Buyer’s Guide

This guide covers some of the things you need to consider to ensure that you get the best fireplace insert. Going through fireplace insert reviews is great, but having the knowledge you need to make your selection is equally important.

1. Fuel Preference

As you’ve seen, there are different types of fireplace inserts. The major difference between them is the fuel source they use.

You should consider getting an electric fireplace if you’re looking for a pocket-friendly solution. These fireplaces are also decorative, making them an excellent option for people who value aesthetics. You won’t have to worry about emissions or open flames as well.

Gas fireplace inserts are a great choice for people who are after affordability but prefer real flames. You’ll have an easy time setting them up if you already use gas at your home. They are convenient since they light up at the push of a button, and you won’t have to deal with ashes or strenuous processes to refill them.

Wood burning fireplace inserts make excellent replacements for traditional wood fireplaces. They have fewer emissions, burn cleaner, run longer, and use less firewood. You should consider getting one if you want to retain the same fuel source you were using for your masonry fireplace but want to upgrade to something more eco-friendly and efficient.

2. Heating Capacity

Before making your selection, you should check out the fireplace insert’s heat output to see if it can handle the size of your room. That way, you’ll be able to tell whether it’s going to meet your heating needs. For instance, if your room is 1800 square feet, you should get an insert with the capacity to heat the room sufficiently.

Going for a fireplace insert with a higher output might work against you since the room might get too hot and uncomfortable. A fireplace insert with a lower heat output might not meet your needs at all. Remember to get the dimensions of your room before you start shopping to get the right fireplace insert.

3. Efficiency

As we mentioned earlier, one of the benefits of using fireplace inserts is that they are more efficient. However, you should keep in mind that some units are more efficient than others. You want to go for models with high efficiency ratings so that you keep your energy costs as low as possible.

4. Features

If possible, purchase a fireplace insert that’s customizable or has adjustable settings. That way, you’ll be able to personalize and enhance your experience. You should also do your due diligence and ensure that the unit you want has some safety features.


1. Are fireplace inserts safe?

Yes, they are. Manufacturers ensure that they have several in-built safety features. For example, some electric fireplace inserts switch themselves off in case they overheat.

Modern gas and wood-burning fireplace inserts also produce the least amount of harmful byproducts compared to their predecessors. As you can see, you won’t have much to worry about as long as you use the fireplace inserts appropriately.

2. What type of fireplace insert should I get?

Electric fireplace inserts are the most affordable in all aspects. Reason being, they don’t require gas or wood refills. They also don’t need thorough cleaning routines or regular maintenance checks. Since there’s no real fire, you won’t worry about fire hazards or the glass becoming dangerously hot.

Gas fireplace inserts are second when it comes to efficiency and safety. They cost a bit more than electric fireplaces since you must cover the cost of propane or natural gas. Regular checkups are also mandatory to help avoid gas leaks and other safety hazards. However, you will get to enjoy the ambiance of a real flame.

Lastly, we have wood-burning fireplace inserts. They have the lowest efficiency when compared to the other two, but they are significantly better than masonry fireplaces. In addition to high running and maintenance costs, they may also emit harmful byproducts into the air.

Consider your needs, budget, and preferences before you settle for a fireplace insert.

3. Do all inserts require a vent?

Some do while some don’t. Electric units don’t require one, while wood-burning fireplace inserts require a vent or an existing chimney. Gas fireplace inserts can be either ventless or vented.

Vented gas fireplace inserts take the byproducts outside through the vent, while vent-free units ensure that most of the byproducts burn – resulting in increased heat output. The downside to using ventless gas fireplace inserts is that the remaining byproducts might still find their way into the room.

Make sure you confirm whether the fireplace insert you choose requires a vent before you buy it.

4. How should I clean my fireplace insert?

To clean an electric fireplace insert:

  • Simply unplug
  • Dust it off
  • Then wipe with a damp piece of cloth

Gas and wood-burning fireplace inserts require a more detailed approach. Since the flames are real, there’s the possibility of soot formation. You should, therefore:

  • Disassemble the parts carefully
  • Clean each part using a damp cloth dipped into some warm soapy water
  • For tough stains, continuously dip the cloth in the water and wipe it again as needed
  • Once you’re satisfied, rinse the cloth with clean water
  • Rinse each part with the cloth
  • Leave them to dry and re-assemble

Most fireplace inserts come with manuals that have specific instructions on how to clean and maintain them. All you’ll need to do is follow the instructions, and you’ll be good to go.

5. Can I switch the location of my fireplace insert?

Yes, you can. If you’re moving to a different house or you’ve got another location for the insert, all you’ll have to do is disassemble it. However, we advise gas and wood burning fireplace owners to contact a professional for re-installation – for safety purposes.

6. How do I pick the right fireplace insert size?

The first thing you’ll need to do is to measure the dimensions of your existing fireplace.

Once you have the measurements, go for a fireplace insert with smaller dimensions. It should be smaller by an inch or two. That allowance simplifies the installation process and leaves room for hosting a fan.

7. Can I burn wood and other materials in my fireplace insert?

If you’re using a wood fireplace insert, you can opt for eco-friendlier alternatives. Some of them include; recycled coffee grounds, wood pellets, and wood bricks. Other than the recommended options, you should never burn any other material in your wood-burning fireplace insert.

Never attempt to burn any other material apart from natural gas or propane in gas fireplace inserts. It’s impossible to burn anything in electric fireplaces due to the absence of real flames.

However, you should still avoid inserting or lighting anything. The electric insert will get destroyed if you do since it can’t withstand real flames.


Now that you’ve come to the end of this review, we trust that you’re fully equipped with the knowledge you need to purchase the right fireplace for your home. We made our selection based on quality, aesthetics, and efficiency to ensure that everyone gets the right fit.
