Gas Fireplace Inserts vs. Wood Burning Inserts: A Comprehensive Comparison


Choosing between a gas fireplace insert and a wood burning insert can be a pivotal decision for homeowners seeking an efficient and cozy heating solution. In this article, we’ll delve into the technical details of these two insert types to provide clear and concise information for both technical and non-technical readers. Let’s compare gas fireplace inserts and wood burning inserts, considering essential factors like efficiency, installation, cost, and environmental impact.

  1. Fuel Type:

Gas Fireplace Inserts: These inserts are designed to burn either natural gas or propane. They offer the convenience of a consistent and controllable heat source.

Wood Burning Inserts: Wood burning inserts, on the other hand, use seasoned firewood as their fuel source. This traditional method provides the authentic crackling fire experience.

  1. Efficiency:

Gas Fireplace Inserts: These are known for their high efficiency. They often have an Annual Fuel Utilization Efficiency (AFUE) rating of over 80%, converting most of the gas into usable heat.

Wood Burning Inserts: Wood burning inserts’ efficiency depends on factors like the wood’s moisture content, the unit’s design, and operation. They can be less efficient than gas inserts due to heat loss through the chimney.

  1. Installation:

Gas Fireplace Inserts: Installing gas inserts typically requires professional expertise, including gas line connection and venting. It’s essential to comply with local building codes and safety regulations.

Wood Burning Inserts: Installation of wood burning inserts can be complex and may require chimney modifications. Proper venting and clearance around the unit are critical for safety.

  1. Cost:

Gas Fireplace Inserts: Gas inserts generally have a higher upfront cost due to the unit itself, installation, and gas line work. However, lower fuel costs can balance this over time.

Wood Burning Inserts: The initial cost of wood burning inserts may be lower, but consider the cost of firewood, storage, and potential chimney maintenance.

  1. Environmental Impact:

Gas Fireplace Inserts: They produce fewer emissions compared to wood-burning inserts, making them a more environmentally friendly option. They also eliminate the need for harvesting and burning firewood.

Wood Burning Inserts: While the use of sustainable firewood is an eco-friendly choice, inefficient wood burning can release harmful particulate matter and contribute to air pollution.

  1. Maintenance:

Gas Fireplace Inserts: These inserts require minimal maintenance, mainly involving regular checks for safety and performance. Cleaning and replacing components may be necessary, but less frequently compared to wood inserts.

Wood Burning Inserts: Wood burning inserts require more maintenance, including cleaning the chimney, removing ash, and ensuring proper air circulation. Regular inspections are essential to prevent creosote buildup.


In choosing between gas fireplace inserts and wood burning inserts, you should consider factors such as fuel type, efficiency, installation, cost, environmental impact, and maintenance. Gas inserts offer convenience, high efficiency, and low emissions, while wood burning inserts provide a traditional and rustic experience. Your choice ultimately depends on your heating needs, lifestyle, and environmental concerns. Be sure to consult with professionals to make an informed decision and enjoy a warm and cozy home with the right insert for you.
