I'm working on upgrading my current 10 gallon setup to 20. I use keggles and a 5500w element in my HLT and 4500w element in my BK. The new kettles will be 30 gallon for 20 gallon batches.
Should I be using two elements for both the HLT and BK?
My 55 gallon kettle will boil 45 gallons with 2 4500watt element. I use 3 elements to get it there quckly, then switch to 2 for a nice even boil.
You will appreciate having two 4500 watt elements in both vessels.
