Over here in central NY we still have not boiled either. Last year my first boil was on 3/27, based on the forecast it may be again this year. In 2014 I was tapped by 1/20, this year we waited and finished about 6 days ago on newly added taps, a week earlier on the old taps. Last Sat. the temps went up to 38 degrees, so I ran the vacuum pumps (2), I burned 9 gal. of gas to get about 6 gal of sap. Late this week and all of the next 2+ weeks look good here, if only the ground thaws some.
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.
