I know! re-read my post, no need to remove UTH, leave it be - all you need to do is invert your tank and hot-glue the thermostat probe to the center of your UTH - OUTSIDE the tank on the bottom of the UTH (it does not have to be between the UTH and the glass). Recognize that you will likely need to set the thermostat setting up to 5 or so degrees hotter to achieve your hot spot temp.
