How To Choose The Best Gas Fireplace

To come up with the above gas fireplace insert rankings, we tested the products based on various factors including pricing, heating capabilities, type of fuel used (natural gas, liquid propane or both), ease of installation, ease of operation, vented or vent-free, and additional features.

But that’s not all…

We also listen to input from real-life users of the products and experts in the industry.

When determining the best gas fireplace insert, it mostly boils down to your individual needs. While your main issue may be budget, someone else’s may be the quantity of heat produced, aesthetics, or the comfort of operating the equipment.


Establish exactly what you want first and then when you see the equipment with the features you think suit you best, it will be a case of love at first sight.

Buyer’s Guide

If this is the first time you’re considering to buy a gas fireplace, there are a few important things you need to keep in mind to ensure you end up with quality equipment that suits all your individual needs. For example, the size of the fireplace, how high your ceilings are, the climate of the environment you live in, etc.

What To Consider Before Buying Your Gas Fireplace Insert

First, there are direct vent and vent free gas fireplaces. It’s important to check with your local government whether direct vent fireplaces are allowed in your town/state before buying one.


You may find yourself in some legal trouble.

No one wants that.

But, in some U.S. states, vent-free fireplaces are banned due to the accumulation of moisture in homes with tight seals.

Direct vent gas fireplaces provide more venting options—typically, on the top and on the rear of the unit. This provides more options for installation. They also use air from outside for combustion. The exhaust air is directed outside the house, reducing the competition for oxygen.

On the other hand…

Vent free fireplaces are cheaper to maintain due to lower consumption rates. They’re also easy to install in rental homes or after doing renovations and make for a reliable source of heating due to the 99% efficiency.

The biggest question is…

The type of fuel you’re going to use. Namely natural gas or propane. If you’re in a residential area where there’s already a natural gas line, then this is a no-brainer. However, if you’re planning to make a portable or outdoor fireplace, setting up a propane tank anywhere within the compound will do the trick. Both are clean and cheap sources of energy and the best fireplace inserts can run on both.


Some gas fireplaces come installed with battery backup systems that allow continued use even during power outages.

Additional expert tips

Lastly, you need to consider the cost of the fireplace as well as installation fees. Unless you really trust your hands with tools, it’s best to leave the installation of hearth products to a professional. They’ll do a quality job and also take care of the necessary inspections and approvals.

Now that we have some background information, let’s look at some of the best gas fireplace inserts you can buy in 2017.

A Complete Analysis Of Our Top 6 Gas Fireplace Inserts Selections

#1 Duluth Forge Dual Fuel Vent Free Fireplace Insert

Appearance and Hardware

The Duluth Forge Vent Free inserts measures approximately 14 x 24 x 29 inches. It weighs only 47.6 pounds. It’s fitted with a removable metal mesh screen door and a realistic firebrick painted interior with fairly realistic logs. It also comes with a thermostat remote control and a burner.


The blower kit is sold separately.

Features and Performance

The Duluth Forge Vent Free insert comes with zero clearance which enables the owner to build a custom fireplace for their home. Choose to pair it with a face mantel or recess it directly onto a wall and you will be good to enjoy some warm times.

The fireplace insert is fitted with lots of features such as:

  • An oxygen depletion sensor with automatic shut off for safety
  • Battery assisted piezo ignition for quick lighting
  • Burns propane or natural gas to radiate 26,000 BTU of heat capable of heating 1,350 square feet of space.

The Duluth Forge is fairly easy to install, even for one person.

It does its job pretty well.

The flame is easily adjustable to make it more suited to a large or small room. The logs can also be easily glued back in case they are broken during shipment or at home.

The remote control system also works perfectly, and since it uses batteries and the insert runs on gas or liquid propane, you can still keep your loved ones warm even in case of an electricity outage. In case the batteries run out, then it is time to go manual.

Be careful with the logs!

Otherwise, they may fall apart and give you a hard time trying to put them back together. Also, using the remote control may be a little confusing so take your sweet time.

  •  Installed with proprietary dual fuel technology that can use both liquid propane and natural gas
  •  Thermostat remote control technology available for easy control
  • Oxygen depletion sensor (ODS) that shuts off automatically when it drops below safe levels for safety concerns
  • Economic performance with 99.9% efficiency, hence no outside duct or chimney needed
  • Efficient heat level control

  • Does not operate at elevations higher than 4,500 feet altitude.
  • Complicated remote control that may take a while to get used to

  • Electronic spark ignition system for easy lighting with a safety switch in case of overheating

The external thermostat fan runs on electricity. This is in addition to the gas that heats the air. However, the thermostat fan does work perfectly.

In fact…

Some of the gas fireplace inserts we looked at cost upwards of $4,000. The Sure Heat Vented Fireplace does a pretty good job warming a small room.

Some of the features we really liked about the Sure Heat Gas Log set are:

  • High-performance glowing embers radiate twice as bright as standard embers
  • It has eight hand-painted refractory cement logs that are incredibly detailed. Plus, they’re traditionally arranged on a tiered grate, creating a realistic look of a mature wood burning fire
  • Simple to operate and maintain without producing ash—another benefit of gas inserts over using real wood!
  • It has manually controlled valve system designed to work in a vented environment and comes ready to connect to your standard natural gas fuel supply
  • The U-shaped dual burner is pretty innovative. The flame pattern it produces makes it look like the flames are dancing.
  • The small and compact design can fit pretty much anywhere in your home

However, there are couple things you should know.

about this gas fireplace insert. First, the logs may emit some fumes the first few times they’re used. But these go away after the fourth or fifth use. You may also notice a whistle from the regulator on the flame bar when the gas is turned past a certain threshold. This goes away if you adjust the gas either up or down.

After buying the Sure Heat Vented Fireplace, it would be a good idea to buy a separate flexible hose pipe and ball valve. These will cost you between $20-30, but it’s money well spent considering the solid gas line that comes with the kit is easily kinked.


a lot of users have raised this issue.

  • Very affordable at only $141.04
  • Fits in all fireplaces measuring at least 28 x 15 x 21 inches

  • Lacks remote control capabilities
  • It is a vented unit lit using a match hence has no on/off switch
  • Only 12% efficient thus requires an open and working flue
  • Low heat output which may need you to look for alternatives during winter

Does vent free do the job, or will I still smell the gas and by-products in the house?

No. Quality vent free gas fireplaces are more than 99% efficient, meaning any by-products will be negligible to cause any atmospheric changes in the room.

Where is the best spot to install?

Depending on your gas fireplace, the best place would be in an existing brick fireplace, in a corner, or recessed on a wall where the gas supply line passes through. For outdoor use, propane fireplace inserts are the most recommended.

Do I need a vent pipe?

For vented fireplaces, yes. For a vent free fireplace, you will not need one.

Will I be able to use the fireplace even if electricity runs out?

Yes. Gas fireplaces do not need electricity to run. Electricity is only used for external fans or automatic ignition systems.


Having a quality gas fireplace in your home will definitely make your place warmer and cozier, without all the smoke, wood, and ash associated with traditional fireplaces. When it comes to the specifics, however, it all boils down to your needs and preferences. Consider how much space you have for installation, the budget you’re operating on, features of the various fireplaces, and any other factors that you may deem important to you.
