Fireplace Insert

A fireplace insert is a closed combustion unit specifically designed to be retrofitted into an existing open fireplace, dramatically improving heating efficiency and reducing heat loss. Where a traditional open fireplace may lose 80 to 90 percent of its heat up the chimney, a quality insert can capture and redirect much of that energy back into the room. Inserts are available in wood-burning, gas, pellet, and electric configurations to match different homeowner preferences and fuel availability. The installation of a fireplace insert transforms an underperforming masonry fireplace into an effective heating appliance while preserving the visual appeal of the original fireplace surround and mantel. Modern inserts feature large glass doors for fire viewing, built-in blower systems for enhanced heat circulation, and tight-fitting construction that prevents room air from escaping up the chimney. They represent one of the most cost-effective ways to upgrade an existing fireplace without full reconstruction.

Placement & Usage Tips

Fireplace inserts must be properly sized to fit the existing fireplace opening. Professional installation is recommended to ensure correct venting through the existing chimney and proper sealing around the unit.

💡 Pro Tip

When choosing an insert, have your existing chimney inspected first to determine what type of liner will be needed. A properly sized insert with a full chimney liner will deliver the best performance and safest operation.
