I have a built in flue damper with handle on side, a bi-metal thermostatic damper for internal draft, a dozen individual grates with teeth that move front to back, a metal screen for wood fire burning. Served me well over the years but I'm itching for a change.
Warning ... thread drift!
I wonder about how many versions were sold too. Don't know how many permutations of the "multi-fuel" versions were marketed. The "II" has what you've listed above. I'm guessing that the "Vigilant I" would have been the first revision to move away from the hopper/coal conversion kit. "II" is marketed as coal only. I'd bet it's just because the EPA particulate specification. "I" wood/coal combo
vs. "II" coal only
might be the only difference between the "I" & "II". You can see a lot of the "II" in the videos linked below my sig block. Hope to hear about this from other members.
I had to buy the screen and it seems to protrude just a little over the ash lip. Wonder if that's a change? I didn't come with the shovel like my old Defiant did.
Back on thread ....!
I like to use this calculator: http://www.fpl.fs.fed.us/documnts/techl ... ulator.pdf
The spread sheet version linked to on the first page is easy and quick to use. It normalizes each fuel cost to 1 million btus. It's not as customizable as others and, according to knowledgeable members, isn't quite as accurate. It doesn't list anthracite, just bituminous. I don't think comparing the two on the spread sheet's calculations is too far off as the consider bituminous BTU content hight at 26,000 BTU/Lb. This should adequately bracketed the two. With this calculator, the oil I bought two weeks ago at $2.05/gal ($16.53/million BTU) is comparable to coal at $430/ton. The most expensive coal I've bought this year, @236/ton or $9.08/M BTU compares to oil at $1.04/ gal.
