Wow really?? Did it chill on the first pass?
I did it. Once.
It took 42 pounds of ice to chill 5 gallons of wort.
Does anyone fill their HLT with ice water post boil and push their wort thru the coil to cool it? How well does it work?
No. I kept adding ice as it melted and ran it via pump to recirculate the entire time. It was a huge pain- mostly because I have a single tier with pumps to avoid so much lifting (I'm a 135 pound grandmother). Hauling ice out of the chest freezer in the basement, and 42 pounds of it, was a huge pain.
My friend is an engineer and later did the math for me, showing me that indeed it would take 42 pounds of ice to chill 5 gallons of 212 degree wort to 70 degrees.
That did not make me feel any better.
But it made sense once he showed me the math. Then I bought a CFC for the next brewday, and I'm still using that (it's been about 8 years).
I don't suppose you know how he calculated that do you? I was planning to give it a shot to see by just passing boiling water through it to see how it does, but it sounds like I might just invest in a plate chiller.
