I was thinking of taking the Letina M730 mixing tank and adding an immersion element. Plan was to add hot water form a tankless water heater then raising the temp to 180dg for the corn (bourbon mash bill). Would the motor hold up ? Would the element be remotely efficient? Trying to create something for around $4,000 and all electric.
