For recirc on the wort, wouldn't that stir up the break material? Or do you plan for that falling through the false bottom or something? I've considered the following modification of my setup for better and more environmentally-friendly cooling:
IC goes into wort, ice water is circulated via pond/aquarium pump through IC and then through the water cooling portion of a plate chiller. second pump pushes wort through the plate chiller and recircs into the kettle.
This seems like a much better option than what I'm currently using, which is basically wasting a ton of water.
