Yea can't wait till it's done. I feel the laundry list of parts is never ending. What burners are you using and how are u controlling them? I'm trying to automate at least flame control and pumps.
Im using 32 jet, jet burners, that is 320,000 BTU's a burner, I think I could have tuned that down to 24 jets but too late for that, they are controlled by an on/off valve and a needle valve to adjust, I can get thru one batch with a 7 gallon propane tank in a water bath to stop freezing and keep the flow going. (I have a 5 gallon for backup in case I run out).
I see you are using a HERMS so automation on flame would work good for you, I wanted to automate flame but it was too expensive and im running a RIMS.
Also just had my mash tun sent out to get a heat resistant wrap made for it, found out that brewing in the winter with cold grain and cold stainless makes for a long brew day, but again your HERMS will change that for you.
