While traditional wood burning fireplaces add charm and ambiance to a home, they don’t provide the most reliable supplemental heating. An open hearth can result in heat loss, pulling most of the warmth out of your home. You may end up with high energy costs every month just to keep a consistent temperature.  

One of the best ways to get more heat from your existing wood fireplace is by installing a wood stove insert. In this article, we’ll explain how wood stove inserts can help your fires burn more efficiently and keep all heat inside your home.  

What is a Wood Stove Insert? 

Wood stove inserts are installed inside of existing masonry fireplaces. They’re steel or cast-iron fireboxes that are “inserted” into your fireplace opening and finished with a decorative surround that covers any gaps.  

They also have sealed glass fronts that extend the life of your fires, allow you to see the flames, and prevent smoke from spilling into your home. 

Wood stove inserts work by drawing air from the room, circulating it around the stove, and then sending out warm air back into the room.  

Most wood stove inserts are EPA certified to meet the Environmental Protection Agency’s standards for 60-80% fuel-efficiency. They’re also typically equipped with features like air control systems to regulate the burn rate and improve combustion efficiency.

How Wood Stove Inserts Prevent Heat Loss 

One of the most common issues with open masonry fireplaces is heat loss through the chimney. Even when your fireplace isn’t burning and the damper is closed, the chimney can still act as a tunnel for cold air to enter your home. 

Here’s how a wood stove insert fixes this problem: 

Sealed Design - Wood stove inserts have airtight doors that prevent drafts. Unlike open fireplaces, which pull warm air from the room, these inserts create a controlled environment that maximizes heat retention. 

Insulated Chimney Liner – Most wood stove inserts require an insulated, stainless steel chimney liner, which improves draft control and prevents heat loss through the masonry.  

Longer Burn Time – Because they’re sealed, wood stove inserts burn longer and more efficiently than traditional wood fireplaces. This reduces the need for excessive airflow and prevents drafts.  

Better Heat Retention – Wood stove inserts distribute heat directly into your home, keeping it warmer for longer. Most inserts also include a built-in fan or blower to help circulate more warmth into the room. 

Benefits of Installing a Wood Stove Insert 

Beyond preventing heat loss, wood stove inserts provide a few notable advantages that make them a smart investment:  

Lower Heating Costs – Wood stove inserts burn for much longer than traditional wood fireplaces and use less fuel. They allow you to get more heat from your fireplace, while reducing your overall heating expenses.  

Eco-Friendly – Many modern wood stove inserts are EPA certified, producing fewer emissions and protecting your air quality.  

Extra Safety – Wood stove inserts have enclosed designs that prevent sparks and embers from escaping. They also ensure efficient combustion to reduce dangerous creosote buildup. 

Enhanced Aesthetic Appeal – Available in a variety of styles and finishes to match your space, wood stove inserts allow you to upgrade the look of your fireplace, while maintaining and cozy, classic atmosphere.  

Increased Home Value – A high-efficiency wood stove insert can significantly boost your property value and make your home stand out to potential buyers.
