Advantages of a Top Sealing Damper
Around this time of year, the cost of the heating bills always spike wildly. No one wants to be cold during the winter, so sacrificing a few extra dollars to kick up the thermostat often seems worth it at the time. Yet when the bills come, a blanket suddenly sounds like a better choice. For those who rely on a fireplace to provide heat for the home, there are some options for cutting costs. One way to save some money is to utilize a top sealing damper.

The damper in the fireplace is a mechanism that controls the flow of air through the chimney. It is generally made of steel or ceramic to stand up to the heat of the fire and it opens and closes with a handle, pull chain or lever. Most fireplaces utilize the damper in order to vent the toxic fumes from the fire. Therefore, the damper should be open while the fire is burning and until the fireplace has cooled once the fire has been extinguished. Any other time, keep the damper closed to keep the warm air inside the house.
One common type of damper is known as the throat damper, which is located just above the firebox at the bottom of the chimney. These install very easily, so they are very commonly found in many homes. The other type, known as the top sealing damper, sits high in the chimney, and is less frequently seen. However, the top sealing damper does have its benefits.
The way these two dampers differ is based on the draft, or how the air flows through the chimney. Warm air rises, so when the fire starts, the warm air moves up through the chimney. This draws out the smoke and other toxic fumes while also pulling fresh, oxygenated air into the fire from the home, creating a steady flow of air. In a throat damper, the chimney is primarily filled with heavy, cold outdoor air, so the hot air moves more slowly up through the chimney at first. If the initial fire is too large, it could end up filling the house with smoke. On the other hand, the top sealing damper allows the chimney to fill with the warm air from the house prior to lighting the fire. Thus, when the fire starts, the hot air and smoke can move quickly up the chimney. This saves time and fuel when first lighting the fire, making the top sealing damper an easy choice.
