For sure, I swirl my chiller around every 5 or 10 min for the same effect.
The benefit of the automation is that it's constant and about 20min faster to get to pitching temperature than swirling every 5 or 10 minutes.
I'm probably going to sound like an areshole, but unfortunately, that's my nature, but if you had clicked on the link and read the the article you would have had a slight understanding of what the **** is going on in the thread.
no-one cares if you're happy swirling your wort every 5 or ten minutes or if you can afford a pump or not.
If you need a cuddle to feel better, please let someone know
Cheers,
BF
