That is exactly what we did. It was certainly a group effort for us even if that is not what I wanted. I pumped the wort back into the kettle and checked the temperature. It was nearly ninety. I then looked at the valve on the garden hose and it was barely on. Opened up the chill water and the temperature dropped within seconds to 82. Then I unplugged the pump (I really need a switch), lined up the fermenting buckets, and filled them up.I used mine the first time a week ago for a double brew day. It worked great. I just need to work out my new layout. Lots of connecting and disconnecting.
You're right about it being quiet. Can't hear it at all with burners on. My favorite aspect so far is how I can use my CFC. I can recirculate full throttle until the temps coming out of the chiller are what I want, then switch directly to the fermenters. Much faster than what I had with just gravity.
