Adding a third coil to the wort chiller. This makes 60 feet of 3/8 tubing. With a whirlpool effect, I think I can get 10 gallons from 212 down to 60 in 5-7 minutes.
Okay, it's official I can't help myself. I added a 4th coil.
The first time I tried to time the chill for 5 gallons I got frustrated that it was taking so long,I was at the 100'F mark in something like 5 minutes when I noticed my feet were really warm as I stirred the kettle. The burner was still on.
The next time I hit reset on the stopwatch (instead of stop) before I got to see the time.
Two days ago I prepared before hand and did it right.
With 80' of 3/8" coil, that's over 8 square feet of surface area including the riser. With the time from the last brew, 5 gallons from boiling to 60'F in 5 minutes and 30 seconds, and those measurements I've calculated just over 2640 BTU/hour or 775 watts of cooling power (with hose water temps @ 50'F)
