Hey, I just saw Dana B's install thread. Looks like his was installed one day and running the next! Hah! It'll take months for me. I still thought I'd start memorializing my project now. Maybe it'll prompt me to take progress photos. I hope I'm not jinxing it though. I put a down payment on this demo unit: http://www.hearth.com/talk/threads/windhager-biowin150-automatic-pellet-boiler-52-000-btu-hr-showroom-model.117934/ Nice that it has the vacuum unit, and saved a few bucks. While probably not initially doing bulk pellet storage, I'm pretty sure I will. Nice project, labor savings. Bulk deliverers are starting to serve this area. Initially thinking gasifier, I had 11 sections of 8" Duratech chimney pipe installed in the existing exterior chase. Now, when he comes back to finish the job installing the chase cover, the chimney guy will be installing an insulated Simpson Duraflex Pro liner. This'll turn out to be the world's most expensive pellet vent! Probably not, but still. I can definitely recommend the installer though, Actual Chimney Specialists; they installed that 8" insulated chimney without removing any siding-did the work from inside the chase! That's about it for now. Still at least a foot of snow on the ground down to the basement door. Next post in a month.
