Yes, in most cases, you can remove a fireplace while keeping the chimney. This process requires sealing the chimney at the bottom where it connected to the fireplace and capping it at the top. It is essential to consult a chimney professional or inspection specialist beforehand. They will need to determine if the chimney's structural integrity is sufficient to remain safely in place without the support of the fireplace.

The best location for a wood stove depends on your home's layout and venting options. For optimal heat distribution, a central location on the ground floor, such as the living room, is often recommended. If you have an existing, functional chimney, installing the stove there can simplify the venting process. Alternatively, placing the stove near an outside wall can make it easier to route a new chimney through the roof. For safety, ensure no combustible materials are near the stove. Building codes typically require 20 to 36 inches of clearance between the stove and any side walls.

Some of the reasons a chimney damper won't close properly include shoddy installation, age-related damage, or heavy snow or ice affecting a top-sealing type. Poor chimney maintenance and a buildup of rust, debris, or creosote can also cause dampers to jam. Annual inspections and chimney sweep costs are worth it to help you avoid a damper disaster. 

Wood fireplace inserts produce more heat without replacing the whole system. A fireplace installer can verify that you have a connector and chimney system to fit the wood-burning insert.

Gas fireplace inserts require less maintenance and are an efficient way to produce warmth. Some can also produce heat in the event of a power outage.

Electric fireplace inserts don't have a real open flame, so they produce flames that mimic a real fire surrounded by artificial logs with LED light. Many electric fireplace inserts produce heat from glowing elements while only using electricity.
