I only used 20' of copper tubing and am now thinking I should have gone bigger. I'm planning on using it with my 8 gallon aluminum pot (full boils). Am I right?
It will work...but not as fast as one with more length of copper. It is an easy fix however if you want to make it longer. A coupler...some solder and viola.
I have a 25 foot one and works great for 5 gallon batches... Like above make sure to stir...my wort goes from too hot to touch coming out of the chiller to cold and then when I stir back to too hot...
