I've been thinking about the cheapest way to get a whirlpool going on my IC (to enable something like Jamil's chiller
), and I think an airlift pump
might be the ticket; it's simple, I can make it out of just a few heat-safe & sterilizable parts, and most importantly, will be cheap!
What I'm thinking of doing is taking a bent length of 1.5" or so copper piping, attaching a heat-safe air line, and attaching it my IC. I was wondering if anyone had every done something like this before? I'm planning on putting together a test run soon, but wanted to see if this was just a good way to ruin a batch of beer, or frustrate myself.
