What is a damper?

Chimney Damper Diagram

A fireplace damper is normally located at least 8 inches above the firebox opening. The damper acts as a door separating the chimney and the inside of your home, allowing the smoke to exit when open. When the damper is closed, it prevents downdrafts from entering your home.

Are you aware of what kind of damper you have on your chimney? If not, it is worth it to find out because your leaky throat damper could be costing you hundreds of dollars a year in energy loss. Read more below to find out why and what you can do to prevent this.

Problems with Traditional Throat Dampers

Traditional dampers were designed for times when energy was not nearly as expensive as today. These throat dampers cause several problems because they are made completely out of metal. Throat dampers are sealed by metal to metal closure, which allows hot and cold air to leak through. Due to this inefficient seal, your air conditioner may need to work harder and longer to get to the temperature you have set and that can run up your utility bill. Allowing air into your chimney also interferes with the temperature of your flue liner which makes starting a fire difficult because of the cold air rushing down the liner. The air can then push smoke and ash into your home, and no one wants that! Traditional dampers also add no protection from outside debris entering the throat of your chimney. Any blockages or clogs can cause smoke and dangerous gases to enter your home.

Advantages of A Lock-Top Damper

Lock-Top dampers use a silicone rubber gasket for a perfect seal that allows no air to seep through.  These dampers block rain from entering your chimney as well, so you do not have to worry about any corrosion is your flue liners or chimney throat.  Adding this damper greatly extends the life of your chimney and increases its effectiveness. By being placed on the top of your chimney, these dampers also add protection against debris and any pesky critters that try to burrow in your warm and homey chimney. Not only do Lock-Top dampers save you money on your utility bill, but they also prevent future damages that can come from only having a traditional throat damper installed. So, say yes to saving energy and money by calling your top-rated local chimney sweep company to come to inspect your chimney and install one of the best energy-saving fireplace dampers the market as to offer!
