Quantity:

The MR75245 Rheem Marathon water heater with a tank capacity of 75 gallons is a good choice for installations in homes with 3+ bathrooms or more than 4 family members. The MR75245 Marathon water heater can deliver on average 78 gallons of hot water per hour (first hour rating).

Marathon water heaters are considered to be the best electric water heaters on the market. Marathon heaters carry a limited lifetime warranty against water heater leaks. All Rheem Marathon water heaters have a high efficiency design with a lightweight tank that cannot rust through or corrode. Marathon heaters are stronger and higher quality by virtue of being built without using steel or other metals.  Rheem Marathon water heaters are made of cross-fiber polybutene. This material is ten times stronger than steel. Cold water heavily infused with minerals cannot damage this water heater tank’s strength. As a result Marathon water heaters last much longer than electric water heaters made of steel.

Marathon water heaters are built with one fused upper heating element made of copper to help protect against dry firing. The Marathon 75 gallon electric water heater’s (MR75245) lower heating element is made of titanium to provide resistance against lime and sediment build up. While slightly smaller, the MR75245 Marathon water heaters can make a good replacement for standard 80 gallon electric water heaters.

Be aware that GP Conservation also stocks 85 gallon Rheem Marathon water heaters (MR85245), which can deliver up to 91 gallons of hot water per hour (first hour rating). The MR85245 should also be a considered when replacing 80 gallon electric water heaters.

Features:

• Seemless, 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.

Energy Savings:

The 75 gallon Rheem Marathon water heater (MR75245) is unrivaled in its energy savings. All Rheem Marathon water heaters use electric immersion water heater elements which transfer 100% of their energy into heating the water. Rheem Marathon water heaters significantly reduce heat losses by insulating the water heater tank with Polyurethane Envirofoam. The use of Envirofoam traps the heat inside the tank and keeps the water hotter for longer periods of time without the elements cycling on and off to re-heat the water.

Standard electric water heaters suffer from high standby losses; up to 20% of the energy used in old standard electric water heaters is to compensate for heat loss. This is not the case for Rheem Marathon water heaters due to the Envirofoam insulated tank. Replacing a standard electric water heater with a Rheem Marathon water heater can result in significant savings on the home owner’s electric utility bills over the course of a year.
