I have scoured this website and found tons of information to help me. So far have gotten a wiring diagram and parts list. most of the electrical stuff i can get from spare parts at work and I have a keggle. I was thinking of making my setup with one E-keggle for the boil and to heat water for the HLT. Then two 10 gallon coolers with pumps to transfer from E-keggle to HLT then to Tun and another pump from mast to E-keggle. seems like it will work. does anyone else use just one heat source?
