A:  Thank you for asking. Please contact our parts department directly with both model and serial numbers for assistance 800-621-5622 (opt 3).

A:  Granted that they are the correct wattage and length then absolutely it would be fine.

A:  No, the element needs to be the same wattage to work correctly.

A:  I think this (below), finally, is the correct answer to my question. It's even got a case # (1027887) from Rheem tech support. It took a while. Thank you for contacting Rheem.

A:  Thank you for asking. All three part numbers given are compatible, including this one.

A:  The element SP213670 is correct for a 105 gallon tank. Attached is a clip of Marathon elements. Look at the others if you want a lower watts.

A:  Thank you for asking. We would suggest contacting our parts department at 1-800-621-5622 (opt 3).

A:  Yes. These elements are color coded. Black is for the lower position and red is for the upper. Titanium is by far the best and is LD (lower density) I have had mine in for 12 years with no problems but I bought a spare set just in case as I live in the sticks.

A:  Without knowing exactly which element this is, it is difficult ti give a proper answer. It should be noted, however, that the upper element and lower element should not be interchanged.

A:  The question that was sent to me does not indicate the part number of the 4500 watt element in question. For a 50 gallon Rheem Marathon water heater, the part number for the lower 4500 watt element is SP-213670. I have attached a clip of a parts list for Rheem water heater. I hope the attachment picture turns out. Best of luck.

A:  Not quite sure what your question is. The Rheem Marathon water heater models have different wattage heating elements. 3800, 4000 and 4500 watts. It depends on what model was ordered and installed. I would guess that it depends on available electric service capacity for water heating. I ordered and installed a 50 gallon with 4500 watts because that was replacing a unit of the same capacity and wattage. I have attached a snip clip of ordering information for Rheem Marathon parts. I'm not sure if the snip clip will show correctly when you try to view it. Hope this answers the question.

A:  I installed this some time ago. It has worked flawlessly. The have been no issues whatsoever. Just be sure to keep the element regulated to a safe operating temp / wattage.

A:  When a Rheem Marathon 85 gallon water heater is purchased, there are 3 wattage models available. A 3000,3800 and 4500 watts. Whether you or your contractor opted for the 3800 watt model. There could have been a limitation for the electric service for the heater in the breaker panel.

A:  And BTW, the model number tells it all. MR-Marathon, 85-Gallons, 2-Elements, 3800-Watts i.e. MR8523800

A:  There are 3000, 3800, and 4500 watt versions of the MR85 Marathon water heaters.

A:  It appears that the length is different between the two, the length of this element itself (from the tip of it to the threaded flange) is 16.5". while the length of SP213790 is 14"

A:  The element itself is titanium , the screw in connection is brass.

A:  The rod is titanium. The fitting is brass, with plaster electrical block

A:  Contact Sun Earth for an answer to this question.

A:  Marathon heating elements will not fit into a standard water heater.
