Rated 4.7 out of 5 by 291 reviewers.
Rated 5.0 out of 5.0 by Very pleased with my Rheem Hot Water Heater! First of all, it is well insulated. When it is heating water, I can place my hand anywhere on the water heater (not on the vent) and it feels cool to the touch! Love the extra thick pipe insulation provided with water heater. (See picture showing the top of the WH) Second, the value. Other stores didn't come close to the pricing of The Home Depot. They were selling the exact same water heater for $100 more. Third, the performance. The recovery time of this unit provides plenty of hot water for a family of five, including three teenagers, top-loading washing machine, dishwasher, etc. Also added a drain pan (see photo of lower portion of water heater) July 29, 2014
Rated 5.0 out of 5.0 by Thumbs up for Rheem I am replacing a Rheem that lasted 23 years, so buying a second Rheem was a no-brainer. This new one is more efficient, heats the water faster, maintains temperature better, and looks great with the grey finish. Installation was a snap using SharkBite connectors and a flex gas line.

Rated 5.0 out of 5.0 by Provides hot water like it is supposed to I was replacing a similar 40 gal 40,000 BTU 9 year warranty Rheem water heater and it went just as expected. The height of the old one was a little shorter, but I decided to use PEX tubing to connect the supply and output sides of the water lines and so glad I did. Made the job a million times easier. The old galvanized piping was at least 30% clogged after just 11 years of use. Brass fittings meant no dielectric corrosion problems and I added a shut off valve on both sides of the water heater so I don't have to drain all the hot water pipes again when the next water heater has to be installed...many years from now. The installation was straight forward. I reused the gas pipe from the old water heater and 3 connections later everything was running. I figured 3 hours for installation and that is how long it took. Getting some of the old pipe loose was the toughest part of the project. The piezo ignition made lighting it a breeze. The LED indicator makes knowing it is lit a cinch and I had hot water 1 hour later. April 6, 2014
Rated 5.0 out of 5.0 by Follow The Reviews! I would liked to have spent less on a hot water heater, but the reviews on the less expensive did not come close to these reviews. I did my home work, and got ready to replace the old hot water heater the next time it went out. Cold shower this morning, Home Depot this afternoon, and a hot shower tonight before bed. Went in just like the previous reviews. If you have a two wheeler, two hands, and four hours, this is the one to go with, There's only three connections, hot cold and gas. Get some pipe dope, and go for it. I'm 75, and if I can do it by myself, I am sure you can too. September 6, 2014
Rated 1.0 out of 5.0 by Rheem worst customer service ever encountered. Water heater burner failed 1 week short of 2 year parts and labor warranty expiration. Was within the period however rheem customer service insists upon using the date of manufacture as warranty commencement date not the date the installer purchased and installed it. Felt like I was in the twilight zone in speaking to their service center. Horrible customer service, would never purchase another rheem product in my lifetime. October 14, 2014
