Default My DIY stainless IC

So my father lucked into a spool of flexible gas line by happy accident. It's ribbed stainless with a yellow plastic wrapper, 3/8" ID, and all of .010" thick. It doesn't hold a wide bend very well since it is so thin, so I had to use copper wire to tie it to itself as I wrapped it. It's 1/2" OD, so I used some 1/2" ID vinyl for the supply line with a bard fitting and hose bib. I went short on the tubing, so the output line isn't attached yet. There are 12 wraps in the coil, making a 35' straight run. I can't wait to try it out next weekend.



I'm figuring the ribbing makes more surface area than a 50' chiller in a smaller package, and the extremely thin stainless makes it behave almost as well as copper in the conductivity department.

Wow you just might have designed the next big thing in brewing, I'm very interested in seeing if there is a difference in cooling.

Not so much an idea, as a "necessity is the mother of invention" moment. He had 10' of copper, or about 100' of this stuff. I opted to do a little more of this than a lot less copper than needed. I'll probably do a dry run tomorrow after I get my output hose clamped. I'll just boil 5 gallons of water and see how well it works, and make sure it doesn't leak like a sieve.

It's leak free, and the water is on the stove... Another 45 minutes or so and I'll know whether the time was worth it.

I believe that is similar to what MoreBeer calls their "efficient chiller." They use kind of twisted copper to increase surface area and create turbulence in the water flowing through.

I have about $26 into it including a new pair of pliers for twisting the copper ties. That's plate chiller speed, without all the pumping insanity... I had NO idea it would work this well.

It looks like it's very similar to morebeer's product, except I'm sure mine has thinner walls. They probably permit equal flow, and I'm pretty sure my kitchen sink was putting all of it's flow through the chiller so it's a dead heat there, too. I can't wait to brew up something hoppy and delicious to see what I've been missing by no-chilling.
