OK, in the spirit of the DIY in me, I have decided to try and make a submersible wort chiller. I have both Lowes and Home Depot near me, so I think I can do it. My thought is, and please add anything if I am wrong, 20 feet of 3/8 inch copper tubing, the kind you can bend. I couple of compression fittings to attach a couple of pieces of garden hose to and my submersible pump. My question is, do you think 20 feet of copper tubing will be enough to cool 6 gallons of wort in a 10 gallon Gas One Kettle? I have seen up to 50 feet, but I just think that is going to be way too much. Thoughts? I am off this week, so I am thinking of doing this tomorrow as I don't have much going on that I know of right now LOL. Any input is much appreciated. RR
