I made a copper coil IC, that was slow. Then I made another one and used one as a prechiller in an ice bath, that didn’t work either. I ran both of them as ICs in the kettle, still slow. I added a shirron, not fast enough. I ran through the shirron first and then the water out went through both of the ICs in the kettle, better but still really inefficient. I got a therminator, now we’re getting somewhere. I added a 12 dollar submersible fountain pump in an ice bath and about 6 dollars worth of fittings, now I can get boiling wort down to 68 degrees in 5 minutes.
If you live in the southern US, do not waste any time or money on trying out cheap chilling solutions. Buy a therminator (haven’t tried dudadiesel so maybe they’re fine but shirron is not, too restrictive and poorly designed for a gravity feed) and a cheap pump for an ice bath circulator. This 250 is much less than the 500 I have spent to end up at the same place. On a different note, anyone want a shirron?
