I have a storey n half house naturaal gas heat , in a post SHTF living in Canada I need heat in winter, generator will run furnace , kerosene and propane heaters but that will not last long also eats up too much oxygen. When we bought the house there was a old wood burner fire place and rotted chimney metal for insurance reasons I took it out and filled in wall. I was looking at my electric stove and thinking I could Mcgveyer it to a wood burner to heat a couple of rooms and cook on if the hydro aint comming back on anyways. Chimney has stainless liner I could remove with other duct work ? As of now I would rather spend money on other preps wood stove not in budget.
