Fireplace Inserts explained
Fireplace inserts are like modified wood stoves that fit within the existing firebox of a masonry fireplace. Inserts are used to convert inefficient masonry fireplaces into effective heating systems. Fireplace inserts consist of a firebox surrounded by a steel shell. Air from the room flows between the firebox and shell to be warmed.
The outer shell ensures that most of the heat from the firebox is delivered to the room instead of being released into the masonry structure. A decorative faceplate covers the space between the insert body and the fireplace opening.
When done correctly, insert installation should be considered permanent. Installed correctly, the insert should not need to be removed from the fireplace for many years. The liner and all the hardware supporting it is corrosion-resistant stainless steel. We use only stainless steel chimney liners.
Where the liner passes through the fireplace throat (the damper, smoke shelf area) it should be sealed to the masonry. This area is stuffed with mineral wool or with a sheet metal plate. A good seal in this location prevents cold air around the liner from entering the room, therefore making it more efficient.
What are the benefits?
The main benefit of a wood fireplace insert is that it gives you the beauty of an open fireplace with the performance of a state-of-the-art wood stove. The efficiency rating for wood fireplace inserts generally runs around 50 percent (Kaufman) – less than gas inserts. This rating is still much better than traditional fireplaces.
The disadvantage of burning wood is the emissions. Wood smoke is wasted fuel that sticks to your chimney as creosote (which is combustible) or is released as air pollution.
