We're going pro in a few months and are having a 3 bbl system custom built for us, pretty much what Hess in SD has but bigger. I understand that with all that thermal mass in the mash tun, it wont lose much heat through the process, but I still want a way to control it, I'm thinking of wrapping 100' of copper tubing around the mash tun and circulating hot water through it to keep the temperatures constant, has anyone seen this done? Any reasons why it wouldn't work?
