What would be the cheapest best way to set up an electric brew kettle for a 55 gallon stainless steel drum?Most likely 240v ,how many watts to do this fast and efficient?I don't need this all auto controlled to start off.I don't mind flipping a few switches when it gets to temp.I would like to heat mash in water in BK then heat sparge water that would be pumped into a HDPE drum for HLT.Then collect runnings back into BK for boil.Is this possible or would I need too much wattage to do this?Thanks in advance-Brewvy
