Harman Mark I New Owner

Glad you got everything worked out. What sort of burn times are you getting with the MKI?

Did you find any clinkers or just ash?

Just fine ash. I have not really had any clinkers with this load of Redding nut coal. Every once in a while when I shake I'll get some resistance but nothing that jams the grates totally.

My normal routine is 12 hours at 400-450 degrees on the top of the side. Tending the stove at 5am and 5pm (before and after work). But I have got 15 hours at those temps on occasions where I was not home at a normal time. The longest I have got out of the stove is 21 hours but it was running very easily on one of the warm days in December.

I'm not sure on bagged. I purchased bulk coal back in late October and it was $248/ton if I remember correctly. I got a shade over a ton in my dump trailer. I have a tarp over it to keep it dry and I just shovel the coal right out of it into a wheel barrow. So much easier than messing with wood.

I can call or drive over there one day and see how much it all is.

Thanks

Since its been so cold out and technically Winter now I figured I would check in here and revive my old thread on my Harman Mk I. I lit up on Thursday night when I got home from work. The little Mark I has carried my house through the extreme cold temperatures the past few days. 85 degrees in the basement and 70 degrees upstairs. I think we were around -7 degrees and 30mph winds Friday night and all day Saturday. Really brutal out. I really ran it hard the last couple of days going through about 25-30 pounds of Reading nut coal per day. I have about half a ton left over from last year. Haven't bought any yet as I hear it has gone through the roof. Hopefully what I have will get me somewhere into February and I will just wait and see what the temps are like. I may end up just running my natural gas furnace the rest of the winter after I run out of coal. Natural gas is still dirt cheap, however, I much prefer the radiant heat the Mark I provides. House feels more comfortable with the coal fire versus the forced air heat from my primary furnace. ¯\_(ツ)_/¯

May I suggest a bin in the basement to complete your transformation. Just pull the truck up and drop it in. If you can position it near the stove you can shovel it directly in without moving your feet. Nice.
