Do you have an actual wood stove, or just a fireplace?
Our house is 1200sf, and we use a proper wood stove downstairs, and what we call a ‘wood insert’ upstairs. (Like a wood stove built into an old fireplace.)
Even then, it can be hard to manage the heat sometimes.
We have two “certified” wood stoves, but the wood we have to burn is 5 years old and has relatively few BTUs left in it. It produces prodigious quantities of ash but very little heat. What is more, I will not leave the house once a fire is lit. Too many homes have burnt down that way. Our home is two stories. In my current condition it is difficult to schlepp firewood up two flights of stairs from outside around the corner.
