Energy Efficient Top-Sealing Dampers

Wondering why your energy bill is so high every month? Looking for easy ways to save on energy costs? If your home isn’t outfitted with a top-sealing damper, your drafty chimney may very well be to blame for your excessive energy spending. The good news is that this is an easy, affordable fix—much easier on the wallet than putting in all new windows or insulation—and you’ll reap the financial rewards immediately.

In the past, dampers were made of cast iron and located in the throat of a fireplace. They were infamous for leaking. Studies have shown that even modern throat dampers can leak up to $200 in heating and cooling costs per year. And that’s a new damper; just imagine how much money an old-fashioned chimney damper eats up annually.

Pozzi Chimney Sweep proudly uses Lock-Top Energy Saving Dampers on our chimneys. The red rubber gasket on this damper seals tightly to keep your heat and air in your house where it belongs. These dampers are made of cast-aluminum and stainless steel and mount on top of your chimney. The pop-up lid assures that maximum flue size is maintained. Lock-Top Energy Saving Dampers are easy to use, operating from inside your firebox. A cable drops down the flue and attaches to a handle that’s easily reached for convenient opening and closing.

This was a tough job for these guys. They did a fine job for us. I must rate it as excellent for sure. My only regret is that I did not do this 20 years ago.
