A friend and I are slowly setting up a nice eHERMS setup. So we setup a keggle to use for now and needed a wort chiller.
There are a bunch of how-to's on here, but figured I'd post mine with results.
I used the cheapest garden hose I could find at home depot. 25'- $15. The "how to" I read said to use the nicer hoses that supports hot water. I just used the cheapy and it works fine. The hose stays nice and cool as long as I keep the water running. Used a 3/8 OD copper tube for the middle - $15. I wrapped a small 14 or 16 gauge wire(had laying around) around the copper tube and soldered it every few inches. Getting the copper into the 5/8" hose SUCKED. I used wd-40 and soap/water.
I used a compression fitting on the ends for the 3/8" OD copper to 1/2". think they were like $3 each. I had some 1/2" copper piping and T's laying around.
Anyways, the result was about 215*F going into the setup and 70*F out. I was shocked at how well it worked!
I have about $40 into the whole setup.
Here's the how-to I used. I also added the copper wire around the copper tubing, which it doesn't have you do.
