So what would everyone recommend? I would use the immersion chiller to knock it down, then I have 2 options:
1) A pre-chiller (25' coil) in an ice bucket, inlet from the hose, outlet to the immersion chiller. Immersion chiller output to the sink drain
2) a pond pump, immersed in ice water. Outlet to the immersion chiller. Immersion chiller output back into the bucket to recirculation
Obviously option 2 saves more water, as it would eventually lead to a reusable amount of water. I think I may be able to swing either option for about the same price, and I have a big freezer to make a bunch of ice. Would option 1 work a lot better? If not, it sounds like option 2 would be better because I can reuse water. But if option 1 is a ton better, I would go that route. Thoughts?
