Chimney Scientists installs high-efficiency wood inserts for homeowners across the Greater Philadelphia area, including Montgomery, Bucks, Chester, and Delaware counties, along with Monroe, Lehigh, and Carbon counties in the Poconos.

What Is a Wood-Burning Fireplace Insert?

A wood-burning fireplace insert is a self-contained, high-efficiency firebox designed to be installed directly into your existing masonry fireplace or prefab fireplace. These inserts transform inefficient open fireplaces into powerful wood-burning appliances, providing better heat output, cleaner combustion, and energy savings.

Wood inserts are made from durable steel or cast iron and feature insulated glass doors, built-in fans, and air control systems to maximize performance. They’re ideal for homeowners who want the ambiance of a real fire with the benefits of modern heating technology.

Benefits of Installing a Wood Fireplace Insert

Upgrading your old fireplace with a wood insert provides a wide range of practical and aesthetic benefits:

  • Greater heating efficiency: A traditional open fireplace may lose up to 85% of its heat. Inserts capture and circulate heat more effectively to warm your living space.
  • Lower heating bills: Fireplace inserts are more cost-effective than open fireplaces. They burn less wood and retain more warmth, reducing reliance on your central heating system during colder months.
  • Cleaner burn: EPA-certified inserts produce far less smoke and creosote than older systems, keeping your chimney cleaner and your air safer.
  • Enhanced appearance: Modern inserts offer sleek designs that complement both traditional and contemporary interiors.

With a professional wood fireplace insert installation, you’ll enjoy more heat, fewer emissions, and a cleaner home.

Wood Stove Insert vs. Traditional Fireplace

A wood stove insert is significantly more efficient than an open fireplace. While a traditional fireplace radiates some heat into the room, most escapes through the chimney. In contrast, an insert uses combustion chambers, air control, and fans to retain and distribute heat efficiently.

Here are some key differences between the two:

  • Efficiency: Inserts can achieve efficiency ratings of 60–75%, compared to under 15% for open fireplaces.
  • Safety: Sealed systems reduce the risk of backdrafts, sparks, and excessive creosote buildup.
  • Control: Adjustable air controls let you manage heat output, burn rate, and airflow with ease.

For homeowners who prefer freestanding models, we also offer full wood stove installation.

How Efficient Are Modern Wood Inserts?

Efficient wood fireplace inserts use advanced combustion technology to get the most heat from every log. Many models are EPA-certified and designed for long burn times, allowing you to enjoy hours of warmth from a single load of wood.

Features that boost efficiency include:

  • Airtight doors to contain heat
  • Secondary combustion systems to burn smoke and gases
  • Built-in blowers that distribute warm air throughout the room

Depending on the size of your home, an insert can heat up to 2,000 square feet or more—perfect for zone heating or reducing dependence on your furnace.

We didn't know what was wrong with our chimney, but could see moisture was damaging the plaster in the ceiling around it. We consulted a roofer who said the issue was the flashing (on the roof just above the room where damage was visible). New flashing had absolutely no effect. Talked to another roofer who admitted he was stumped and recommended a company called "Chimney Scientists". Best recommendation EVER. The Chimney Scientist inspector recognized the problem immediately: unfortunate repairs in the 1980s to this chimney built in 1900 used a modern type of mortar (Portand cement) that trapped moisture inside our chimney, forcing water out through brick (and then into surrounding ceiling plaster). This past week Chimney Scientists rebuilt our chimney in the top floor of our house and up through the roof using historic lime-based mortar. They found reclaimed brick that closely matches our original brick for the exposed chimney inside the house. Above the roof, they used new brick that will resist the elements for a long, long time. End result: a gorgeous, healthy chimney inside and out. During the job, they provided thorough protection around their work area. At the end of the job, they cleaned up to perfection. All along the way, they cheerfully provided crystal clear and detailed explanations. Maybe best of all: they LISTEN. Whenever we had any concerns or questions, we were heard and any needed adjustments were made right away. The name Chimney Scientists isn't just great branding: these guys really DO understand the science behind chimneys and they take great pride in skillfully solving chimney problems. 10 stars out of 5.
