Here is my dilemma - I'm brewing in central Australia. We're coming up on some nice hot summer days and thanks to city planners, the local pipes carry bath water. While it probably saves my electric bill (not needing to heat as much), it sucks for dropping wort temps after a hearty boil. I also don't like the notion of running water through my counterflow chiller and having it run down the drain. I'd like to build something better, more efficient and hippy friendly.
I envision something involving a large-ish reservoir of water, a pump and some type of high-efficiency chilling system. Water goes in to the through port of the chiller cold, comes out hot, goes back into the reservoir, gets chilled and recirculated back through. I'm not afraid to go the route of employing something like a glycol system. The hoses, the chiller, the reservoir... not issues. The chiller... BIG ISSUE.
Any thoughts out there?
