What if you were to heat up the copper first in some boiling water and then using gloves, carefully uncoil it. Would that help to prevent damage to the tubing from uncoiling/recoiling?

I think the process of annealing takes a lot more heat than that and it's a good thing when you think of what we do with the coil on a regular basis. It shouldn't be bad uncoiling and recoiling just once but anything after that would probably start cracking the copper.

Oh well, guess I'll just have to be extra careful. I love excuses to buy new tools. Time to get me a torch and learn how to solder joints. I've seen it done a few times but I really should learn how to do it myself.

What is the approximate time to gravity drain a given amount of wort through the chiller? Would a 25' chiller be able to gravity drain a keggle (say 11 gallons) in sufficient time to not have to worry about taking too long to cool? I have a few projects lined up (keggle, CFC, 10 gal batches) as soon as we move into the new house.

it takes me about 45 minutes for 10 gallons but your mileage may vary.

It absolutely depends on how high your kettle is. Higher means faster flow.

Good point Bobby, I guess if the ID is limiting the amount of liquid that can travel through the chiller that increaseing pressure (static head) will increase flow. Water towers are tall for a reason.

I guess my only question is I have done the math and this will cost 60 dollars minimum to build.

You can go on eBay and get a plate chiller for 59 dollars................

for me I only do projects like this if it's going to save me money.

It all depends on where you get your copper from... I bought my copper tubing in bulk, and then sold 3 CFC's here on the classifieds.

Yeah but the soft copper is going to cost 30 dollars for 25' then the high temp hose is another 30-35 dollars.

Then add the silver solder and fittings and this is not really worth the time and effort to build.
