I just converted from gas to electric (induction). Will report back once I can get a couple of brews under my belt. I have two units: The small one (1,800 Watt) will heat water from tap temperature (mid-50's) to a rolling boil in about 85 minutes. Being the alpha geek I am, I took time and temperature readings along the way, did curve fitting to the scatter plot and here's the time vs. temperature curve for four gallons of water in an uninsulated, thin-walled kettle:

Using this, I know if my wort is about 150 degrees, I can expect a full boil in 45 minutes (85 mins-40 mins). Less if I simply let the wort run out into the burner on top of the cook top. My other is a 3,500 Watt unit - I haven't tested it with my large kettle.
