Pounds per day used?

PostBy: rschoensta On: Mon Jan 29, 2007 7:01 am

Anybody keeping accurate track of the pounds per day of coal for 90,000 K rated stoves? (Or any other for that matter)
I have a 90k stove and it's been running at 100% for the last few days.
(average temp probably around 0 degrees).
I have been weighing the coal (just started doing that) and it looks like I've used about 62 lbs per day.

I burn about 50 pounds per day in a Keystoker 90,000 BTU insert (early eighties vintage). The stove runs flat out 24/7 to heat a room with a 26' vaulted ceiling.

Best regards,

Hey, Rich,

Stat set @ 71 degrees. Temp rise is 90 degrees. It's just crusin' at this setting. I'm heating about 1100 sq. ft.

I love this heat!!!!!

Keystoker 90 - around 50#/day when it really cold below 20. (will find out in the new house soon!)

I mark it on a calendar and keep track of it each day.

I have a 180k Leisure Line Hyfire 2, for the last several days I have been burning 108 lbs per day. I heat a 150 year old, 2400 square ft farm house. Am actually heating more space than that as the stove is in the basement and that area is heated, so in reality I am heating more than 3000 square ft.

I have kept daily records for this unit since installing the stove three years ago. I use 6 tons a year.

The stove paid for itself in two seasons, the spreadsheet I use projects what the natural gas costs would be per month based on a four year average and todays cost per natural gas unit.

My house is about 2200' and I'll guess the boiler is about 120,000-140,000 BTUs. I'm running about 80-100# a day now that it is cold. It's 74* in the house. That's about $9 a day, I can live with that.

I'm also burning about 50# when the temps are like we have now. My Magnum stoker is also running flat out. When it's a little warmer I do about 33# a day. 100 # hopper will last 3 days.

Keep warm!!

With my Harman Mark III I'm heating about 2400 ft in a 200 year old farm house. House never goes below 72 even with sub zero temps we had recently. In fact when I got home yesterday my wife had the house at 77 degrees. She calls this her comfort level. I guess that is what I get for showing her how to run the stove. I'm also heating all my hot water for the house. I'm going through 4 coal shovels full a day and I figure each shovel weighs about 20 pounds. So put me down for 80 pounds.

The last few days its been -10* to +15* here in Central NY. My Keystoker 90,000 Btu has been burning around 45 Lbs. Before that when the temps were in the 20*'s near 30* it burns around 30-35 Lbs, That's in a late 1800s farm house with 2500 sq feet. The oil fired furnace still kicks on every now and then but not like it did. I have only been burning coal for a week and a half now and wish I had been introduced to coal years ago.

With temps at about 15 degrees at night to 20 - 30 degrees in the day, I'm burning about 50 lbs. per day in my old 70,000 btu Alaska Stokerstove with a water coil to heat all the domestic water. This is with the stove running about 3/4 capacity - probably will use 60+ pounds at full tilt. The house is around 2,000 sq. ft. , 2 story and well insulated. The stove is in the basement and the living room above the stove is at 75 degrees right now with the outside temp at 16 degrees - very comfy. In the coldest temps the elec. heat will kick on upstairs but I'm working on installing a register to distribute some warm air up there.
My wife does the same thing as Rouxzy's does - I'll come home and find the temp to be 78 or 80 and ask why its so hot and she'll reply that its just comfortable!

I have a 1500-1600 sq ft. home built in 1950. It’s has medium insulation and all the windows are new. I try to keep my house at 71 degrees with my Warm Morning hand fired stove in my basement, which is tied into my duct work.

For January at our airport per accuweather.com we had 1016 heating degree days this month.

I averaged 69 lbs / day for a total of 2126 lbs this month. That is $196.66 at the $185 per ton I am paying right now. Per every heating degree day, that is $0.20 on average. This is only home heating, not water coil yet. I’m saving over last years natural gas prices (which prices came down since) but my thermostat was at 65. Since I’m just paying to heat my domestic water and cooking my gas bill is low, and the less gas you use the more you pay per cubic foot. So I’m not sure what a 1016 heating degree day gas bill would be with today’s prices, I don't want to find out and be cold at 65. My gas furnace ran just a few times when I came home after being away for 28 hours, and my house got down to 64 degrees.

I am trying to keep the firebox full, and fire slow… that seems like everyone recommendation here. We had some cold days here in PA, and I was keeping the draft at -.06… on days with low wind and lows in the 20s, it was normally at -0.05. I’m going to shoot for more air below and max -.05 this month to see if I can get more heat for less.

I have a lot more work to do to make my system more efficient. I won’t be able to do it overnight, I wish I could. My biggest shortcoming is the lack of a cold air return system. Right now I’m just heating cold basement air, but I am going to build a filter box this month and start warming air that is already warm.

how much coal
