Making an immersion chiller out of scrap copper tubing I have dug up around the house. I have about 30' of 1/2"id and about 30' of 1/4"id. I am going to run tap water through the 1st coil in an ice bath and into the second coil that will be immersed in the wort. But here's the question. Which one do I use for the ice bath and which for the wort.
My initial inclination was to go big to little just based on flow (i.e. I didn't think the smaller diameter line could "fill" the larger diameter line very well). But when I lay it out that way, I'm just thinking that I'm sacrificing all of that potential volume that could be in the wort.
So what does everyone think? Big line in the ice and little line in the wort, or vice versa? Thanks!
