Stainless steel water storage tank that is not only durable but eliminates the need for the anode rod and all the issues that are associated with this sacrificial element; corrosion, hydrogen sulfide gas, development of bacteria and rotten egg odor, even the scale build up.
Heavy-duty insulation retains the heat inside the unit longer resulting in more savings.
Lightweight design allows easy handling.
Good tank capacity of little over 50 gallons (52 gallons to be exact) provides enough hot water for a family of 4-5 and supplies one to two bath homes.

The water connections are located at the top of the unit for easy installation.
The model provides long draws of hot water, first-hour delivery is around 84 GPH - highest on this list.

Rheem - Marathon MSR50245 review

Marathon

Rheem / Ruud Marathon MSR50245 (sold on amazon.com) is the only 50-gallon electric water heater that is made of the long-lasting plastic material and has one of the longest warranties:

Rheem provides a limited lifetime warranty.
Six years warranty for replacement parts.
The upper heating element is protected against "dry-firing", and the lower element is made of stainless steel for longer life.
Seamless, blow-molded and lightweight polybutene tank that doesn't leak.
High efficiency (energy factor is 0.94), losses only 5 F of heat in 24 h.
First-hour delivery is 61 GPH, the recovery rate is 20 GPH.
As the Marathon doesn't have the metal tank, the anode rod is not needed, resulting in less maintenance involved and an absence of the hydrogen gases and rotten egg odor.
No rust, no corrosion due to the non-metallic water tank.
One of the most durable tank-type heaters in the water heating industry.
Bowl shaped bottom allows complete draining.

The water heater has mostly good reviews. The customers are happy to have a unit that won't corrode and leak, or be exposed to unpleasant sulfur smell and issues that come with the deteriorated anode rod. The handling was easy due to the water heater's lightweight design.

The homeowners didn't like the higher price of slightly over $1000.

Rheem / Ruud Marathon MSR50245 is due to its high-quality tank, great energy factor EF and a lifetime warranty, many great reviews and great service network from the well-established company, probably the best 50-gallon electric water heater to buy on the market.
