I am trying to get all of the parts together for an all electric system and I am just trying to figure out how many gallons I can boil with a single 5500 watt 240 V element. I just have a single 30 amp circuit available so much bigger is out of the question but I am trying to decide between mounting it in a 15 gallon boil pot for 10 gallon batches or if I could possible make a 15 gallon batch happen with just that element.
