Rated 4.6 out of 5 by 7 reviewers.
Rated 5 out of 5 by Great Water Heater Great value for the price. Works great, installation went smooth, however, it does require an electrical outlet. Great features compared to one I pulled out. Getting a rebate from The Gas Co. in Southern Calif. is a nightmare if you buy this item from Home Depot. I congratulate Home Depot for stepping up and handling my rebate and making it right for me. It took a lot of phone calls to both places but Home Depot came through when no one would listen to me from The Gas Co. who tried to tell me the sales price was an instant rebate and they wouldn't honor my application. No where on either site was the $100 off called an instant rebate but The Gas Co. insisted it was. The Assistant Mgr. at the Burbank store made it right for me and I applaud them for helping me after a week of phone call frustrations. Fight for your rebates, $100 is a lot of money to just give up receiving it. July 13, 2014
Rated 5 out of 5 by Rheem Performance Platinum 40 gal Water heater This water heater has exceeded what I had expected. My plumber didn't believe that I paid such a low price for such a high quality product. Thanks home Depot October 8, 2014
Rated 5 out of 5 by BEST energy star High Efficient water heater Replaced my old Rheem water heater...WOW...amazing how this water heater operates so quietly and trully high efficient..plus the rebate (check your local utility provider) . . HOME DEPOT you got this one right !!!! April 27, 2014
Rated 5 out of 5 by Great value! Was only $100 more than the non-EnergyStar with the 6 year tank warranty. After the $100 gas company rebate, it will cost the same with EnergyStar rating and double the warranty. One thing to note if you are replacing an older unit is that this one requires an electrical outlet. It is also a bit larger than my older 40 gal, probably due to more insulation. June 3, 2014
Rated 5 out of 5 by GREAT PURCHASE Product was available and ready for pickup at the store without issues. It's a great deal with the PGE rebate. It is slightly larger (taller & wider) than our old water heater so that is something to make note of when installing. You may need to redo some piping. Also, this water heater requires an electrical outlet - within 19 feet - for the pilot light. If you don't have an outlet nearby, select another water heater. August 12, 2014
