Hey jgoldsney, nice to talk to you again..

Great link, Actually if you were to coild the copper tubes around a 'very thin' walled pipe that is food safe and connect the thin wall pipe to a small pump for more contact time with the coil, you have just created a very crude exchanger. The theory is that the heat from the tank water slowly pasing through the coil section will be pull out. Essentualy you are creating a simple emmersion chiller. Here is a link to a cheap home made chiller used by people that brew their own beer.
