Prevents Air Leakage
Although it is standard procedure to close the damper in a masonry fireplace when it is not in use, what many people don’t realize is that a lot of air escapes the home up through the chimney, even with the damper closed. Dampers rarely have an adequate seal to prevent the heated air in a home from escaping through a fireplace that is not in use. Having a traditional fireplace can be like having a window in your home cracked open year-around. With a fireplace insert, air leakage is no longer a concern. The glass doors form an efficient seal that prevents the back-and-forth flow of air from chimney to the home and vice versa.
Since fireplace inserts are available in EPA-certified wood, gas and electric models, you have a choice of fuel for your fireplace. You can easily convert your traditional fireplace into a more energy efficient and environmentally friendly wood-burning fireplace or choose the convenience of gas, pellet or electric fireplace inserts that are as easy to use as flipping a switch. A thermostat allows you to control the heat and maintain a comfortable room temperature.
