So, I'm in the midst of putting together my 20 gallon capacity AG setup. I already have (1) 100 quart pot (25 gallon), and my 24.2 gallon conical tank from Toledo Metal Spinning (pulling a Yuri DIY special).
My question is this... Can I get away with using a 15.5 gallon keg for my hot liquor tank? Both my mash tun and boil pots will be 100 quart, but if I can avoid purchasig a third $200 pot... I'd be happy. At no point I will need to hold the full 20 gallons, so I figure it should be large enough, right?
My system is going to be a true HERMS... I plan on running a copper heat exchanger coil within this HLT. Eventually it will be totally automated, but that extra $200 can be used for other stuff at this time, and I'm going to pick up about 6 or 7 kegs tomorrow for FREE.
