It is possible to burn/scorch you wort with an electric element--I've managed to do it twice. Once with an attempt to do a 90 min boil, had the PID set at 85%.-probably too high, but didn't get burnt until it was over 60 min into the boil.
The 2nd time was last night while making a pumpkin ale---added the pumpkin to the boil, and about 1/2 hour later a nasty burnt smell. (I added the pumpkin with 30 min left to go in the boil) PID was set at 75% max (its a 5500 watt low density water heater element)
The system is a keggle with 5500 watt element, PID control and thermocouple.
