Professional Gas Fireplace Inserts & Installation in the Greater Philadelphia & Pocono Areas

If your wood-burning fireplace is drafty, inefficient, or rarely used, upgrading to a gas fireplace insert is one of the easiest ways to add warmth and value to your home. Whether you’re looking for energy savings, cleaner air, or just easier fireplace use, our gas heating inserts deliver efficiency, comfort, and modern convenience.

Chimney Scientists provides expert installation of gas fireplace inserts throughout the Greater Philadelphia area, including Montgomery, Bucks, Chester, and Delaware counties, along with Carbon, Lehigh, and Monroe counties in the Pocono region.

What Are Gas Fireplace Inserts?

A gas fireplace insert is a self-contained, high-efficiency firebox designed to fit directly into your existing masonry or prefab fireplace. Unlike gas logs, which rely on the original fireplace structure, inserts are sealed systems that offer controlled heat output, reduced emissions, and stylish design options.

We install only sealed gas fireplace inserts and direct vent gas inserts, which safely vent combustion gases outside and pull in fresh air from the outdoors. This eliminates the need for a chimney damper while boosting efficiency.

Benefits of Energy-Efficient Gas Inserts

Today’s high-efficiency gas fireplace inserts are designed to meet the needs of modern homes. Homeowners love them because they offer:

• Lower heating bills: Heat the rooms you use most without overworking your central system.

• Cleaner combustion: You won’t need to worry about smoke, indoor air pollutants, or creosote anymore.

• Simple operation: Many models feature push-button starts or remote controls.

• No more firewood: Say goodbye to hauling logs and concerns about running out of fuel.

• Attractive finishes: Choose from classic or contemporary designs to match your décor.

If you’re looking for a low-maintenance fireplace upgrade, energy-efficient gas inserts offer unmatched performance and ease of use.

Direct Vent vs. Sealed Gas Fireplace Inserts

At Chimney Scientists, we install direct vent gas inserts—sealed combustion systems that use a co-linear venting setup. These systems draw air in from the outside for combustion and vent exhaust gases back out through the same chimney or wall penetration.

Benefits of sealed and direct vent technology include:

• 70–85% efficiency ratings

• Better indoor air quality than with a wood-burning fireplace

• Consistent, thermostat-controlled heat

• Safe operation with no open flames or backdrafts

This type of insert is ideal for homes with an existing chimney, and it’s the industry standard for gas fireplace conversions.

Gas Insert Installation Process

Our gas insert installation services include everything from venting and gas line setup to custom trim and surround finishes. Here’s what you can expect:

1. Home evaluation and venting compatibility check

2. Measurement and product selection with style and heat output recommendations for your living space

3. Chimney prep and gas line installation (if needed)

4. Fireplace gas insert installation with all necessary clearances and permits

5. Final inspection and system testing

We handle the entire process in-house to ensure a smooth, code-compliant install with no surprises. You’ll be enjoying your new fireplace in no time.

Converting Your Fireplace to Gas Inserts

If you’re tired of the mess and hassle of burning wood, our gas fireplace conversion service makes the transition easy. Whether you’re replacing a non-working system or just want a cleaner heat source, we can convert most traditional fireplaces into safe, efficient gas heating inserts.

We’ll evaluate your system and chimney to recommend either an insert or one of our gas fireplace logs, depending on your heating goals and budget.

Choosing the Right Gas Heating Insert for Your Home

We offer a curated selection of gas inserts for fireplaces from top manufacturers, available in a wide range of sizes, finishes, and BTU outputs. During your in-home consultation, we’ll help you choose the best fit for your vented gas fireplace insert based on:

• Room size and insulation

• Heating efficiency goals

• Style and aesthetic preference

• Existing chimney or venting system setup

Want a more rustic look? We also install wood stove inserts and offer full wood stove installation for homeowners who prefer a traditional feel.

Maintenance Tips for Gas Fireplace Inserts

Gas fireplace inserts require far less maintenance than wood-burning units, but routine upkeep is still important for performance and safety.

Here’s how to keep your insert in top shape:

• Have it inspected annually to check for debris, wear, and gas connection integrity

• Clean the glass and burners to maintain flame visibility and airflow

• Test your remote and thermostat at the start of the heating season

Our team offers professional service and troubleshooting for all installed natural gas or propane units.
