How Low Do You Let Your Stove Go?

How Low Do You Let Your Stove Go?

PostBy: Devil505 On: Mon Oct 29, 2007 1:08 pm

I just fired up my Harman TLC-2000 for the winter. For the next few months I typicaly just need to keep it idling during the day to keep the house comfortable while saving coal. The stove is a top vented 6" chimney design to which I have afixed a magnetic stove-pipe thermometer about 12" above the stove to moniter the stove temp. I find that (exhausting into my masonry chimney) I can get it down to about 120-140 degrees (with outdoor temps sometimes ranging up into the mid 60's during the day, going down into the 30's at night) & manage to keep it going.
How about you?

Does anyone know of a stove temp alarm that will alert you if the stove temp falls below a certain setting?

Typically you want to service a hand fired about every 12 hours. This keeps the coal bed happy and loaded with fresh fuel. Properly tended, the fire should burn until spring with a good unit. Good luck!

You are right but I have found that, if I keep the fire real low & add a few shovelfulls of coal carefuly once or twice , I can get by with only shaking the stove down every 24 hours! (Saves coal & creates less the dust!) I admit that doing this puts me right on the edge of losing the fire but I work out of the home so I am around to moniter it.
Takes a bit longer to shake down (carefuly) & refuel after 24 hours but it worked great last winter. (Haven't had the opportunity to try it this year but with temps so mild it wll be more of a challenge since the chimney draw is reduced.)

I've been trying to get longer burn times from my Mark I, I came home earlier this week and it was out. I've noticed that since I began banking the coals and adding coal with the shovel instead of pouring it in from the scuttle (filling up the low area in the coal bed-avoids the gas explosion) in conjunction with a little more vigorous shaking (I continue a little bit beyond the point where the first embers fall into the ash pan) I have been able to get longer burn times. My objective is to keep the stove going. With good coal and some charcoal to start with it's not that hard to start it, but why create the extra work (before restarting I empty the stove completely).

Well I have a TLC 2000 and right now my stack temp. is 130. Bottom air open to second notch.

I have always burned nut coal, but I can also burn pea and stove coal in this stove. I decided to try some pea and I think I like it better than nut. The pea requires more air than nut.

Time will tell when the weather gets colder, but so far so good. You just have to be a little careful when shaking pea. If you go to far you could dump your fire.

Two tons of bag pea on hand and about 200 lbs of nut left over from last year so another ton of pea should just about get me to spring.

Exactly. With the Harman shaker system, push the lever a little too far, and it's in the ash pan.

I push/pull the lever about half way through it's travel each way. When I had the bad coal last year I had giant rock hard clinkers that got stuck between the 2 grates. At that point I just had to empty the stove and start over.

Absolutely. You hit the nail square. :)

Then once in a while, you go to shake and fill the stove, and all thats left burning is an area the size of a softball. So you open the ash door, put half a shovel full of coal on the bright spot, and baby sit the fire for an hour until have most of the firebox burning again, and you can finally shake it down and fill'er up. I've often thought that it would be quicker to start the fire anew than go through that rigmarole, but then you wouldn't be able to say that you only needed 1 match for the entire heating season. 8)

When I was burning nut I could go 24 hrs with no problem if it was warm out.
I don't know if I want to try that with pea just yet. I'm just in the beginning stage with pea. Besides being on a 12 or 14 hour makes everything so quick and easy. I just make sure I do it before bedtime and I'm golden until sometime early or late in the morning.
