Why not? If its lead free it should be fine? As I understand it the copper itself is more of an issue than solder.

Actually I heard the copper is good for your wort and recommended, to place it in the wort for the boil. I heard that from brew strong podcasts.

Ashton Lewis from Brew Your Own (amongst others) doesn't seem to think so...

"Brass, Copper and Carbon Steel should never touch beer... Ever", to quote his book.

My immersion chiller is copper with a fair bit of solder. Personally I have no beef with copper or solder

So in brew your own Palmer says copper is beneficial to yeast. Copper is bad though if it builds a layer of verdigris.

Beer is different than wort, no?

What are the lengths of the coils in each level?

Not knocking your design, I think it's pretty cool. However, you could have built a counterflow chiller that uses 1/2 that amount of copper and just as (if not more) efficient. Again, kudos for thinking outside the box and I'm sure it works great.

Not to take this too far off subject, but counterflows are not always the best option for all rigs. My personal setup is built to whirlpool the kettle, in which case I can kill two birds with one stone by using an immersion chiller with the added bonus of not having to worry about cleaning the inside of a chiller or losing flow rate required for good whirlpool-age. Of course, this situation does not pertain to everybody. What should be taken away from this design is the concept of cooling coils set at specific heights without having to bend your chiller to look like it came out of the front suspension of a Dodge Caravan. (Variable rate spring humor, anybody?)

Now what I am most curious about is the dynamic flow of water through what are essentially manifolds. The pressure inside a vessel is equal throughout the vessel only applies to a static environment. Since you have fluid flow and restrictions (tubing sized down from 1/2 to 3/8) I'm wondering if the return manifold might hinder flow through the lower coil. I doubt any hindrance will be very much, but much like the cat, sometimes I just gotta know!

So, HTC, I was wondering if you might happen to own an IR temp gun or some form of thermometer that might quickly and accurately measure the temperature of the outside of those coils. And if you do, would you be a sport and hook that chiller up to a hot water source then monitor the rise in temperature of the two coils as it heats up? I'm sure that eventually the two will hit equilibrium. But I wonder if the upper coil might warm up a little quicker than the lower. To quote Bill Nye, SCIENCE RULES.

The more I think about this, the less I think turbulence in the "out" manifold is going to matter, but I would still love to see that come true in an experiment.
