I just got back home from buying another Gingerich RO, it started as a 125, then a second membrane was added, now it's a 250. I need a 2x5 or 2x6 evaporator, prefer raised flue but will go with a drop flue if that's all I find and a vacuum pump.
My back up plan if I don't find an evaporator, is to use my propane 2x6 finisher for a year. Looking for wood fired, but will consider oil too.
