Been a while and never really got around to a solid plan for double brew days (12 gallon batches last a while in our house since my wife is now pregnant!) but here's an idea I just thought of during last brew day:
Leave a heat exchanger hooked up in the BK during the boil, and use a temp controller on my HLT pump to recirculate the HLT water as well as maintain a boil. I have rolling boil with the PID set to 55-60% of 5500 watt power, if I ramp that up I should be able to transfer heat over to the HLT without losing a boil. I can pinch down the flow rate with a ball valve in order to maintain a boil. Just a matter of how slow is too slow?
The last couple of brews I have been maintaining a full HLT at 170 during sparge, this leaves me with some hot water at the end of the session to use for cleaning. I guess I could probably use that leftover water as strike for the first mash, and let the BK boil and heat sparge water for the hour long boil (and mash).
Anyone done something like this?
