Hey man, excellent setup. I imagine you get a lot of envious replies when showing this off.
Question for you - I'm still working off a blichmann kettle w/ igloo cooler MLT setup and am looking to move to either two blichmann...or even three for the hot liquor tank. I'm assuming from the photo the pot on the right is your kettle, the left is your MLT, but where does you hot water come from?
