My past experience is with a 3 vessel tiered system. I am now in process building a 3 vessel single-tier HERMS system. So, I will newly have access to pumps which means I can whirlpool.
I am wondering if there is any advantage to re-circulating the wort pre-boil? My hypothesis is that it could create a more uniform temperature throughout the vessel. Without it, seems to me once the wort around the element starts to boil, it then creates a much faster "updraft" which "surprises" the probe driving the PID with boiling wort all of a sudden. By the time PID realizes what is going on you have a greater chance of boil over.
Or am I overthinking this?
