Harmon Super Mag Is in and Is Throwing Great Heat.

A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

Awesome results you are getting!!

I found that having a second ash pan is helpful. But with my basement installation the local decorating committee has not complained about my process which includes leaving the second pan next to the stove. You may be in a different situation!

In the morning I swap out the full for the empty, and there is no need to throw the switch to keep the ash from dropping off the grates while there is no pan there.

I leave the full one next to the stove to cool off. Minimal bonus heat from the pan. No hot ash floating up from the pan as it gets carried out.

After the pan cools I take it outside to dump, either that night or next morning whichever weather is less nasty. If heavy rain/snow persists, then I swipe the pan from the hand fed and bring it into the rotation too!

I just open the ash door and grab the front lip with my right hand and slide the pan out enough to grab the handle with me left hand. Once I have the pan in hand carried by the handle I just shut the ash door with my right hand and walk out to dump it. I don't shut the stove down anymore. Seems most times the ash doesn't drop when the ash pan isn't in place. I used to open the fire box door and use my long poker and just scrape down the last inch of ash into the pan. This would give me time to empty the pan without ash over the edge of the grate. I have a switch on the stove but I forgot once to turn it back on...not good. So this way I do now is fast and efficient. Oh...I use a nice pair of insulated leather work gloves as the pan and handle can be hot.
