Pdiamond, good to hear from you. I was wondering what you were up to since you hadn't said much during the season.

We were able to get between 30-40 gph on the raised flue set. The average was 30-36 gph but there were some times we got it to 40 gph. Stack temp ran about 500-600*F. A few times when the stack temp got to 600*F, Elle would do a small firing about every five minutes, thus keeping the stack temp at a constant 600*F or raise it. That got our boil rate to 40 gph for a bit. Our stack is twice the length of the evaporator but we are thinking we may experiment for next season and add another section of stack to increase the boil rate. Overall, we are pleased with our rig. It's the second year running it but first year we ran the rig to the point of sap in front pan, water in back pan (last year our stuff went ropey). We RO as we boil so our 80gph single post from the RO Bucket pairs very nicely with our pan set.
