Ok, I'm new to the coal burning as of this year. I've been burning my stove for a few months and with the cold weather upon us I'm wondering how hard to push it. I am heating my entire house (2,000 sq ft) with it and it is doing well. I have the bigger Hitzer hopper fed stove 50-93 with a baro in place and temp gauges on the stack and stove. My stack temps remain less than 200, usually near 150. My stove temps are currently at around 500. I've kept them at 400 or less until the sub 30 degree temps. What temps do you push your stoves to for sustained use?

I'm guessing that I'm not pushing it too hard as I'm only using 40 lbs/day so far but I'm just now starting to push it harder.

I do love the coal stove, I can't believe how much better it is for me than the wood stoves that I was constantly working to keep filled.

I have the 30-95 and my stove is currently running 375 - 450 depending on the day. I am heating 1500 sq ft. I bought the magnetic thermostats that TSC sells, one for the stack and one for the stove side. The burn range on the stats run from about 250 to 600. I will try to stay within that range. I would think that 500 should do the job in even the coldest Southern Michigan temps.

Do a search on Stove Temperatures, it varies, but 400-550 is not unreasonable. Even my stoker will run 500-550 on the front/sides when really cranking.

I just cranked my Mark III up to 2 turns out on the air inlet. 550° on glass, 580° left side top center ..... and 630° a foot lower in the firebrick area. Stack is close to 300° measured right at the exit .. so probably 250° farther up, pulling .05" w/c.

good information. I will probably try to keep it at this temp then and not push any harder. I think that I may need to get an IR thermometer to get some accurate measurements since I'm only going by the magnetic stove thermometers.

thanks for all of the helpful information.

If you want something to worry about, it would be the stovepipe temperature. If it is glowing cherry red, turn the stove down.

Only time that's ahppened was when I was a woodburner and the ceosote buildup ignited in the heat exchanger and stack. (I stopped burning wood that day). Way to close to having a major problem. Don't have that problem with the black stuff :D

Any idea how hot it needs to get to glow? I remember seeing the pipe on our trash burning stove glow, but that didn't last long.

Where you have it, it's just about perfect on the high end, if you get your stove over 600 , it only means that some parts of it, are already in the 900 range, and by then , the metal is expanding, and it may not go back to its original shape, you'll be asking for problems with leaks later , around some of the seal areas !

I've hesitated replying to your post, due to not having a thermometer on the stove itself. I have it on the stack only. The average cold winter days, my stack temp settles in about where yours is. Edit: I took the thermometer off the stack, and put it on the stove body, just below the back draft dial. I came home five hours later. The thermometer read 375*. I put it back on the stack. It went down to 150*.

I used my infared thermometer on my electric oven ..... a faint glow of the heating coils started around 790° .... by 850° dull red .... 900°+ you'll see it glowing no problem in a well lit room. That's some serious heat for the stack of a coal burning appliance! :shock:

What does the owner's manual say? That should give you a good idea of the maximum safe temperature you should achieve. My Mark II says 600* but there is no way I'm going that high intentionally; we'd have to leave the house. Safety first. Good luck, Lisa
