Just buy a 240 volt short water heater. Chances are good that someone in town has these units in stock, as they are common in manufactured and mobile homes. Maybe not the big box store, but more likely an independent (plumbing or mobile home) supply house. That way, if the unit has problems under warranty, you won't be doomed. Modifying the unit in any way usually voids your warranty.
If the big box store doesn't stock the exact model you need, find it online and have them ship it to your local store for free. If you do it online, you can track the unit, and know when it has arrived at the store for pickup. The local help is not so great at calling to let you know when the unit arrives.
