Eddie:
Think about the possibility of a gas (either natural or propane) stove.
Sure, you don't get that "free" firewood, but you also don't get the dirt, bugs, and work of cutting, splitting and hauling it, and, best of all, you don't have ashes to deal with.
I heated exclusively with wood for 25 years, and in my new house opted for one propane fireplaces, and one freestanding propane stove.
A wood fireplace is a huge source of dust & dirt from ashes, and the smoke that inevitably gets back into the room is a nasty bit of indoor air pollution -- worse for you and your family than any smog.
The other thing to think about is that with a house your size, bigger is not better with fireplaces. The heat from a fireplace will quickly drive you out of the room it is in.
Just to give you an idea, the study in our new house in Oregon is about 260 square feet. I deliberately bought one of the smallest freestanding propane fireplaces/stoves I could find for it. The rating is that it will put out between 6000 and 14,000 BTU/hour. I turn it down to the lowest possible setting and it heats the study to 72 to 75 degrees with the outside temperature in the high 20s to low 30s.
We have heat pumps for the whole house, but the study is on a completely separate zone from the rest of the house with its own thermostat, so this is with no heat at all from the heat pump.
When I cut down trees on the property, the branches go into a burn pile and the trunks/major limbs are taken away by someone who will do it free for the wood.
