I love my pump and I'd be lost without it now. It runs for most of the brewday.
During the mash, it circulates runoff through a copper coil in the HLT, maintaining temperature, mixing up the enzymes, and setting a nice filter bed.
For sparging, I just redirect the output into the kettle.
After sparging I turn it off for the boil, but then it goes back on at about the 5 minute mark to circulate the boiling wort and sanitize the coil in the HLT.
At flameout I just fill the HLT with cold water and let it overflow slowly, and it becomes my counterflow chiller.
When the chill is finished I redirect the output into my fermenter (which can already be in place in the fridge).
Afterwards, I pump hot napisan through everything for about half an hour, followed by a warm water rinse.
It removes a lot of the stress, timing issues and heavy lifting from the process :super:
