If I ran 2 cables from separate circuits in the house and put together a box with 2 single GFCI outlets that I could put switches on, maybe that will work?
But what elements are best to boil 7 gallons?
I boil 6 gallons with a 1650 watt element + my stove top. I run both full on until I reach boil then I turn the stove eye down to 2 or 3 to maintain a good rolling boil. I tried turning the stove eye off to see what happens and my batch drops down to a slow boil, probably still more than fast enough but I like a full rolling boil.
So, in your case you might want to install two 2000 watt elements to be safe. But if I were going to go all 120V electric & not convert to 240V electric I would go with two 1650 watt elements, one plugged straight into the wall and the other through some sort of controller. This would give me maximum control over my boil.
