Asked by sben September 28, 20201
AnswerHello Ben, Thank you for asking, I apologize you weren't able to get the insights you required. The only deduction that I was able to come to was that the geometry of the tank would effect the efficiency of the unit. Shorter but wider unit would have more surface area in which the heat is radiating into. a Taller but thinner vessel allows the hot water to rise up away from the cold water more efficiently as there is less surface area on a horizontal plane. I hope this helps.

Can this unit be installed outside in an water heater enclosure?
Asked by tab July 20, 20202
AnswersDepending on how far north you live you may be able to install it outside but I don't think it is meant to be in subzero temperatures. You may also want to check your local housing/building codes to see if this is permitted where you live.

AnswerThank you for asking, Whale. It is possible your water heater requires a new element. Please have someone contact us at 1-866-279-4566 with a Digital Multimeter to diagnose the unit. Thank you and have a great day.
How can I control temperature of water?
Asked by Hjp April 19, 20202
AnswersThe temperature of the water in the heater is regulated by the adjustable surface mounted thermostat(s) located behind the jacket access panel(s). Dual element heaters have two thermostats. To comply with industry standards the thermostat(s) were set at 120°F before the water heater was shipped from the factory. Canadian models are set to 140°F (60°C). See page 15 of the Use and Care Manual which is a PDF file on the product page to the right of the "Product Overview"

This is the water heater model I had to have. From Magnesium to Aluminum to zinc Marathon. No one has a more potent water than what I have been dealing with. I was careful to take measurements because I knew it was going to be tight. I forgot to allow room for the thermostat covers. The plumber rotated it, so it was not a problem. I wanted this to look nice because it took a long time for me to save for this. I took out the top shelf. I glued some boards over the holes. Maybe I can buy some buy some poster board in the arts and crafts Section. I stayed with copper pipes and fittings-vertical installation. I wanted tees and pipes coming over and down. Everything is rigid and stationary so there is no lateral stress on the stub pipes. I thought it might keep the seals from leaking.
I had the plumber install a ball valve. The expansion tank was an upgrade. The inspector will be coming out soon. Rheem states that it is necessary to have a drain no more than six inches in circumference under the relief valve discharge tube. I have a drain that is larger; and it could whisk away a lot of water. It is covered up right now though. The cat’s litter box is next to it. He prefers the drain. Overall, I think the plumber did a really nice job. I will have someone build new cabinets in the future.

Gushing water 5 days before parts warranty expires (almost 6 years)
I bought and installed this new in June 2014. It is May 2020 and the water heater is gushing water from the top. These are sealed and insulated so I can't tell what is wrong. Emergency plumber is $150 an hour so I'll wait till monday to call during normal hours. Also, Rheem is closed on saturday so I can't start the claim. Was trouble free for almost 6 years. Hope it doesn't take forever to get the new one/replacement parts so the family can take a warm shower.

Professionally installed , leaky valve from day one
Just had the 50 gallon Marathon installed. I love the idea of no anode rod, eliminating the sulfur smell and nonmetallic tank. As soon as it was installed it leaked from the top valve. I knew immediately from reading reviews it was a known issue from at least back in 2016 that Rheem indicated they would look into.
I’m now stuck without a hot water heater til I can decide which to replace it with. Seems it’s the only one without the anode rod but I don’t want to take the chance replacing it from the same company. From my experience and reading reviews I wouldn’t purchase another one.

I ordered this water heater on 11-12-2018. Upon installing it, it leaked. I called Rheem in Montgomery and they authorized a warranty replacement. They said they would make an appointment with one of their approved contractors to replace it. The earliest appointment they could make was a week and a half away. The day before their contractor was supposed to come replace it, Rheem warranty services in Dover, NJ called and told me that the warranty on this water heater did not cover onsite service. They said I would have to return it to Home Depot for them to process the warranty return. The replacement apparently got dropped off the truck into the middle of the road somewhere. It's now March 2019 and I'm still waiting for my water heater.

Had to return. Box was torn open in multiple places and there was corrosion on the brass fittings. Also heater was 2 yrs 9 mos old so energy star rating was over $100 more per year than the one I purchased online. .
I had to bring it back to the store myself. I did receive a full refund though including delivery fee.

We had one of these installed to solve the sulfur smell problem with the well water. We have not had any trouble with it. It is very efficient. We had electricity go out for a week once and the water inside was still lukewarm. The tank is plastic so pay special attention to the draining instructions!
