The damper is an important component of your fireplace and chimney system. It is a metal flap in your chimney, and the purpose of it is twofold. First, to keep the flow of air that’s coming from the outside from entering your chimney when your fireplace is not in use. Secondly, to allow air in when you’re using your fireplace. Simply put, this important little piece of equipment helps create a draft to make your fire burn more efficiently and keep the smoke out while you’re burning a fire. In addition, stopping cold air and odors from coming back into your home when you’re not using your fireplace.
Dampers are such an important part of your chimney system. However, most people fail to consider the amount of wear and tear the damper takes over a season of using your fireplace. Just using it will cause deterioration! Plus, when you add to that the effects of precipitation, it’s pretty easy to see how quickly breakdown can occur. Also, moisture is released when you burn wood in your fireplace. Unfortunately, as this is sucked up and out of your home through the chimney, it’s inevitable that some hits your damper assembly. Both moisture from fire and outdoor precipitation sneaking in can cause your damper system to become rusty. Not to mention, hard to open and close!
Another thing that can cause your damper system to become damaged, warped, or even stuck open is exposure to heat and ashes. A warped damper system is an inefficient damper system, because it’s impossible for a tight seal to form. Also, if your dampers are made of cast iron or steel, it’s difficult for a tight seal to form as well. And when no tight seal is formed, heat from the house is probably escaping right up the chimney. That can cost you a lot of money in the form of high heat bills.
Lock Top Dampers
So, how can you solve the problem of an inefficient damper assembly? You can look into purchasing a lock top damper, that’s how! A lock top damper is specially designed to seal tightly because it has a rubber gasket. This rubber gasket can form fit to whatever space it’s filling, there are no gaps. This means you won’t be losing heat or cool air from your furnace or air conditioner.
Another advantage of a lock top damper? It’s is mounted right on the top of your chimney, which is the best place for that airtight seal to form. So, you don’t need to worry that it’s hard to open or close; there is a cable that drops down the flue and attaches to a handle. This can be mounted in a reachable place, so that you can easily open and close the damper system.
