Coming up on two full years with a GW100 heating 4,000[] of NC here.
1)Measure the draft, don't guess.
2)consider going 8" all the way from the GW
3)As others have said, 12% MC don't sound correct. How bout a description of the wood? Size, species, when cut, how stored
4)Congrats!! You own the hardest unit to get figured out. Which makes no sense, since it's got the fewest controls. Hang in there.
5)Outside temp obviously affects heat load. But if you load the unit appropriatly, the unit should work fine. I ran my unit much of the summer for DHW.
6)a 200 sounds way oversized to me. What was your heat loss calc?
7)Yes, this unit will wreck the inside of your house if you installed it inside the LA. You didn't install it inside the Living area, did you?!?!!
hh:
8) you may as well hold your hand over your ass as to expect significant help from GreenWood. Keep reading this forum, stick to the fundamentals, hang in there.
From my experiance, these units are good, but not perfect and probably not as efficient as the down-draft-induced design. But the learning curve is hell :smirk: In the begining of my use, I tended to overload, use the wrong wood, open the door too much, yada, yada, yada! I think it takes time to get these green beasts figured out. The problem you're going to have is trying to figure it out while your house is being destroyed by smoke. If you can get this unit outside, do it! Even if you have to burn oil for a month, it's worth it.
Oh, before I go . . . has your one-piece-refractory (Design flaw :shut: ) turned in to 7-piece yet??
