I have been heating my house with a factory built fireplace. Overall I probably depend on it about 80% or better. I rarely even turn my heat but I'm sure you can imagine the exorbitant amount of wood/work it takes to maintain a comfortable temperature using this. I am considering the purchase of a wood stove that would give me a decent upgrade from what I am currently using. I am planning to completely remove the existing fireplace but use the existing chimney with a stainless liner. I would lay my own stone rear shield and hearth. I have looked at a variety of used stoves and I feel that given my mild climate (NC) I do not need large stove but would like to be able to sustain a decent overnight burn that could easily be revived in the morning (as opposed to 3 - 4 times per night with my existing fireplace). I am open to suggestions.
