How Long Can You Idle Your Stove for?

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

I was just wondering how long you guys can let your stove run without haveing to shake down or add more too. Ive been trying to keep it going when I go to work but usually its just about dead by the time I get home.

Guess it all depends on your stove. I have a Hitzer 354, and that doggone stove easily holds a good fire for 24 hours and keeps the house warm with outside temps in the 20's. Very happy with that. :D

Burning nut coal in a 30-95 Hitzer, I went 17 hours without touching the stove. The fire was low but came back up fine when I shook the grate and opened the vent. With pea coal in the same stove I have gone 12 hours and it is still burning fine though definatley dieing down. My stove has a gravity feed hopper, so running out of fuel is not a problem when idling for those lengths of time.
The only redeeming value of winter is that I can have a fire in my stove.

when you leave it idleing that long does it still keep your house warm? If I get mine going good fill it up and turn down the MDP and air vents I can get it to last about 10 hrs and when I get home the fire is almost dead but its not keeping the house warm, and I usually have to add some wood to get it going again if I just add coal it takes a very long time to get back up to a good temp. I am burning nut.

Depends on how much coal your stove can hold & how hot you're running it. I would say, a rough rule of them would be maybe 12 hrs between refills but if you have anyone home who can just add a few shovels of coal across the top every 4-6 hrs you'll never be fighting to save an almost dead fire.

matrix, approximately how many pounds of coal is in your stove when you fill it? If it is too small a stove, it will be tough to keep the house warm for 10 or 12 hours.

My stove takes about 30 to 35 pounds total, and that will easily idle for 24 to 36 hours. But in this weather (20 degrees and windy) "idle" would leave my house plenty cold. At moderate output, like today, 12 to 15 hours is about the max.

Also, you mentioned a MPD. Do you have a barometric damper? That might help.

Edit: Oops I see Devil beat me by two minutes with the same questions. Got to learn to type faster.

Quite often i'll idel my 30-95 in the pole barn garage. Tend it once every 24 hrs. Come spring time , I do the same with the 50-93 , which is in the basement of the house. When ever I idle the HITZER stoves , I turn off the fan. This way the stove itself stays warm. Warm enough to keep the chill out of the pole barn garage. When I want to do anything in the garage , I give it air , and away it goes. I never idle the one in the house untill springtime , when the temps are up & down , but yet to cool to let the fire go out. And yes , it does keep the house heated.

What exactly are you calling idle, heat the house or just long slow burn time. I can keep the stove at 300* for 24 hours which is close to heat the house and do a fill once a day and I shake twice. I could get a way with shaking once, but that would just leave me more shaking and difficulties later. THis is why I bought a large hand fired is that I don't have to push it hard and get longer times between tending.

My stove holds about 20 pounds of coal and I am trying to heat a 1500sq house with cathedral ceilings maybe im asking too much of it. By idleing I mean to get the temp up to tempature the turn down the draft to get it to burn as long as possible.

Yes, it sounds like you are asking that stove to do way more than it is capable of, unless you have a super-insulated house.

20# of coal is not very much fuel.. you will probably have to augement this stove with some regular heat from you full-house system in colder weather.

Oh my yea your asking alot. My finished area is about 1600 s.f. and the basement where the stove is about 800 s.f more. The stove holds 80-100 lbs. of coal (if you go to http://www.hitzer.com and look for the model 82, you will see what I mean) You will need a much larger stove to do what you need to heat the place.

I've been burning around 60lbs per day, although the past week it has been colder than usual for this time of year (more like January for us). I have been in this pattern of heating: I have been going around 15 hours between shake down and loading from over night to the next afternoon, it will take all of a cat litter bucket of coal at this loading and sometimes a little more. The buckets are about 3-1/2 gallons. The fire is still very "strong" after 15 hours. Then I'll shake it a little and top it off around 10:30pm and it will take about half as much coal.

It's supposed to warm up a little over Thanksgiving, so I will probably stretch out the afternoon loading to around supper time. I barely have the draft knob open on the ash pan door - about 1/8" between the nut and the door. My stack temp is between 200 -225* using a magnetic thermometer about 18" from the stove exhaust. The manometer usually reads .05, baro is usually open a very little and will open more as temps drop and the wind blows.
