I'm no expert
, but I have done several 15 gallon batches, 18 gallon boil using two 20amp, 120v circuits w/ 2 elements at 2000w each, or 4000w total. I'm thinking about running 240v into my basement, but I already have 5, 20 amp, 120v circuits down there and haven't really ever felt short of power using 120v. Yes with only 4000w total, it does take close to an hour to go from sparge temp to boil...but that is w/ about 18 gallons
in a 20 gallon kettle.
Perhaps it makes more sense to refer to total watts required rather than voltage...roughly 2-3000 watts will work for five gallon batches, and 4000 watts will work for 10 gallon batches.
