Can this model be mounted horizontally?

Asked by: Michael
No, cold water is directed to bottom of tank from inlet, part of a water heaters thermal heating design.heat rises, must be installed vertically as designed to avoid tempered down water issues

Softened Water

Hi, I have very hard water, >100 GPG hard in West Texas. My softener removes the hardness, yet will the elements in this unit not last due to no anode in the softened water? Thanks
Asked by: Stratosurfer
Yes, this unit is not designed with an anode rod. The primary purpose of the anode is to protect a steel tank from corrosion and then developing a leak. Since the interior of a Marathon is plastic an anode rod is not needed.

What is height difference between the 50 gal "tall" and the "short"?

Looking to replace countertop kitchen unit. Area available is approx. 36' by 34-35". Would like flat cover if possible because I need counter space. Would that be doable at all?
Asked by: TigerRose246
One is taller and the other is shorter

Marathon 50 Gal. Short 4500-Watt Lifetime Electric Water Heater is rated 4.5 out of 5 by 210.
Rated 1 out of 5 by from Disappointed Within 1 year it began to weep near supply connections. Before the 2nd anniversary I had to replace. Lifetime warranty is still prorated. Only received 62% refund after 23 months. Waste of time and money. I bought to avoid corrosion and it cost me dearly. From now on I am sticking to cheap and easy.
Date published: 2017-02-03
Rated 1 out of 5 by from Do not buy I have had my hot water heater for 2yrs and the heating element with out. It was difficult to find a contracted dealer who will work on it then you have to wait on Rheem to ship the part. The part is covered but not the labor so reality is you do not have a full warranty. Would not recommend Rheem
Date published: 2017-05-24
Rated 4 out of 5 by from Just a big thermos bottle Easy to install; have to take covers off to adjust temps; wish the drain valve was easier to access. Had one before but the inlet began to leak between inlet pipe and tank (a little separation occurred). Tank was fully warranted and was replaced at no cost. Tank was about 8 years old
Date published: 2017-02-14
Rated 5 out of 5 by from No smell So far it is wonderful. Hope it keeps up the great non smelly water. Well water usually ruins hot water, but this seems to really cure our problem. We waited longer than we should have. But once we put this in we have smelled or should I say not smelled our hot water.

Rated 5 out of 5 by from Two days in Seems to work fine. Unclear just how the warranty works and for how long. Do I have protection plus or what?
Date published: 2017-05-13
Rated 3 out of 5 by from Happy until recently I've been in my new house for 4 years. No problems until the past few days. Unit stopped heating.
