These days, more and more people are converting their wood-burning fireplaces into propane ones. And it is easy to do, with an insert that just slots into your current mantle. But what are the benefits of making the switch? Let’s take a look now! 


Propane fireplaces or freestanding sources come in many styles and colors, so you are sure to find one that matches your existing decor. Plus, they are a heat source that works even when the power is out!

You don’t need to worry about keeping warm in a blackout now, just make sure you have your propane fireplace and some propane to use! 


Propane fireplaces are extremely convenient to use too. You can enjoy the heat and the glow of a fire whenever you want, without needing to set the fire yourself!

Plus, modern propane fireplaces come with remotes and thermostats that allow you to control the heat from your couch! You can’t get a more convenient fire!


Propane fireplaces offer 89% efficiency, making them four to five times more efficient than a wood fireplace. Propane fireplaces are more efficient as all of the heat is staying in the room.

When you use a wood-burning fireplace, most of the heat goes up the chimney with the smoke, meaning you need to burn the fire for longer to feel the benefits. 

You don’t need to do this with a propane fireplace, you can enjoy more of the heat! 

They Are Healthier 

While wood smoke smells divine, it isn’t great for your body. The fine particles, known as fine particulate matter, are a health threat from wood fires, causing respiratory problems and other issues.

Propane fireplaces don’t come with these issues, making them the better choice. 

Better For The Environment

Propane fireplaces are not only more efficient but are better for the environment too. By comparison, a wood-burning fireplace emits up to 4,000% more emissions than a propane one!

  3. If gas comes out of the pilot but it doesn’t light, clear any gunk in the igniter and thermocouple with a can of compressed air 

If after this, there is still no fire, it’s time to call in the professionals!
