The main thing that one should do to make sure that heat is not being lost through the chimney of a fireplace is to always close the damper when the fireplace is not in use. In addition, you can also use a fireplace door or cover to prevent additional heat loss.
You can improve the efficiency of your fireplace by adding insulation around the firebox and chimney to reduce heat loss and ensure more heat is directed into your home.
When a fireplace is not being used... glass doors are not a good way to stop cold air from exiting the chimney. The first thing that needs to be done is the fireplace damper should be closed to prevent this heat loss. If the damper is not-functional or absent a chimney balloon or chimney top damper can be installed to stop the heat loss.When there is a fire in the fireplace...Fireplace glass doors reduce the amount of already heated interior air that the fireplace has access to. So it does slow down the inside heated air from being cast up the chimney with the fires combustion heat, but glass doors do not stop this heat waste completely. Fireplace glass doors also inhibit the only usable heat the a fireplace produces (radiant heat) from coming into the living area. Standard open fireplaces and fireplaces with glass doors are notoriously inefficient at heating the home. According to the US Department of Energy using a fireplace in the winter will actually make your heating bill go up by 10% on average.
I professional "Chimney Sweep" can help you. There is an additional advantage of a professional doing this task, if this is in a new-to-you home; they will check your chimney and fireplace for potential problems, such as cracks in the firebox, bad damper, chimney problems inside and out etc. If you are going to do this task there are chimney brushes that can be purchased at "big box stores" just make sure you measure your chimney diameter and know if it is round or square. Make sure you close off the fireplace as there will be significant soot, plastic sheets, taped around the edges of the fireplace will reduce most of the soot generated. Clean the fireplace last. Be careful of the vacuum you use as the soot can travel through and be exhausted into your room, some shop-vac's will cause more problems than you can imagine.
To effectively insulate a fireplace and improve energy efficiency while reducing heat loss, you can install a fireplace insert, seal any gaps or cracks around the fireplace, and use a fireplace door or cover when not in use. Additionally, consider adding insulation around the chimney and flue to further prevent heat loss.
I have the same question! Just had my chimney cleaned and the guy said there was no scientific evidence that it helped. For what it's worth, last years chimney cleaner told me to do it because it just might help.
To shut down a fireplace at night and minimize morning odors, first ensure the fire is fully extinguished by allowing all logs and embers to burn down completely. Close the damper to prevent drafts and keep odors from entering the home. Additionally, consider placing a fireplace screen or glass doors to contain any residual smells. Lastly, regularly clean the fireplace and chimney to reduce lingering odors over time.
To reduce the chance of fire from materials rolling out of the fireplace, the floor in front of the fireplace should be a non-combustible material, such as brick, stone, concrete, slate, etc.
I have worked with fireplace chimneys that are tapered. They work great. The tapering takes place in the top 2 to 3 feet of the top and, if memory serves me, it is roughly 75%. Chimney pots also reduce the cross-section of the flue but nowhere near as much. Chimney pots used to be installed to solve smoke problems. Today they are installed because people like the way they look. If someone could explain to me why they work, I'd be most appreciative.
Chimney liner is a lining put in your chimney to reduce carbon build. It not only helps the draft it reduces the chances of fires occuring. This can be bought online or by a specialist.
A chimney cricket is a sloped structure added to a roof upstream of the chimney to divert rain water away from the chimney. They are installed to reduce the amount of rain water that may enter the house if the sealing around the chimney fails or is less than perfect.
To reduce the amount of smoke leaving a chimney, ensure proper air circulation by opening a window or door in the room, maintain a hot and clean-burning fire, use dry and seasoned wood, and have the chimney cleaned and inspected regularly to prevent blockages. A chimney cap can also help improve airflow and prevent downdrafts.
Anthracite has a higher carbon content and burns cleaner with less smoke and ash compared to lignite. It also produces more heat energy, making it more efficient for heating purposes in a home fireplace. Furthermore, anthracite has a longer burn time and produces less creosote buildup, which can reduce the risk of chimney fires.
