Convinced me to move to induction. I bought an Avantco IC3500W induction cooktop and it heats up 6.5 gallons of water faster than my propane patio burner. Now I don't have to go outside to brew!
Your statement is correct, but I happen to work in the building automation controls field, so I have a programmable logic controller with a PID modulating the VDC signal.
I found this device by asking the sales rep a few questions. Plan on ordering and was hoping someone else might have used previously.
