Try some birch syrup before you go that route. Some like it, but many don't, but it can give you more use of the expensive equipment. Some of those who do both, find it may not be a good fit, an evaporator sized to handle 500+ taps might be well oversized to do let's say 150 birch taps.
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.
