Silly idea floating in my head, and need some suggestions please.
What are some of the recommendations you guys/gals have for a small pump that will take water from one side and pass it through the other?
We are talking very small scale, low power, even battery power.
Not a wort chiller size or capacity.
don't know about battery power, but I use a couple of pond pumps to recirculate water in my pre-chiller, my fermentation chamber, my cleaning system, etc.
$20 - Lowes. Outdoor Ponds section. Submersible. Larger sizes available...
GPH is gallons per hour. The 3 feet high question you are asking about is called head space I think. So you can look for what the pump is rated at for that.
How I brew: Stir plate starters, Extract, Full boil in a Keggle, 10 gallon batches.
Brewing upgrades in progress: temp controlled ferment, stir plate re-work, building mash tun, milling station
Planned House Ales: an Amber, an IPA, a dark IPA, a Mango Ale, a blueberry oatmeal stout, a dry Irish stout, a honey wheat, Apfelwien
