And over the years my head tank has kept getting smaller. My first was a 415 gal SS milk tank, then a 200 gal SS milk tank. Then I got a 150 gal round bottom SS tank. I do use most of that, but once it gets filled to about 125-140 gal, with concentrate, I then run it back thru the RO to concentrate further. First time thru is typically from about 2% up to 7.5-8%, second time I take it to 10-12%. I doubt I'll ever get a different head tank, I like this size feeding my 3x8. I always empty the head tank before shutting down so it can be cleaned the next morning.
Aside from the 100 gal head tank, you also want enough sap storage to hold 2-3 gal of sap for each tap you have. The other tanks can set on the ground, and you can pump the sap up to the head tank. It's far better to have more than one tank. That way every time you empty a tank you can clean it, then put the new sap in a clean tank. I do this with 3 sap storage tanks on the ground and at times all 3 are full. I process from one at a time, then wash it before adding more sap.

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.
