I used to power by generators and gas powered vacuum pumps and RO. I now have solar and I'm net metered, I now run everything at the sugarhouse on electric and I sent my excess to the grid, to apply against my home electric use. I really like the quiet and not having to haul gas for those things. I do still have 2 vacuum pumps running on 6.5 HP Hondas, each with a 4.5 gal gas tank. One is only 40' off the road and thus easy to carry the fuel. I use 2.5 gal cans, easier to carry a balanced load (1 in each hand), but my other one is just over 800' off the road, and the last 300' is thru a swamp. I need to walk slow because sometimes the muck tries to grab my boot. I'd love to have electric there as an option. Besides, even witrh the 4.5 gal tanks, I sometimes run out of fuel when the sap is still running.
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.
