What is a Chimney Damper?
A device located above the firebox that regulates chimney airflow is called a damper. It can be either manually or automatically operated, allowing you to control how much air reaches the chimney. Dampers, that prevent heat loss while not in use, are made of materials like cast iron or stainless steel. This helps boost efficiency. Maintaining the damper correctly is essential to ensuring both safety and best performance.
Traditionally, dampers are placed in the throat of the chimney. However, a lot of homeowners are choosing to add dampers that seal on top. Homes will continue to be warmer in the winter and cooler in the summer because of its placement at the very top of the chimney, which improves energy efficiency. Additionally, it shields the flue from trash, wind, rain, snow, and small animals.
The Operation of a Chimney Damper
The chimney damper is opened and closed using a handle, rotating style screw, or pulling chain. When a damper has a handle, it could also have locks that let you open or close it partially at certain angles. You may regulate the fire’s strength and let fumes and smoke escape the house by keeping the damper slightly open. Up to 80–90% of the heat produced by a fireplace flame can escape up the chimney, something you might not be aware of. One way to reduce heat loss is to adjust the damper.
Which are the types of Chimney Damper?
The two most common types of dampers are throat dampers and top-mounted dampers. Let’s know more about them as under:
Throat Dampers
Throat dampers are traditionally installed in the “throat” of the chimney, directly above the fireplace. They are typically made of metal and run on a pivot point or a pulley system. This sort of damper is operated manually, typically via a handle or lever that opens and shuts the damper plate.
Top Mounted Dampers
Top-mounted dampers, as compared to throat dampers, are located near the very top of the chimney. You regulate them with a metal cable that dangles down the chimney. The dampers seal entirely and give a very tight seal. They’re also simple to install and help you conserve electricity. People frequently use these in new construction and may even add one to their chimneys even if they currently have a throat damper due to the increased energy efficiency they give. The top-mount damper is a more appealing, more affordable solution for fireplace dampers because it functions as both a throat damper and a chimney cap.
What Is the Function of a Chimney Damper?
By regulating the amount of airflow through the chimney, a fireplace damper controls the fire. A sealed damper will let in less oxygen, which might lead a fire to starting slowly or going out completely. Most people are ignorant of the fact that fireplaces need air to function. Fuel and oxygen are required for a fireplace to burn. In the absence of one of those components, the fire either reduces or goes out completely. A chimney damper is usually composed of metal and has a high melting point.
What are the benefits of a Chimney Damper?
It serves numerous benefits that allow the optimum functioning of the chimney. Let’s explore a few of them as under:
- Enhances the quality of indoor air
An open damper will allow oxygen to enter the fireplace and keep the fire burning as you use it for heating your house during the winter. Additionally, it protects the fireplace’s exhaust from coming up into your living area by allowing it to go out the chimney and up the flue. It could be difficult to start a fire and it might burn out rapidly if the damper is broken or doesn’t open fully. Additionally, it may produce more smoke and creosote, which lowers interior air quality and raises the risk of carbon monoxide poisoning and fire.
- Fire Intensity controlled
Additionally, chimney dampers may help in managing the overall intensity of your fire. You can directly impact the fire’s power and intensity by changing the damper, which will alter the amount of oxygen supplied to the flames. Reduced airflow from a partially closed damper results in a smaller flame and a slower burn rate. On the other hand, when the damper opens up, airflow is increased and the fire becomes hotter and more vigorous. Not only does proper damper management control the intensity of the fire, but it also guarantees improved heat output and more economical fuel use.
- To reduce the cost of utilities
Fuel is used more effectively when a damper is used properly. By doing this, the effort and costs associated with gathering and storing fuel are minimized. Less air is wasted when the damper is closed while the stove or fireplace is not in use. This reduces the expense of cooling your home. During the night, you can maintain a fire in your stove by using the damper. Consequently, relighting a new fire requires less time and effort, and fuel is saved.
- Saving from water damage
A chimney damper can help safeguard your house from water damage when it is closed. Without flue dampers, a chimney could allow rainfall, snow, and other pollutants to enter through the walls or roof, forcing expensive repairs. You could reduce the chance of moisture entering your house and causing degradation by installing a chimney damper and making sure it’s managed properly. To further guarantee that the damper works correctly and protects your property against water-related damage, having proper chimney damper maintenance is recommended.
