I'm sure you won't be tempted to balance your beautiful new Blichmann's full of boiling wort on top of plastic milk boxes as is depicted on that site. Because THAT would be insane
But it looks like a great setup. I used that chiller for a while and found that it collected a lot of hops material - YMMV. I eventually switch to a counterflow chiller which has been working well for me.
I just switched to all electric and the first two brews are under my belt. Not too many issues during the first two brews but I figure I will still be dialing in the system for another few brews.
Don't sweat questions of efficiency, volumes etc at first - take your best guess and take careful notes about your guesses and then what actually happens and you will learn how to work with your system over time.
Have a ball! Got your first couple of recipes planned yet? Start with something you've brewed before or at least something fairly simple. Don't go for the triple-hopped Barleywine just yet
WooHoo!!! Got the shipped notice today!! I can't wait!! Been out of the hobby for a year now due to a move, had to sell my more beer tippy dump sculpture, could not afford to put it on the moving truck. I'm psyched and ready to brew!!
