heating with electricity is very inefficient try propane space heaters or kerosene space heater.
They are much safer then they used to be and very efficient. Trying to power an electric furnace is very energy intensive as is just a space heater.
As far as wood stoves you can build a structure then pipe heated water in from the stove and use that to heat the floors and base board heat exchange. I have seen that done the structure is a shed and is connected by insulated pipes, it is pretty efficient.
