Here's my wood stove, a 1960's cast iron "Jøtul #4". When it was designed there was a rage for all things Pacific and "tiki", and this is reflected here. The "Jøtul #4" is obviously inspired by the statues on Easter Island. It has that convex eye ridge and stoic expression. The statues didn't have nose rings but some artistic license should be tolerated.
A great boon with this model is that the front door slides downwards and under the oven, so it doubles up as a fireplace (below). This is real luxury mode, the wood burns quickly and the room is not heated.
That's a water heater on top of the oven, great for washing off all those blood stains after a quiet afternoon spent splitting logs. The oven is not much good for preparing food apart from long-simmering stews. You'd just end up heating up the room to sauna-like temperatures.
There's a whole world of theorizing about how to improve the efficiency of a wood stove. Chop enough wood, sit comatose long enough in front of glowing embers, and this kind of speculation comes naturally.
The burning wood sucks in the air from the room, and then promptly sends it up the chimney. Certain industrious people have been upset enough about this state of affairs to create an air intake to their oven from the outside of their homes.
Another trick is to extend the stovepipe horizontally under the ceiling for the whole length of the room. I've seen old Scandinavian and American school houses with ovens fitted out this way. There is a limit, however. At some point you have to accept loosing some heat up the chimney as the heat transports the smoke.
You can also attach fins to the stovepipes, increasing the heated area. And there are fans to put on top of the ovens, that start rotating "on their own" (actually from the rising, hot air) and disperse the warm air.
Since the 1980's wood stoves have improved immensely in terms of efficiency, and also pollute a lot less than they used to. There is a ghastly irony in that when people really needed these things they didn't work all that well while today, when wood stoves are not as vital, they're much better.
