I got my keggle all set last weekend and now I need to make a new immersion chiller, but I wanted to know what length would be enough?
Thanks
Thanks

I dont think that's correct.shafferpilot said:As others have posted in other threads: The length is fairly inconsequential as the cooling water gets hot in the first couple feet of copper. Beyond that it doesn't have much capacity for additional heat and is just circulating through the pipe waiting to be exhausted. A five foot chiller would be just as effective while the wort is hot as a 25 footer for this reason. Some people use 50 foot of pipe and use splitters with multiple coils. That way more of the copper is cool at any one moment. In the end, soft copper pipe comes in 25 foot lengths and that is plenty so that's what people use.

Sure the water gets hot fairly quickly, but the longer it is there, the more heat it can absorb and expel. Now I realize there is a law of diminishing returns, but I think you overstated it a little about the fact that size doesn't matter(yea I know I said it).
I dont think the water in the IC get over 200 degrees in the first 5 feet.
25' for 5 gallons, 50' for 10 gallons.
I got this one abd I have only done 5 gallon batches in my keggle so far... http://www.midwestsupplies.com/products/ProdByID.aspx?ProdID=4485. I couldn't fine 50' of copper for that price so I jumped on it...looks like it's out of stock now tho.
