The way this was made in the past was with a large tube with a coil inside. The wort would pass through the coil and the water would go through the large diameter tube. They quit making them because CFC's worked better because more heat gets carried away with the direct contact of fast flowing water.
I found your posts in the other thread and I've run into the same type of attitude as you in this forum so don't take it personally.
I was the "attitude" in the other thread. I knew the design was close to an "old style" shell and tube type CFC. It wasn't really though, because he had the chill fluid input/exit backwards, so there was no "counter" flow. It was a shell and tube "concur flow" chiller. I would have brought up turbulence and such, but my pointing out the lack of "counter flow" in his design wasn't even noticed until the second time I stated it.
The continued insistence that this design could somehow satisfy the OP's needs- water conservation - was what was unnecessary.
