CUSTOMER REVIEWS

Rated 4.5 out of 5 by 89 reviewers.
Rated 1.0 out of 5.0 by Would have loved it, if it didn't leak and if HD had an overflow pan to fit ti.. Rheem provided prompt warranty service and my defective unit was accepted at HD without issue. That's the good news. This unit failed about a week into service. This is a very large anode free (plastic tank?) unit and the brass fittings to tank connections are apparently the weak link. My unit started leaking inside the outer shell where the pressure relief valve mounts to the (presumably plastic) inner tank. Unfortunately, when water cascades from the top of the unit it splashes over the bottom seam and won't all be caught by a 32" diameter drain pan (which HD doesn't sell but I found at Amazon) so water damage is a very real potential. Rheem did provide me the option to attempt repair of leaky "threaded" connection but after confirming water coming from between the shell & tank I was advised that it was not field repairable. Both Rheem & HD were very easy to deal with - unnecessarily wrestling a 105 gallon water heater about, not so much. A plastic, anode free tank is a great concept but every connection has to be bulletproof. February 16, 2015
Rated 5.0 out of 5.0 by Great Water Heater Ordered this water heater a few weeks ago. HD matched a lower price at Menards. Delivery was exactly on time, with a lift truck to drop off at my home on pallet. Surprised at how light it was. Had done a lot of research and this unit always came out on top and with a lifetime tank warranty and excellent recovery time. I used this unit to replace 2 80 gallon units that had lasted 28 years. It is well made and installation was incredibly easy- took about 20 minutes total. Had hot water in less than 20 minutes. All looks great and only hope it lasts 25 years ! Highly recommend.

Rated 1.0 out of 5.0 by Got an extra $150 for a busted heating element I read the reviews prior to purchasing this unit. I thought the people that received a new unit with a bad element in it was just a fluke.....that is until I received mine!!! We had it installed and it would not heat up. Called the company and they agreed to send a new hearing element right away. Sounds nlike it was not a big deal right? But My plumber had to reroute the plumbing back to the old waterheater until the new element arrived. Then I had to pay the plumber an additional $150 to come back and install the new element and route the plumbing back to the new heater. So that was money I wouldn't have spent but because of a bad product here we go. Of course they are not reimbursing for the additional service call. So if you plan on buying one of these.....better put an extra $150 to the side!!!! July 11, 2015
Rated 5.0 out of 5.0 by Should be the last water heater I buy. The installation was easy. I only needed to buy brass nipples and flex tubing to connect. Should last forever. The only thing that might fail is the heater element. February 18, 2014
Rated 5.0 out of 5.0 by Perfect $1200 seems a bit high for a water heater, even one this efficient. That said, I replaced a 60 gal traditional heater with this 85 gal one, in part because the only way we could fill the jacuzzi all the way was to keep the old tank at about 135 degrees, and then add cold to bring the volume up. This tank's energy guide label indicates that it uses less electricity than the old one, despite being bigger, and now I can set the temperature down to around 120, saving even more. I suspect that given the lifetime warranty, I will recover at least a good chunk of my expenditure through lower electric bills. What I really wanted was a tankless gas unit, but since I don't have gas service at this time, this heater, even at $1200, was a whole lot cheaper! Installation was simple, and because it is all plastic, once my son helped me get it in the front door, I was able to wrestle it through the house to the utility room and into place all by myself! (Of course, being 6'8" with a 7' wingspan helped!) June 21, 2015
Rated 5.0 out of 5.0 by Good looking water heater? Never thought I'd say that. I never thought I'd say there is a good looking water heater. The Marathon 85 gal. is cool looking. We call it our cryogenic tank due to its size, finish and looks. We have been using it for three weeks and so far it is perfect. It was very easy to install. You do need about 25% more space in all directions than a comparable WH. It has a large amount of insulation. The 85 gallon unit will not fit in a standard drain pan or if your old WH only has a couple inches of open space around it you will need to do some careful measuring. Don't forget the height. You could need to alter the plumbing above the WH to make room for this unit. All fittings are standard size (3/4"), male hot water, female cold water and pressure release. If you need to replace the heating element you can NOT just pick one up at the local plumbing supply store. You will need to oder one from Rheem. They range from about $50 - $90 depending on the type (Reg., SS, Titanium). No anode needed. September 4, 2011
Rated 2.0 out of 5.0 by Good Product. Upon arrival, upper heating element did not work and Home depot delivery driver dropped the water heater The water heater was very light weight and easy to install. The 85 gallon tank provide more than enough hot water for my family of 6. Be aware that upon turning the water heater on, the upper heating element did not work and had to replace it immediately. Also, the home depot delivery driver dropped our water heater. This type of service was defintely not worth the $85 we spent to have it delivered to our basement. Would recommend not using delivery service and doing it yourself. June 16, 2015
Rated 5.0 out of 5.0 by In a different league I was looking for something above the typical metal water heater that I'd have to replace again in 5 to 10 years. This bad boy has to be in a category all by itself. You can't beat 4 inches of built in insulation and non-corrosive tank/lining. So far...very pleased. July 22, 2015
