With coal, it's not like burning wood where you need to keep the pipe temps over 250 F to reduce the chance of creosote condensation in the chimney system.
High pipe surface temps is an indication of less coal heat going to the house. You want to try for the lowest pipe temps that the stove can still give you the house warmth you need.
Better to have a stove that can heat you out of the house now, than not have enough stove when the weather gets really cold .

That’s a fact. Before the coal would not heat like this. So it is either the change in coal or the addition of the insulation. I will try a mix tomorrow and see how that burns.Sunny Boy wrote: ↑Mon.

I'm telling ya man, sealing those bypasses makes the difference between it being a wood stove or it being a coal stove.
There's still trials to be had, yer not "out of the woods" yet haha. Clearing ash thoroughly in these sloped sided fire boxes is a big hurdle to get over. But once you have that part under control, I think you'll be pretty happy with using coal in that furnace.

Woke up this morning it was 75 in the House. Went down around 9am to check the furnace and it was out. At first I was disappointed until I started pushing the ash around. Here is 2 pics. The first is before I pushed the ash through the grates the second is after. I’d say about 90percent ash.
So my next question did I burn it to hot or did I not add enough coal?

If you didn't fill to the top of the fire brick + heaped in the center... it wasn't full.

It was to the top of the fire bricks in the center but not the sides. Kinda like a mound.windyhill4.2 wrote: ↑Tue. Nov. 21, 2017 9:32 amIf you didn't fill to the top of the fire brick + heaped in the center... it wasn't full.

That is correct. If you didn't add any coal after that last pic you posted of it burning last night, it didn't have near enough coal in it. This is where the baro will help you smooth out the burn.windyhill4.2 wrote: ↑Tue. Nov. 21, 2017 9:32 amIf you didn't fill to the top of the fire brick + heaped in the center... it wasn't full.

To elaborate on what I posted above, it sounds like it burned hot and fast because the house was so warm in the morning and most the coal was burned up.
