Why you should install a top-sealing damper

Almost all fireplace dampers are the same, a cast-iron contraption located at the top of the firebox. Many homeowners assume that these dampers are the only type. However, there’s another option and you may want to consider it. Here’s what you need to know about chimney dampers and why you should install a top-sealing damper in your home.

The Problem With Traditional Chimney Dampers

Most chimney dampers use a basic technology. A metal ring or exterior surrounds the opening of the chimney flue at the top of the firebox. A flap either folds or twists to fit into that damper when it is closed and your fireplace is not in use. The problem with these types of dampers is that they are highly inefficient, and they become burdensome over time.

Due to the extreme heat of the fireplace, metal fireplace dampers warp over time and fail to form a tight seal. The warping can also impact the mechanics of the damper, causes it to get stuck or make it difficult to open or close. Once your chimney damper fails, your chimney lose a significant amount of air when not in use. This also makes it easier for cold drafts to make their way down your chimney.

The Solution to Inefficient Dampers: Top-Sealing Dampers

If your traditional throat chimney damper has failed or is allowing cold drafts into your home, the best solution is to get a top-sealing chimney damper. A top-sealing damper is fitted to the top of your chimney, rather than placed inside. These dampers feature rubber gaskets to allow the damper to seal off the chimney entirely when your fireplace is not in use.

When you install a top-sealing chimney damper, a cable runs down the interior of the chimney. The damper is opened or closed with the pull of a chain or a lever. You’ll also notice that warm air is sealed inside your home, while water and cold drafts will never find their way in again. It will also help your chimney flue to block off wild animals and debris!

How To Make Your Chimney More Efficient

Was your chimney working at its best this winter, or did you have problems with cold drafts or smoke finding their way back into your home? If your chimney left something to be desired, now is the time to make upgrades. If you are ready to increase your chimney’s efficiency this summer, there are several ways you can improve its function.

Chimney Efficiency - Sacramento CA - A to Z Chimney Services

One of the biggest chimney’s inefficiencies comes when your fireplace isn’t in use. Hot air from your home rises up and out of the chimney.  In the same way, cold burst of air can blow down through the chimney and into your home. Up to 8 percent of your home’s heat can be lost through the chimney, which means your chimney could be costing you money. Your damper is meant to block air exchange through the chimney when the fireplace isn’t in use. Most dampers warp over time and fail to seal off the chimney entirely.

A top-sealing damper can solve the problem. A top sealing damper is installed at the very top of your chimney. When closed, it seals off the flue entirely. This prevents downdrafts from entering your chimney and warm air from rising out of your home. If you are looking to make your chimney — and your home — more efficient, a top-sealing damper can help.

Replace Your Chimney Cap

Your chimney cap also can help to stop drafts from entering your home through your chimney. Many homes are equipped with cheap, builder-grade chimney caps that corrode rapidly or are easily knocked out of place. Installing a new chimney cap that’s made from a strong material, like stainless steel, can help make your chimney more energy efficient. The strong material helps block downdrafts of cold air.

Repair Chimney Damage

Cracking, crumbling or otherwise weakened masonry can also decrease the efficiency of your chimney. Cracks in the masonry allow air to escape through the walls of the chimney. Having chimney masonry repaired during the summer months can help keep your home warmer, and lower your energy bills, next winter.

Have Your Chimney Relined

If your chimney is drafting inefficiently, causing smoke to come back into your home, your chimney liner could be to blame. Cracks or uneven construction can cause smoke to draft upward inefficiently and ineffectively. Or, your chimney liner could be the wrong size to efficiently draw smoke out of your fireplace. Having your chimney liner repaired or relined could have your chimney working efficiently to keep smoke out of your home.

If your chimney wasn’t working as efficiently as it could last winter, call A to Z Chimney Services today! We can install a new top-sealing damper or chimney cap, repair chimney damage or reline your chimney.

Why Do I Need to Know?

Chimneys might look perfect on the outside but a lot of hazardous and unwanted problems can occur on the inside; molds, soot and creosote build-up, blockages, etc. We think those reasons are enough for you to take the time to learn about the most basic and fundamental parts of your chimney.

Basic and Fundamental Parts and Functions

These are some of the parts you need to pay close attention to. First is the chimney crown and chimney cap which is considered the first line of defense of your chimney. It protects your chimney from any blockage and prevents water from seeping into the inside of your chimney.

Second, the flue and the flue liner which should be in excellent condition. This is where the smoke of harmful gases from combustion passes through. This also eliminates possibilities of flammable debris from gathering. You have to be mindful of creosote that might be building up in the flue walls though.

The smoke chamber is just as important as well. This is the part is found above the fireplace and just beneath the flue. It is where by products are compressed into a smaller area to prevent draft from happening and allows smoke to escape via the flue.

And last but not the least is the chimney damper. This will help regulate the energy used or unused during and after using your fireplace or wood stove. It is used to close the chimney to prevent heated air from being lost up the chimney.
