February 2014: The months tale of the "coal burning" tape

PostBy: lsayre On: Sat Mar 01, 2014 5:05 am

With February 2014 now in the record books, here is how it looked from my perspective:

Months average temp here = 19.48 degrees
Months total of heating degree days (HDD's) = 1,274.5

Coal burned for all of February = 1,754 lbs.
Coal estimated to provide DHW for the month = 112 lbs. (4 lbs. per day)
Coal burned to heat the home for the month (estimated) = 1,642 lbs.
Coal burned per HDD for the month = 1.29 lbs.
Average coal burned per day = 62.64 lbs total (with ~58.64 lbs of that for home heating)

Yearly totals to date (Oct.1st through Feb 28th)

HDD's = 5,050
Coal burned = 7,986 lbs.

As to savings for February:

We used to use ~3.75 KWH per HDD (back when we were all electric):
1,274.5 HDD's x 3.75 KWH/HDD = 4,779 KWH
Add to this about 356 KWH for one month of electric DHW and you get a total of 5,135 KWH
5,135 KWH x $0.132/KWH = $677.82 for heat and DHW only via electricity

1,754 lbs coal for the same task at $0.1215 per lb. cost us $213.11

Our estimated savings for February 2014 = $464.71

Feels good, doesn't it Larry to let some actual numbers show the savings. Makes it all worth while.
I had 1346 HDD for February over here.
Burned 1836.58 lbs
If I used the NEPA fuel calculator and plug in $3.80 for fuel oil this month and the cost of my coal at .115 per lb., I saved $418.91 last month.
I'm most likely still going to be in the red at the end of this year on the cost of the boiler and installation but it's getting real close.

Hey Larry,

Did you record how much ash was produced ??


Just curious.

Ash came in at roughly 2/3 of a tub for every 230 lbs of coal burned. I emptied the ash tubs 8 times in February. I believe my square ash tub (the one that came with the boiler) is rated to hold 17 gallons. And my round Behrens 2GS will hold 15 gallons. I probably fill them on average to about 11-12 gallons and 10 gallons respectively. Call it 86 gallons of ashes for the month. That's abut 39% of the coal that went in by volume coming out as ash by volume. Ashes would take up less space if compressed up or powdered as would be more the case for shaker grates. Lots of clinker chunks in my ashes. Some huge!

But the ash was not weighed.

How long has it been since you installed the boiler?

The only thing I can think of adding to this thread is that for February my boilers estimated efficiency vs. electricity (which is 100% efficient) came in at 82.2%.

5,135 estimated KWH x 3,412 BTU's/KWH = 17,520,620 estimated BTU's

1,754 lbs. of coal burned x 12,150 BTU's per lb. as delivered = 21,311,100 BTU's

17,520,620 / 21,311,100 = 0.822 x 100 = 82.2%

This is the forth year.
Normally as the numbers have shown, this year would have been the turning point but I've an underground oil tank that I want taken out this summer and it had close to 400 gallons in it. I used about 200 of that in the fall and will soon switch back over to finish it off.

OK, I've been reading enough. I'm a brand new coal convert thanks to ffcuz. This topic is one that has me just shaking my head. I must jump in!

I live in a Post-WWII era farm house in the Shenandoah Valley of Virginia, one story, two bedrooms. I've lived in it for four years/heating seasons and used kerosene (cringe) stoves for heating, one Perfection and one beautiful old Seigler. My heating bill averaged $1,200+ annually. My biggest hold up with a heating fuel change was my unlined chimney. Very intact, but no liner.

Working with ffcuz, he regularly preached coal as a heating source. It finally sunk in about the time a Reading Lehigh came available on Criagslist, which I bought for $700 and placed in service February 13th.

The rest is history. I am a new coal committee member! Hooked! I am a scientific analyzer type and I've used Excel to help me begin to quantify my results. The one thing I don't have to analyze is the warmth!!!

Since February 13th, we've had 607 HDDs. My estimated kerosene use for that period would have been about 69 gallons (607*.113) or about $300. The last I saw it, kerosene was $4.399 a gallon and climbing. (I stopped looking)

I've estimated my coal use since February 13th at 837 pounds (607*1.38) or about $104. Loose coal is $250 a ton locally.

In 21 days, I've realized nearly $200 in savings!!!!

I've spent an inordinate amount of time looking at what I've lost over the past few years by not being a coal user. I had all the symptoms and excuses. Dirty. Sooty. Blah blah.

I've enjoyed the forum and I've learned something every day. Thank you for being such a warm community.

Welcome to the forum!!! You have already seen the advantage of burning the black rocks. $$$$$$ savings!!!! Keep checking in and refine your burn. You do have CO detectors installed right?

Well FireFuzz , You just found how dedicated these guys are for the co detector cause,you as a fire marshall said you put into service a used coal burner but made no mention of a co detector :oops: ;) i would guess you will be a good addition to the co detector police force ,you do have more than one detector , right ? :)
