CUSTOMER REVIEWS

Rated 4.7 out of 5 by 83 reviewers.
Rated 5.0 out of 5.0 by It is all we expected it to be To start with, the delivery went great. The installation was fairly easy as well. The unit is larger than our old one, but we knew that and had the room for it. If you are considering this heater,make sure you have the room as it is larger than some others. Once hooked up, it produced hot water much faster than expected based on the literature provided. We seem to have hotter water delivered faster to all parts of our house now. Don't know if the old unit was just that inefficient, but the new one is getting the credit for the performance. The unit is costly, but we were willing to accept that for the peace of mind of the lifetime warranty on the tank. As a homeowner insurance adjuster, I see ruptured water heaters every week and the damage can be devastating. This unit is also recommended by our local electrical cooperative for its efficiency...and it looks really cool for a water heater! July 23, 2013
Rated 5.0 out of 5.0 by Good Quality, Easy Install for experienced DIYer Higher price than a standard unit, however the poly tank and no anode provides us with a more reliable unit. The metal unit we replaced this with was probably within a few months of failure due to rusting bottom. The higher price should be offset by not having to replace this unit as soon as a regular metal system. One note - the measurements on the Home Depot specs do not include the preinstalled connections on the top of the unit, the shipping box however does show this measurement which is a few inches higher than on the site, (about 3"). Had measured the place to install prior to ordering and when it arrived had to rethink how to install. We used PEX and copper fittings/connections. Had my brother who has plumbing experience do the soldering. You can see from the photo how we looped the connections since the tank was taller than expected. April 14, 2013
Rated 5.0 out of 5.0 by Solid Investment We purchased a home earlier this year that offered our first experience with well water. The cold water was fine but, about two weeks after moving in, the hot water began to smell. Plumber said it was due to sulfur reacting with the anode in the one year old water heater. We tried changing the anode rod with a new one from the manufacturer. All that did was extend the amount of time between having to drain and flush the tank from two weeks to three. Options we were given were to simply cut the anode rod off. That would have caused the tank to go bad in a short period of time and, void what was left of the five year warranty. The other was to buy and add a drip chlorine system to the well pump which we did not want to do. I did a lot of research, on the causes and cures for smelly well water, and finally came across the Rheem Marathon on the Home Depot site. With no anode or metal lining it was supposed to end smelly water caused by well water reacting with the water heater. It has delivered on that promise. It’s was light weight so when it was delivered I was easily able to move it inside from where the delivery service left it. The plumbers had it installed in less than 40 minutes. There doesn’t appear to be any heat loss through the tank skin like you feel with a traditional water heater. Oh, and did I mention, no more smelly water! Even without a water issue, after having it for a few months, I’d still buy it. We’ve put a lot of money into this home already but the Rheem Marathon, without a doubt, is one of the best investments we have made. October 26, 2013
Rated 5.0 out of 5.0 by vast improvment over standard water heater The Marathon is dollar for dollar worth the extra expense. Non-metal tank and no anode translates less sediment over the years (therefore cleaner water). Lightweight but well insulated, adding both tank wrap and pipe wrap will simply save more. The curved features should add some churning action to the tank, lowering the need to flush the tank as often. Better water, lower operating costs, less maintenance. The higher price is a long term investment. March 12, 2013
Rated 5.0 out of 5.0 by Great Water Heater We've had a rotten egg odor in our water. Researching on line we found the odor was caused by the anode rod in our gas water heater. We liked the design of the Rheem Marathon electric water heater. It has a lifetime guaranteed plastic tank, with no need for a anode rod. After installing the new water heater we now have no odor. Installation was not a big job, and went smoothly. We also like the fact that the tank is well insulated, and very energy efficient. Don Titus November 18, 2014
