Choosing Between Gas Logs and Gas Inserts

Author: Sean Summers, NFI Master Hearth Certified Technician – WoodstovePro.com

If you have an existing masonry fireplace and want to upgrade its performance, two popular options rise to the top: gas logs and gas inserts. Both offer convenience, cleaner burning, and instant ambiance compared to wood fires — but they serve very different purposes. The right choice depends on how you use your fireplace, how much heat you want, and the overall look you’re going for.

Here’s a practical guide to help you decide between gas logs and gas inserts, along with the key differences every homeowner should know.

What Are Gas Logs?

Gas logs are decorative burners with ceramic logs designed to mimic a real wood fire. They install directly into your existing open fireplace and provide beautiful flame ambiance with minimal effort.

Pros of Gas Logs:

• Easiest and quickest installation
• Most natural-looking flames
• Great for ambiance and occasional use
• Lower upfront cost
• Works with natural gas or propane

Things to Consider:

• Provide limited heat compared to inserts
• Vent-free options heat more, but may not be allowed in all areas
• Less efficient than enclosed systems
  
  

Best for: Homeowners who want the look of a real fire without the work of burning wood.

What Are Gas Inserts?

Gas inserts are self-contained, sealed combustion units that slide into your existing fireplace opening. They use a direct-vent system to bring in outside air for combustion and exhaust safely outdoors.

Pros of Gas Inserts:

• Extremely efficient heating (often 70–85%+)
• Controlled, thermostat-ready heat
• Sealed glass front increases safety
• Reduces drafts from an old fireplace
• Modern styling and LED ember options
  
  

Things to Consider:

• Higher initial cost than gas logs
• Installation requires a venting kit
• Flames look slightly more controlled than open fireplaces
  
  

Best for: Homeowners who want a reliable, high-efficiency heat source — not just ambiance.
