I’m the gas fireplace is legit, but the stove can be replaced with butane cans.
I’ve been without heat in the Midwest in the winter (furnace died in a rental). It’s actually not that hard to keep a single room or two warm enough with simple painters plastic. Staple/tape them up and hang out in that room. By limiting airflow (don’t entirely cut off outside oxygen), you keep an amazing amount of heat in the space. Not warm, but certain manageable with a few layers of.
Propane heaters can also be used relatively safely.
But if you can’t safely get out of the house to go buy the nonexistent butane or propane heaters at the store because all the roads are frozen over and all the stores are closed, then that idea isn’t going to help you very much.
