Finally got sick of dunking my kettle in an ice bath and built a wort chiller. Thought I would share the results here.

After going back and forth I decided to build only by bending the tube and not soldering. Here is the result:


For the intake I got a short garden hose. This connects to an adapter that brings the size down. That connects to another adapter: one side is threaded and the other is shaped to grab onto a hose that is slipped on. The vinyl hose I used is sized so that it was a snug fit on that adapter as well as the 3/8" copper pipe I used (it's 1/2" outer / 3/8" inner vinyl). For the vinyl hose/copper connections I did use small hose clamps which worked really well.

The copper is 25 feet long. For the main coil I wrapped it around a paint can. Going slowly this was pretty easy. For the other bends I used a tube bender tool. This tool was not readily available in my local hardware stores--I had to go to a large car parts retailer to get one. They actually had a number of styles available and some were quite expensive. I got a mid-priced one which was only $13. Make sure it is made for the size pipe you're using and that you figure out how to use it first. I suppose inadvertently crimping the pipe could blow the whole project.

I haven't used this for brewing yet so I can't vouch for its performance. It has a single leak on one of the adapters, but I'm pretty confident that will be easily fixed with a standard sized rubber gasket.

nice bending job! remember to check the tightness of the hose clamps after running water through. The heat tends to shrink the vinyl hoses a bit and if you don't keep the clamp tight it can fly off and hit you with a blast of hot H20. . . trust me this has happened.

IMO, you also might want to replace the hose clamps on the intake side of the IC with compression fittings. That way there's far less chance of leakage. There's just too much opportunity for incoming water to get under the clamp, especially if you're running it pretty quickly through the IC. On the outflow side hose clamps work fine because the water's only flowing, well, out.
