Rheem Marathon Solar Water Heaters

matt_sunwaysolar Member Posts: 61
Does anyone have any experience (positive or negative) with the Rheem Marathon line of solar water heaters?

They seem to be a pretty good deal, including the lifetime residential warranty, the high insulation value and the lack of anode rods. Price looks pretty good too.

Looking specifically at the MTS105345 and MTS85345 (Specs attached).

Any help is appreciated.

    I have had one running for 10 years with no problems. Qualified for a local utility rebate on the tank alone.
