Make sure your probe is installed properly between the UTH and enclosure.

    Yes when I clicked through the settings it was running at 100% as it usually does when the temp drops below a certain amount

    Do you have a temp gun? What does it read as the UTH surface temp? Also, do you have a thermometer on the inside floor of the tank next to the UTH? What does it read?

The power used (mines just over 1/2) on my dimmer struggles if the air drops (which it does in NY from 40 during the day to 15 at night) and the 1/2 power doesnt have enough juice to keep it up 91 during a drastic temp drop.
    I don't see the percentage power your tstat is running on?

    A dimmer is not a thermostat and the temperature of the appliance will swing with the ambient around it.

    If the appliance is 90*F with an ambient air temp of 72*F, then when the ambient temp drops down to 62*F the appliance will be around 80*F. For the appliance to stay at a steady temperature no matter what the ambient you need a thermostat. A dimmer will only work in situations where the ambient temp is constant.
