8 should be enough once the sap really starts running, but early on you might need to save sap and keep it cold to add to another day or 2 before you have enough. You want enough to boil at least 3 hours on the first boil, or draw off what has been boiled and save until another boil.
Some have used mild steel and they seem to be usable, but between seasons, rust becomes a major issue.
Dave Klish, I recently bought 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.
