Rheem offers a 50 gallon Marathon water heater with a low profile water heater tank (MSR50245). The MSR50245 Marathon water heater is considered short due to its 47 1/4 inch height and 28 1/4 inch diameter. The Marathon water heater model MSR50245 is 19 1/2 inches shorter and 4 3/4 inches wider than the conventional 50 gallon Rheem Marathon water heater (MR50245). The difference in physical dimensions allows the short water heater to suit applications where standard tall Rheem Marathon water heaters would not fit.
Rheem Marathon water heaters remain the best electric water heaters on the market today. Rheem Marathon water heaters feature a unique, lightweight and highly efficient design with a tank that will not corrode. These electric water heaters have a residential limited lifetime warranty that sets them apart from any other electric water heaters. Marathon water heaters are much stronger and higher quality electric water heaters that in most cases last significantly longer than electric water heaters made of steel. The durability of Marathon water heaters is a result of their unique non-metallic tanks made of extremely strong cross-fiber polybutene.
Marathon water heaters come with one fused upper heating element to help protect against dry firing. Compared to other short water heaters, this short 50 gallon Marathon water heater (MSR50245) also comes with a lower heating element that is made of titanium to help provide better resistance against lime and sediment build up. This 50 gallon water heater made by Rheem Marathon is a great long lasting electric water heater replacement for other short water heaters or applications where a standard electric water heater will not fit.
- Seamless, blow-molded, polybutene tank impervious to rust and corrosion.
- Multiple layers of filament wound fiberglass to give tank extra strength.
- A recessed drain valve so it's out of the way of brooms and scrubbers.
- Tough molded polyethylene outer shell to resist against dents and scratches.
- High temperature polysulfone dip tube.
- Factory installed conduit between element control boxes.
- All plastic tank eliminating the need for an anode rod.
The short 50 gallon Rheem Marathon water heater (MSR50245) provides significant energy savings compared to old short electric water heaters on the market. Rheem Marathon water heaters significantly reduce heat losses because of the use of advanced Polyurethane Envirofoam insulation filled tank shells. The insulation reduces heat losses by trapping the heat inside the tank and keeping the water hotter for longer periods of time without the elements turning on and off to reheat the water. Rheem Marathon water heaters use electric immersion water heater elements which transfer 100% of the energy used into heating the water.
Replacing standard electric water heaters with Marathon water heaters can account for significant savings on the home owner’s electric bills. Standard electric water heaters suffer from high standby losses; up to 20% of the energy consumed in old standard electric water heaters is used to make up for heat losses. This is not the case for Marathon electric water heaters because of the Envirofoam insulated tanks. Over the course of a year this can account for significant savings on the home owner’s electric bills.
