Has anyone ever tried an alternate method of wort chilling by which you pump your hot wort through an immersion chiller that is sitting in a bucket of cold or ice cold water? This seems more efficient to me than the typical method of pumping hose water through an immersion chiller sitting in the hot wort.
I'm considering switching to this method but was wondering:
A) Has anyone tried this yet and if so, does it work?
B) Are there things I should be concerned with in implementing this method of chilling?
In my quick scan of the replies I didn't notice anybody mention the biggest problem with this approach... Sanitation. Good luck trying to sanitize the inside of your IC. I have been using a Jamil chiller for about 5 years now and I am very happy with its performance. 5 min to below DMS conversion temp, 5 more minutes to 90. And that is with my hot groundwater in Phoenix. Then I switch to recirculating ice water, like Boog said. I also collect the first 5-6 gallons of hose water in my MT for cleaning. I estimate 15 gallons or so to chill in the summer. In the winter time, I just recirculate 50 degree water from my pool. No waste. I typically brew 80% of all the beer I brew in the cooler months, anyway.
