We used our wood burning fireplace with insert to heat our house for about 10 years (of the 40 we have been in the house). The cost of wood went through the roof, and the ash dust was an issue for our kids asthma. We are in an all electric house in an area with low electric rates, so just using the furnace ended up being a better option. Last year we had the insert taken out, and an electric simulated fireplace with heater installed. We used it all winter long because it allowed us to just heat the family room, which is where we spent all our time.
