Average Usage Per Day

I thought I saw a post with this info and now I cant find it, so if it's a repost please forgive me. I am new to burning coal this year and am curious on average daily use by users. Weather bit or anth coal has different amounts also. I know there are alot of variables to take into consideration, but this isn't for scientific research so averages are fine.

Yeah, I use roughly 60 a day (24 hrs.) in my Mark III.

Most of the time the I run the Glenwood at around 400-450 degrees constantly, except in bitterly cold weather. To maintain 400 degrees for 24 hours I use about 30 pounds of coal.

What amount of oil, natural gas, electricity or propane do you currently use each year?
At the very top of the forum in the dark gray header is a fuel calculator. you can use it to convert your previous fuel use into coal use.

There are huge variables in fuel use.. based on how much house you are heating, how good the windows and doors are, how well it's insulated and where you live..

Here in Michigan, with my previous drafty old 3500sqft farmhouse, and a 2400 sqft shop to heat.. I froze with $1000/month propane use.. that changed to $3-600/month on anthracite coal.. that was 1-1/2 ton to 3 tons per month. so up to 200# per day!! Now that I've rebuild about half the house, I hope the coal use to drop.

In the past about 40lbs a day in the Alaska Channing.

My AA 130 can burn 20-30 lbs. on a warm day and 40-60 when winter sets in.The
Fuel Comparison Calculator probably does't take into account how much each
heater burns just to stay alive.I think most heaters heat well with a heat load
but the off burn time my be quite different with different units.You don't
usually turn it off for the days it warms up a little more than you thought it would.
It still averages out to costing us less than buying other fuels,plus you now have
a toy to tinker with.

Javier,

I'm no expert, but I understand that with a good anth appliance, you will burn less coal per BTU going to the heated space. Not because anth has more gross BTU [some bit is actually higher], but because the appliance can be made more efficient. So, you get to use more of the heat, instead of sending it up the flue. My Keystoker Kaa-2 is rated at 84%, and some more pricey boilers are higher than that. I doubt that an affordable device that can burn bit can be made to be that efficient, due to the volume of flue gas and what it contains.

....and the 84% is steady state efficiency, however we get the constant low burn BTU's as a gift. It does not get any better with a carbon based, affordable fuel.

Idling 200-250 F stove in warm weather around 20#/day.

400 F stove in cold weather around 40#/day.

Poorly insulated 1000 ft2 with rooms closed off for winter, house temps 66-73 F.

40# on a day like today--COLD & WINDY

Last year I kept a spreadsheet of every pound that went through
the stoves. The average use for the year was 40 pounds a day.
This year with two stokers running, it seems to be about the same.

Using about the same running the same temps on the stove, house temps 70-75F.
What size coal are you using?

Using about 40# in 24hrs, 1500 sq ft house, stove temps 450-550, room temp mid to upper 70's,outside temps anywhere from 4deg at night to mid 20's during the day.

Kimmels Nut. Actual size varies, less consistent than Blaschak.
