Okay, I have a wood burning stove and a fireplace, and up here in the Mountains of East Tennessee, it does get damn cold.
I usuallycut my own, and its USUALLY oak and hickory, although Hickory is best to sell to a BBQ place for $100 a rick (i forget how may ricks in a Cord, but we use Ricks for our measurement) and a rick of Oak is about 45, and they burn the same.
For me, to use electric heat is 4 times MORe expensive than burning. I built my own house by myself, and insulated the bastard very well, so my house is always toasty, so I dont know your exact situation in that regards, but you should still come out ahead burning wood.
Is it a real fireplace, or one of them sorta fake ones, that you can burn wood in, but they throw shit for heat?
Also remember, fireplaces only heat what you can see from them, unlike a wood burning stove. They can throw a LOT of heat, but generally not in the same way a stove does.
Open floor planned house?
