Gas fireplace insert vs. house heat
We have a natural gas forced-air furnace system (new-ish) heating our 100-year old house. The walls of the house is pretty much all insulated but it doesn't maintain consistent temps due to old windows and doors. The first two floors (excluding the unheated attic) are about 3200 square feet, of which about 800 is the kitchen/family room. Since we spend 90% of our time in the kitchen/family room, does it make sense that we would save heating costs by putting in a natural gas fireplace insert in place of the wood burning fireplace we have in their now. Obviously, we're not changing fuels - both the furnace and the fireplace would be natural gas. It's just that it seems we could heat the family room/kitchen without heating the rest of the house as much. Is this right or wrong thinking?
