ABSTRACT OF THE DISCLOSURE The invention relates to a fireplace insert having unique characteristics of a fiberglass insulated twin wall construction engineered to work on the principle of air convection. Cold air is drawn into a bottom inlet, circulated through channels between the firebox and an air shroud or air casing, and forced through outlets at the top of the unit back into the room. A controllable damper cuts down the heat carried up the chimney, and an air tight door controls the amount of in-house air drawn to feed the fire, and hence the amount of heat that escapes up the chimney.
