My fall back is to also use the mt as a secondary vessel to hold ice and water and cycle that through the hlt.
Like I said at this point its a theory until this weekend. Worst case I still have my ic. I don't have any of the inside handy but you can go to shutterfly link I posted at the top to see my album. I should have an inside shot minus the pickup tube.
do you see any flaws with this. I'm open to suggestions.
I have a RIM's rig, but recently added a coil to my HLT to try out HERMS and to use exactly as you describe for cooling. My coil is 5/8" copper, about 30' long. With a whopping 3 batches of experience with this setup here's what I can tell you:
Use tap water in the HLT to get the wort to as close to 100f as you can before you add ice. I put a garden hose in the HLT and pump the water to circulate while some is being diverted to waste to knock the temp way down. A single keg of ice will NOT cool an entire batch from boiling to pitching, so save it until you've gotten all you can from the tap water. I use a 20# bag of ice to get a 10ga batch from about 100f to pitching.
BTW... Nice looking setup.
