I had Thanksgiving dinner with a family that lives in a huge house. The large main floor was heated solely by an ornate enameled cast iron wood heater (although there is a backup heating system). A slow-moving ceiling fan gently circulated the heat throughout the open floor plan living area. Throughout the four or five hours I was there the heater was fed only three or four pieces of oak firewood. I was amazed at the heat output and the efficiency of the heater (it was cold outside that day). I have an open fireplace as well that heats my whole living area but uses several times as much wood as that heater.
You could look into one of those outhouse looking external wood heat systems if you live in a house. They are somewhat popular in my area. Some people also use wood pellet heaters. I do not burn wood, but I give plenty of it away. The smell drives my sinuses crazy and it would smoke the hell out of my neighbors because we are in the bottom where cool air and smoke settles in. A man up the road used to smoke us pretty hard but he died and his greedy heirs sold everything not nailed down before they put the house on the market. I would have bought that stove just to make sure it went but them bastards wanted higher than a new woodstove price for it. They found some idiot to take it off their hands though.
Coal heat is a far superior heat than wood BTW but good luck finding coal these days.
