With the IC I would pull hot wort from ball valve and return up to the top with 1/2" ID silicon hose. Place hose st edge of kettle such that it would create a whirlpool. I also started to stir with spoon inside of the IC to try and help. It was faster than not having the pump, but not what I was expecting at all. The dudadiesel
plate chiller is a godsend.
As far as recirculating and BIAB, again pull from ball valve and return into camlock fitted into lid. (I don't believe in hot side aeration, and least that it doesn't affect our level of brewing).
At some point I would like to get a loc-line circle flow kit:
