Sorry to resurrect an old thread, but I was wondering if you could essentially use an immersion chiller backwards? I live in an apartment that, unfortunately, doesn't have any faucets that were made within the last 30 years. I'm pretty sure I wouldn't have a way of hooking up to the faucet without MAJOR leakage problems. Could I run the hot wort (2.5gal batches) out of the kettle, through a copper coil in a sink full of ice water? It just seems quicker than dropping the kettle itself in an ice bath.
