I spent a long time looking at the immersion chiller threads and google image searches trying to come up with the best bang-for-my-buck design for a wort chiller. It was built with 3/8" OD soft tubing, and 1/2" hard pipe and fittings.

I'm not going to go into theory for two reasons: one, because that's covered elsewhere on this site in unfathomable depth; and two, 'cause I've been celebrating the success of my handy work and I'm in no condition... In summary, use small diameter tubing (cause it's cheap) in short runs ('cause it heats up fast) throughout the wort (so's to spread around the coolin')
There. Theory.

My success? No brew today, but I got anxious and tested the chiller on 5 gallons of water on the stove-top. Using 52 degree F water from the garden hose I went from boiling to 70 degrees in roughly 5 minutes.

I say roughly, because I turned on the hose before I readied the timer on my phone, and the back pressure from the in-line ball valve caused a leak, so I opened it and started chilling to avoid death by wife due to flooded kitchen. There was probably about 15-20 seconds worth of panic before I gave up looking for the timer and realized the microwave has a clock.

I did manage to steady the camera to do the fancy talking for me.

Very nice. One practical consideration: Sometimes when I'm making a big IPA or American Barleywine I use a TON of hops and consequently hop bags. I find with my 50 IC that I barely have enough room in the middle of the rings to put the hop bags while I chill/whirlpool. This design looks like it may make whirlpooling a bit of a challenge.

That said, I'm very impressed and have been hashing out a HERMS coil in my head and this could work out very very well. Seems like minimal recoiling to boot?

Nice work.

I kind of like this idea for getting around the element in my electric kettle. It would eliminate the need for clever bending and wiggling for placement.

Nicely done.

Barely any recoiling, it basically comes in that shape. I just tightened it up starting in the center and worked my way out one side at a time.

As far as whirlpooling goes, I was planning on using a drill powered paint stirrer through the center of the coils - not fast enough to draw a vortex, but enough to move the wort with some vigor. But since you mention it, whole hops might make things interesting and hop bags of any useful size are definitely off the table.

Thanks for the feedback!

Another perk to this design - it's expandable. So far the coils are about 8" in height from the bottom of the kettle, I have room for another set under 5 gallons worth of wort in my turkey fryer. If/when I move to boiling in a keggle, all I'll have to do is cut the risers, add some coils and the chiller will grow with my system.

Also worth considering - I was planning on using Bobby_M's method of soldering a barbed x garden hose fitting over the end of the riser, but when looking at water supply fittings I found 1/2" pipe x 1/2" MIP thread adapters and the corresponding garden hose adapter to be a cheaper alternative. It also adds the benefit of adaptability - almost everything can connect to 1/2" MIP thread.

Nice, but I'd personally rather not have all that solder sitting in my wort.
