WOW!!! That is awesome! I want to see more pics

That thing is unreal! I want to see some detail shots and hear about any tweaks you made to the design.

Great work!

Wow! Now that's freakin' shiny! Nice work, and yes - more pictures please! Maybe start your own thread and post a link here to not offrail this build.

I have done a second brew day and have now come to the conclusion I am not getting enough cooling capacity out of this double circulating method. I have put a very large bag of ice into the HLT and filled it with water. The hot wort circulates through the HLT and the cold water through the boil kettle. I get down to 120 very quickly but it takes another 20 minutes or so to come to an equilibrium at about 100 to 110.

Long story short, do you have other cooling methods planned? I am considering building a counterflow chiller or maybe going with a heat exchanger.

How cold is your tap water, WhiskeyFingers?

55° - 60°. Once I hit about 110° circulating the water from the HLT I then switch over and circulate tap water through the boil kettle to get the rest of the way down to 70°. This is painfully slow and inefficient.

Ahhh... yes. You can't start with the ice water. I thought I detailed that in this thread.... hmmm.

We ran some math on it and found that the 15g HLT is not enough cooling capacity, as you have found. What I have done to get around this is to set everything up as follows:

Fill the HLT with ice (like normal).
Hook up all connection like normal except the return to the HLT. Keep the hose running into the HLT as you circulate the ice water and collect the initial hot water into a bucket for later clean up. Continue this until the wort is below 120şish (should be 3-4 minutes) then connect the HLT return and circulate ice water to chill down to ale or lager temps. This has worked very well for me (the only difference with my current setup is I have a CFC now instead of a second coil, but that should be changing shortly after the new year!)

I hope that helps and I apologize for not making it clear. Woop.

Edit: Need to look at your system more before I comment again...

Ok, I like Boerderij_Kabouter's idea, as usual

What size batches are you cooling using this configuration? With a ten gallon batch I suspect that the ice will be nearly all gone in 5 minutes once I reach 120°ish.

Do you completely fill your HLT with ice? I would rather not spend another $10 per batch on ice but instead use the ice i have already in my freezer.

Since you speak from experience i will certainly give it a try.
