We are fine here. I'm still boiling, but the sap sugar % has fallen to 1.0%. Will stop when it falls below 1. At 26" of vacuum I'm only getting 200-250 gal in 2 days off 398 taps. I thus boil every 2 because it would spoil if I hold the sap longer.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
