A Top Sealing Damper Can Save Energy

Most fireplaces have what is called a throat damper. It is named that because it sits in the “throat” of the firebox, leading up to the flue. Although many throat dampers work just fine, a top sealing damper (which sits at the top of the flue and seals the entire flue off so nothing can enter from the top) can outperform a throat damper any day. The placement of the top sealing damper allows the air in the flue to heat up in the winter and cool in the summer, and can significantly cut down on conditioned air loss. The result: energy savings!

Heating Up a Room Full of Ice

Another way of looking at it is this: imagine heating up a room with a tube full of ice in the middle of it. That ice is the cold air that is between the throat damper and the top of the flue. You are continually fighting to heat it. In the summer you are trying to cool it. Getting a top sealing damper seals this space off at the top and doesn’t let the outside air, hot or cold, invade that space. Additionally, replacing a broken or damaged damper can greatly improve the operation of your fireplace.

The truth is, every fireplace should have a damper. A damper of any kind can cut down on temperate air loss.

We offer top sealing dampers because they:

  • Eliminate down drafts
  • Seal out the rain (which can deteriorate the inside of your chimney)
  • Prevent nesting birds, squirrels and raccoon’s from entering your chimney
  • Plus, you get the potential energy savings!

If your fireplace does not have a damper or tight fitting glass doors,  you could be pumping money up your chimney and out of your pocket!
