How much more is the Marathon than a conventional water heater?
The smaller Marathon units will cost approximately 2 to 3 times more than a basic steel water heater. That is not a real comparison though, as you are comparing a lifetime warranty product that is super insulated, against a 5 or 6 year warranty product with minimal insulation. Installation for the Marathon is no more and sometimes less than for steel units. Larger units such as the 85 and 105 gallon models are typically the same cost or less than short-lived steel units. Our manufacturing process is technologically advanced and very efficient so our incremental cost between our smaller tanks and our larger ones is much smaller than that of steel tanks.
