WOW How far I've come since I started this thread! Time for an update?
So I've certaintly learned alot.
Ash door now fits snuggly. Little true-ing up with a grinder went along way.
Changed the mica a couple times, wood fires are hard on them.
I broke a grate, and had all 4 new ones cast at Tomahawk Foundry. They should be good for another 100 years.
I melted the cast divider in the back pipe. Oops... So for now I built one out of 3/16 steel plate. On the list to get a new one cast. Been working good for a year now like that though. Was operator error.
I've learned the importance of sealing all the pipes and metal to metal joints. I've gone over 75% of all the joints this summer with new sealant. Drastic improvement. I can actually control the fire now.
Learned I must have a window open slightly on warm windy days for the draft to stay consistent. Set off the CO2 alarm a couple times to learn this. Seems a southernly wind plays havoc on my chimney draft. No problems since.
So performance results - I'm heating 3000sqft using a couple fans to move air. No problem down to single digit outside temps. I can roast you out of the house if it is in the 40's.
I've been able to idle it down low enough to get a 36hr burn and still have plenty of coals left to have it roaring in about an hours time.
Typical temps - load 3 times a day and I can maintain 700 degree barel temps with temps at the wall chimney around 200. That's for the coldest days. I can only get about 10 hrs before I have to tend to it.
Typical 30 degree days, tend every 12hrs. One full coal hod. Barrel temps 400, pipe temps under 150. House stays about 70 degrees throughout.
I've also been successful at mixing Bituminous coal. (which is under $100 a ton here, compared to close to $300 for Ant.) I load a layer of Bit first, then cover with a layer of Ant. I'm using about 40% Bit and 60% Ant. The Ant acts as a screen for the Bit soot and keeps the backpipe relatively clean. You can see the tar-like soot build up on the Ant coal, then it burns away clean. (Just straight Bit coal would clog the back pipe in under 24hrs. Been burning this blend all year and no problems yet. Cleaned the pipes one time and it was not much worse than just with Ant. coal)
So in conclusion, these old stoves are the best, and I couldn't have done it without the help from everyone on here.!!
