Efficiency on the other hand, has many,many variables and can and does always change.
What are trying to accomplish?
Use lesser amount of coal and get the same amount of heat?
Or get more heat and use the same amount of coal?
It is not clear to me what you are after.

I'll check that tonight, but I have one of the original units, I think, which had the original blower before you guys started having issues.

What I will say is that w/ this blip of the mercury downward and then it returning back to the more seasonal expected temps, it is no crisis to be dissappointed w/ the heating falling a little short of expectations.
I say this because this temp we just had is in fact below what most Heat Loss calculators use.
It will likely be some ?decades? till we see it again. In the mean time, maybe just figure a Plan B where you could bring on "supplemental" heat for if/when it hits in the next 30 years.
A nice hand fed would do.

You have to "feel" your system respond or not to cold, wind, different coal, drafts, and many other physical inputs. Having said that you have your temps so low,(to my thinking) and you held at 70* is amazing. How many btu's did you leave on the table by not having your boiler adjusted for max? I knew a plumbing and heating guy that declared,(while we were building his house) that he was going to heat his house with 75 degree water. PIPE DREAM! He had 2x10 walls in the walk out basement. and 2x8 walls in the house, and spray foamed it all....etc. Reality check folks. He had $100 grand in windows that were an R3.5 on a good day. Lets just say he had to increase his supply temp a bit. I am the type that would like to measure and quantify everything. Like Isayre. But everyone has to get a handle on their own home and conditions. IF it ain't working, turn up the coal feed or turn up the water temp. Stop screwing around with "max" efficiency and wondering why it isn't working. How much are you saving when you are burning the cheapest form of heat you will ever see?
Of course in the back of my head I can hear Sting raving about only putting out the btu's needed to satisfy the demand.......and something about balance. Well, if it ain't heating, put out more heat!!!!!
