Heat Physics

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

What your not taking into account is that closing or almost closing the mpd slows the heated air down and gives it a lot more time to allow the heat it's carrying to radiate out from the stove. I'll take closed or almost closed anytime.

That's what I've been told Patrick, but it doesn't seem to be that effective in practice. At least with my set-up.
I got coal in my Christmas stocking. (Yey!)

When you shut it down, you shut down combustion, because no exhaust means no intake. And combustion requires air in to exhaust anything. Not magic, ying and yang. In and out. cause and effect.

Regarding the post about wood bio mass and sustainability. I disagree and you sound like some one that has drank to much recent college kool aid. Unfortunately, you have to have been around for more then 25 years to understand a forest ecosystem.
If this is not the case with you, then you are an industry insider and could care less that they are strip mining Maine to send "eco energy" to Mass. The same thing applies to your thinking that applies to MPD's. Cause and effect. Before you go yapping about how sustainable something is, get a historical knowledge about what existed before you did. The Lorax was right. Maine is growing a bumper crop of suckers and red maple, etc. That is the effect of stripping the land to many times.

Hmm, from reading this thread, it would seem that one small fan blowing on the stove hasn't increased the heat output to the desired level during this cold snap.

Might I suggest adding a second? :whistle:

You may encounter the effect called "diminishing returns". ;)
