What Type of Damper is Best? Pros and Cons of Each
Do you ever think about your chimney damper? Choosing the right one can really make a difference in your home’s comfort, energy efficiency, and chimney protection. On the surface, dampers are simple components, but the type you have/how well it functions plays a huge role in how well your fireplace performs.
The two main options you have are throat dampers and top-mount dampers. Each has its advantages and disadvantages. Here’s what you need to know.
Throat Dampers
Throat dampers are the most common and traditional type. They’re typically installed just above the firebox and operated via a lever or handle.
Pros
They’re affordable and widely available because these dampers have been used for decades, which makes them easy to find and replace.
They’re easy to operate with a simple lever or handle.
Lastly, they are easy to access because they sit above the firebox, making adjustments and repairs convenient.
Cons
Throat dampers are notorious for their poor sealing. Metal-on-metal contact doesn’t always create an airtight seal, which can allow drafts and energy loss.
They’re prone to damage from constant exposure to heat, smoke, and moisture, which can lead to corrosion.
They offer limited protection by failing to keep out rain, debris, and animals.
Lastly, heated or cooled air can escape through small gaps, making them less energy efficient than top-mount dampers.
Throat dampers are best for homeowners who need a budget-friendly option or if they already have a functioning throat damper and need a fast, easy replacement.
Top-Mount Dampers
Top-mount dampers are installed at the very top of the chimney and are operated by a cable or chain that runs down into the fireplace. Experts consider these a modern upgrade and a better option than throat dampers.
Pros
Top-mount dampers provide an excellent seal via a rubber gasket, creating a near airtight closure that can dramatically reduce air leaks.
Because of the tight seal, they’re more energy efficient than throat dampers, preventing heat loss in winter and keeping hot air out in summer.
Top-mount dampers function like a chimney cap and help keep rain, debris, and animals from entering the flue.
They’re more durable because they’re far enough away from the heat, reducing the risk of warping or corrosion.
Lastly, top-mount dampers are low maintenance because they’re resistant to rust and weather-related damage.
Cons
Top-mount dampers cost more to install than throat dampers, which can be too expensive for homeowners on a budget.
They’re also more complicated to install, requiring roof access, which often means you need a professional.
Top-mount dampers aren’t suitable for all fireplace types, like some manufactured or gas systems.
Top-mount dampers are best for homeowners who want maximum energy efficiency, long-term durability, and an extra layer of chimney protection.
So, which one is best? In nearly every case, top-mount dampers are. Their airtight seal, energy savings, and ability to protect the entire chimney system make them the most efficient and durable choice. Most homeowners feel immediate improvements in comfort and reduced drafts after upgrading.
With that said, throat dampers still have their place. If your existing damper is in good shape and you’re not concerned about minor energy loss, it will serve you well for years to come. They’re also easier and less expensive to replace.
