Did You Know?
1. The concept of fireplaces dates back to ancient Rome, where they were used not only for heating but also for cooking and keeping food warm.
2. Did you know that even when a fireplace isn’t in use, it can still draw warm air out of a room? This is due to the stack effect, where the difference in air pressure between the inside and outside of a house creates a natural airflow.
3. In the early 19th century, some fireplaces were equipped with ingenious contraptions known as fire screens. These screens were made of wire mesh and placed in front of the opening to prevent sparks from flying out and causing accidents.
4. Contrary to popular belief, closing off a fireplace entirely can lead to moisture-related issues, such as mold and mildew growth. To avoid this problem, it’s recommended to keep a small vent open to allow proper airflow.
5. If you’re looking for an eco-friendly alternative to closing off your fireplace, consider installing a fireplace insert. These energy-efficient devices fit into existing fireplaces, significantly reducing heat loss and improving indoor air quality.
Reasons For Closing Off A Fireplace
Fireplaces have long been considered a luxurious addition to any home. However, as the years have gone by, homeowners are beginning to question whether the benefits of owning a fireplace outweigh the required maintenance and upkeep. One of the main reasons for closing off a fireplace is that it simply requires a lot of work that may not be worth it if the fireplace is hardly used. From cleaning out ash and soot to ensuring the chimney is in working order, owning a fireplace can be a time-consuming and labor-intensive task.
Furthermore, modern heating systems have significantly improved over the years, making traditional fireplaces less essential for heating a home. With the availability of central heating and other energy-efficient options, many homeowners find that they rarely use their fireplaces for warmth. As a result, the fireplace becomes more of a decorative feature or simply an unnecessary energy drain. Considering these factors, it is no surprise that more and more homeowners are opting to close off their fireplaces.
Sealing Off The Fireplace Opening And Flue System
Closing off a fireplace involves sealing off the fireplace opening and flue system to stop the flow of air to and from the home. This process can be done either temporarily or permanently, depending on the homeowner’s preference and the intended usage of the fireplace.
To seal off the fireplace opening, one method involves using a fireplace cover or magnetic cover that fits over the opening. These covers are made from insulated material and are designed to prevent the air from escaping through the chimney. They can be easily installed and removed when desired. Alternatively, a more permanent solution involves installing a sheet of fire-resistant material over the opening, such as cement board or metal, which can be painted or decorated to match the room’s aesthetic.
When it comes to sealing off the flue system, there are a few options to consider. One approach is to install a top-sealing damper, which is a device that sits at the top of the chimney and can be opened or closed to control the airflow. Another option is to install a chimney cap, which covers the top of the chimney and prevents debris or animals from entering while still allowing some airflow. These methods can significantly reduce the amount of air that flows in and out of the chimney, improving energy efficiency.
Impact On Energy Efficiency
The flow of air through the chimney can significantly impact a home’s energy efficiency. Even with a damper, chimneys can let warm air out and cold air in, or vice versa in the summer. This airflow can cause a draft, resulting in the need for additional heating or cooling to compensate for the loss. By closing off a fireplace and sealing the flue system, homeowners can effectively prevent this unwanted airflow, leading to improved energy efficiency throughout the home.
Additionally, closing off a fireplace can help prevent air leakage in older homes. Older fireplaces may not have been built with energy efficiency in mind, allowing air to escape through gaps and cracks around the fireplace. By sealing off the fireplace, homeowners can minimize these air leaks and create a more airtight living space, reducing energy waste and ultimately saving on heating and cooling costs.
Airflow Issues In Chimneys
Chimneys are an essential part of facilitating the flow of air, but in certain scenarios, they can cause problems within the home. Apart from the previously mentioned concerns about energy efficiency, improper functioning can also allow smoke and pollutants to enter the living space, posing a health hazard, especially for those with respiratory sensitivities.
One common issue related to chimney airflow is the backdrafting of exhaust gases from heating systems. When a fireplace is not being used, the air pressure inside the home can force these gases back into the living spaces through the chimney. This results in increased levels of carbon monoxide, jeopardizing the safety of the household. However, homeowners can mitigate these airflow issues and ensure the safety of their living environment by simply closing off the fireplace.
- To facilitate the flow of air, chimneys are designed but this can sometimes lead to issues within the home.

Temporary Solutions For Closing Off A Fireplace
For those looking to save on heating bills without completely closing off their fireplace, there are a few options available:
-
Temporary Fireplace Screens or Curtains: These screens can easily be installed and removed, providing a barrier between the fireplace and the room. They allow you to preserve the functionality of the fireplace while still preventing excessive heat loss.
-
Draft Stoppers or Draft Snakes: Another option is to use draft stoppers or snakes, which can be placed at the base of the fireplace opening. These prevent drafts from entering the room and help to conserve energy.
These temporary solutions offer a convenient way to close off the fireplace during colder months and conserve energy. However, they can be easily removed when the fireplace is desired for use during special occasions or for decorative purposes.

Frequently Asked Questions
Can you just close up a fireplace?
Yes, it is possible to close up a fireplace by covering or sealing the opening with either brick or drywall. This can be done either as a DIY project by building a drywall fireplace cover or by hiring a professional to assist you. Some drywall fireplace covers are designed to function like a plug, allowing for easy removal from the opening whenever desired. By taking these steps, you can effectively eliminate the fireplace and create a sealed space in your home.
Do you have to close a fireplace?
Yes, it is generally advised to close the damper of a fireplace when it is not in use. This is because an open damper can result in warm air from inside the house escaping, leading to energy loss. However, if you have gas logs in your fireplace, it is crucial to keep the damper open to prevent the buildup of dangerous carbon monoxide gas. By doing so, any potential carbon monoxide is safely vented out of the house, ensuring the safety of the occupants.
Is it OK to block up a fireplace?
Blocking up a fireplace may seem like an easy solution for those looking to reduce drafts or save on heating costs. However, it is important to consider the potential consequences. Sealing off a fireplace and chimney may lead to the accumulation of water inside the flue, causing condensation problems. Even with a supposedly airtight blockage, hidden water issues can still arise. Therefore, it is not advisable to block up a fireplace as it can result in unforeseen water-related complications that may be difficult to rectify.
Why do people close off fireplaces?
Closing off fireplaces serves two main purposes. Firstly, during the hot summer months, closing the damper prevents cool, air-conditioned air from escaping outside. This helps to maintain a comfortable indoor temperature and reduces the strain on the air conditioning system, thereby promoting energy efficiency. Secondly, in the winter, when the fireplace is not in use, a closed damper prevents cold air from entering the house. By blocking the entryway, it prevents drafts and ensures that the warm air produced by the heating system remains inside, providing thermal comfort and reducing heating costs. Overall, closing off fireplaces offers effective insulation and contributes to maintaining a comfortable indoor environment year-round.
