Wouldn't this work? (edit: no it wouldn't. Not pulling heat out of system)

E out = E in
(Sp Ht wort)(mass wort)(dT wort) = (Sp Ht water)(mass water)(dT water)

Solve for mass water.

• I first did Ice Bathes
• Then Ice Bathes with Ice in the wort (boiled and then frozen in ziplock bags)
• Then Wort Chiller
• Now Wort Chiller with a pump to circulate the wort (and create the whirlpool) ALL_GRAIN

Each move I saw improvement and some of the changes were because I went to 5 gallon to 11 gallon batches.

Question: Who is Jamil?

Former home brewer gone pro (heretic brewing) who was either the first or one of the firsts folks who pioneered proper yeast count among home brewers. According to Morebeer, was also the first to recirculate wort while chilling with an IC and publish its benefits.

So I ultimately am thinking I can squeeze a few minutes off my cooling time be seperating the coils slightly. While all of the wort moves a bit, its noticeable while staring at the wort where my chiller is by the flow of wort. What would be the best way to go about this? I would also like to permanently affix said chiller IN the brew kettle, so it'll have to be pretty well cleanable with a recirculation of pbw.

I never took heat transfer. That's the thermodynamic principle equation but dT is what gets you.

dT is going to be an integral across the cross section of the pipe and is going to factor in flow rate and a heat transfer coefficient.

I would recommend against totally fixing it into the kettle. Maybe a clamp or something off the rim that holds it a bit off the bottom of the kettle for more flow...

As for separating the coils I have seen it done as follows: Use copper wire to entrap each coil in an X of wire where the tubing sits above and below it. You kind of cris-cross your way up the chiller. Also, soldering/wiring each loop to the stem of the chiller on the other side.

I agree with the copper wire to separate the coils, and stirring your wort by whatever means works best for you, it really does help.
As far as water speed....If I can cool 5 gal in 15 mins pushing 2 gallons a min. or the same 5 gal in 30 mins pushing 1 gallon a min, I'll take the quicker cooling time, water usage is the same.

Hmmm. I think I have some stainless wire i can weave. Or if I used copper could a solder all if the wire to the coil so there's no gaps for **** to hide? Probably over kill since its in the boil, but I like my stuff really clean, I just don't like spending time to clean it LOL
