What size will the "temporary" sugarhouse be?
You might want to consider building a smaller permanent sugarhouse, then add on in the future. Make it a good size for what you think the largest evaporator you'll ever have with adequate space around it, and build it with the drains and all. Design it to tie into later as you grow. Then as you need more "sugarhouse" you can have a boiling room, and additions for a kitchen, wood storage (if burning wood), barrel storage (both empty and full and sap storage additions.
How many taps do you anticipate maximum?
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.
