market May 20, 2015
Replacing an inefficient 80 gallon unit after 11 years Researched many options to replace my current 80 gallon unit, and selected this 50 gallon - 12 year model. Online reviews are extremely positive, and anxiously awaiting the ease of operation and efficiency of this new unit. The energy factor of 0.93 actually qualified me for a $100.00 rebate from my electric co op. May 19, 2015
Very good water heater, easily installed Read instructions very carefully. The initial system diagnostics is very important. Drain valve and drain pan don't work out too good, you need to raise the heater about 2 inches higher than the pan. I used treated lumber to build a solid support between the heater and the pan. This allows easy access to the drain valve. This is my third Whirlpool Heater, and I like them very much. May 19, 2015
Nice Overall performance is great. Was easy to install, easy program,heated up quickly and has great recovery. Looks good also. May 17, 2015
Installation was a breeze! I replaced a Whirlpool water heater with this one. The one I replaced lasted 12 years. I'm hoping for a similar lifespan with this one. May 14, 2015
I was impressed with quality of product. Well worth the price. The quality of this heater is excellent, and the ease of installation was impressive. I had hot water in about one hour. We have plenty of hot water for a family of 4. I highly recommend this hot water heater. May 14, 2015
