Went to the big box today to pick up some copper tubing for an immersion chiller. They carry type "L" and refrigeration tubing with the "L" being stiffer and much more money. Also Lowes sells it in 20 ft lengths of 3/8.
Is the less costly refrigeration tubing ok and is 20ft long enough? Would 20ft of 1/2 be better?
I will be using a 30qt turkey fryer pot.

Type L is a thicker wall guage but the refrigeration tubing would probably be easier to form. 20ft is probably not be enough length. The 1/2 inch diameter would give more surface area and flow to cool quicker.
I think I will do the 20 ft of 1/2 and use standard pipe for the risers and this should give me a full 20 ft in the pot.
Doing my first all grain this week and i am trying to be fully prepared.
