Save Money & Energy With A Top-Sealing Damper

No one likes getting massive heating bills or wasting energy while heating or cooling their homes, but your fireplace could be causing you to do both.

Do you notice cold or hot air (depending on the season) coming in through your fireplace opening? Does it seem like your heat or AC has to run constantly in order to maintain a comfortable temperature in the room your fireplace is in? Your damper might be the problem.

You see, traditionally, dampers — which are really just fireplace components designed to close off the flue when the fireplace is not being used and open it up when the fireplace is being used — have been constructed of metal and installed down in the throat of the chimney. The problem with this is that these throat dampers rust into place, accumulate creosote deposits, and, even when clean and in good working order, provide a metal-on-metal seal that’s far from being airtight. That’s why, even when your damper is closed, you could feel outside air coming down into your home through your fireplace opening or lose conditioned air through your chimney. Thankfully, there’s a way to put a stop to this energy and money waste that’s both effective and affordable: install a top-sealing, energy-top, or seal-tight damper.

How Is A Top-Sealing Damper Different From A Throat Damper?

Throat dampers are metal dampers installed just above the fireplace, but top-sealing dampers are different in terms of both material and placement. These dampers are installed at the very top of the chimney flue, like a chimney cap, and when closed, a rubberized gasket seals off the flue. That means:

  • No energy waste or conditioned air loss
  • No water, animals, or debris in the chimney flue
  • No downdrafts
  • No components to rust into the open or closed position

Are Top-Sealing Dampers Easy To Use?

Worried about how hard it might be to open and close a damper that’s located at the top of the chimney? No need. Like a throat damper, your energy-top or top-sealing damper will have a chain or lever that makes it easy to open and close. And since it’s located where your cap would normally be, with a top-sealing damper, you actually get one product that does the job of two.
