According to the National Association of Home Builders, fireplaces rank among the top three features desired by new homebuyers. While popular, the open design of traditional fireplaces causes heated air to be lost through large gaps, making them inefficient as heating sources. The solution for many homeowners is a fireplace insert, which is a shelled, efficient room heater that draft-proofs an open fireplace by keeping heat flowing towards the room.
