Rated 5.0 out of 5.0 by Bruno This product is everything I expected so far.
The delivery was excellent, on time and without any issues.
Installing the heater was extremelly simple. I used Sharbyte connectors and the whole installation was done in less than 30 minutes. I am still surprised how easy this was to do.
So far the water temperature is great.

Rated 5.0 out of 5.0 by Martin Excellent water heater, better than any I have owned
We have had several water heaters in the past few years, living in the country the well water was hard on the other heaters. We tried a Marathon, upon advice from one of our new neighbors, and have not had one minute of trouble since then, just reliable hot water when we need it. We are going to replace our dairy barn water heaters with the larger Marathon units right after January 2012. Our local plumber also told us he has had almost zero problems with the Marathons and that the ones that had problems were due to being installed by someone who did not know what they were doing.

Rated 5.0 out of 5.0 by DRDAVE I would not use any other type of water heater!!!
I purchased this water heater because it is the only water heater on the market that does not put aluminum into the water. All other water heaters have a warning not to drink the water from a hot water heater because they contain an aluminum anode that adds poisonous aluminum salts into the water and are not safe to drink. Check out the other hot water sites, they say right in their web sites "do not drink the water from their hot water heaters" it is for washing and bathing only. This water heater produces safe clean hot water.

Rated 5.0 out of 5.0 by Stephanie So happy with this hot water heater
The Marathon is so quick and efficient! I never wait for hot water or run out. It was easy to install and given the energy rating I'm hoping to save a lot just not having to rely on oil anymore.

Rated 5.0 out of 5.0 by Granturismo Excellent water heater!
I live in a condominium and when it was time to replace my aging water heater, I wanted to get something that would last. The Marathon unit in a 40 gallon size was larger than the 50 gallon unit it replaced, and barely fit into the master closet where it had to be installed. Despite the overall size, the unit is quite light when empty, and easy to maneuver into place. It was installed in October of 2012, and has worked flawlessly since. The quality seems very high, and I definitely recommend this water heater. Now I don't have to worry about the tank leaking and damaging other units in my building.

Rated 4.0 out of 5.0 by Self First one leaked, Home Depot provided warranty replacement
Marathon heater developed slow internal leak after two months. Home Deport arranged warranty replacement through Rheem. Employee (Amy) even delivered replacement in her personal vehicle and on her lunch hour. Hope this one meets expecations. Home Depot customer service could not have been better.

Rated 5.0 out of 5.0 by Vanguard Very well designed
Living in an upper condo, I wanted peace of mind from leaks as well as efficiency. This unit gives both. The delay between turning on the tap and having hot water is reduced to almost nothing so I waste much less water. Recharge time is fast. Very nice unit. Easy to install and no need to wrap because it's already insulated.

Rated 5.0 out of 5.0 by DBPLS This product is a great value and has a great warranty.
This is our second Marathon Water Heater, the first one was so great that when our second conventional heater went out we did not even look around, we bought the another Marathon.
