Woodburners sound off!

I heat with fire in my shop, some wood, mostly coal. Smells better, burns hotter and longer.

So, I have burned wood in a modern, fan forced, 64% efficient fireplace as my primary heat source for the last 3 winters. I have a 500 gallon tank for my propane furnace, but I only burned 16 gallons last winter! (Thermostat for furnace set at 59 and a whole lot of splitting Ash and Oak! All other appliances are electric!)

How do you do that? The heat-exchanger on my basic furnace is y to small to be a fireplace.
