What is a Gas Fireplace Insert?
Giving up the idea of a wood-burning fireplace isn’t common to some people. But when you look up the numbers concerning efficiency, you will quickly fold and come to terms that a gas fireplace insert is likely the way to go. If you are still unsure, then you need to understand exactly how gas fireplace inserts work.
These appliances are fireplaces, typically made out of some sort of metal, that slide into the existing opening in the wall. They also have their own flue system along with exhaust. The infrastructure of the house is used in that case. The flue will usually go up the chimney and will lead out.
This is the moment where it is important to check out some gas fireplace consumer reports so that you can become familiar with a certain detail. The vent might be placed on top of the unit but it can also go through the back. This is pretty important because if you only have a chimney going up, you might not be able to lead the flue there.
On the other hand, if your fireplace opening is deep enough to accommodate both the unit and the flue, the pipe might actually be able to go behind the back of the fireplace and then all the way up the chimney. Some units come with the option to decide whether you want an on-top or a rear-end venting but they might be hard to come by.
In any way, the flue system will be a lot smaller. All the direct vent gas fireplace reviews will show you that these systems are way more efficient than classic fireplaces. You don’t have a huge gulf of smoke going up the chimney. So the flue goes up the existing chimney and is then sealed and capped off at the top of the roof. That’s where the damper is located. Check out our reviews on the best air purifiers for smoke.
Running gas to the fireplace is a must but electricity should be run as well. This is needed because the most efficient direct vent gas fireplaces might also have fans.
The best part is that the mechanism allows your unit to preserve all the hot air and sort of bringing it to you. The fireplace will “control” the air by bringing in just as much oxygen needed for combustion. The unit is completely sealed and there’s also usually a glass panel on the front. This will prevent cold air from coming in when the fireplace is not in use. There are typically 3 sizes:
- Small
- Medium
- Large
Depending on the size of the room, getting a certain type of fireplace is in order. Measuring is also important so that all the gas and electric connections can be figured out. In general, you are looking at about 78% to 85% efficiency when you get one of the nicest gas fireplace inserts brands. Having a remote control is a luxury but it will really make a difference when it comes to the price.

Best Gas Fireplace Inserts (New List)
1. Peterson Real Fyre Live Oak Log Set
This is a 100% natural gas unit and it should be used as such. Your fireplace needs to be properly vented. The Peterson Real Fyre Log Set comes with a metal frame and that’s also the tube for the gas. The logs are painted professionally by hand and you will also notice dark shades on them in order to enhance realism. The material of the logs is ceramic meaning they will be able to last a very long time.
Additionally, the 6-log set will give you residual heat after you turn the burner off. At maximum power, the unit will produce about 75 000 BTU. Installation is not hard as you can simply insert this 24-inch unit inside your existing fireplace. The gas connection can be tricky so you should get a professional to do it. The best part is that connecting the burner is optional but why would you need just the logs?
2. Empire Tahoe Deluxe Millivolt Fireplace
This next fireplace insert is a top quality model. It is a completely closed system with only one flue vent hole on top. The unit will not give you huge trouble when you connect it as long as the flue and the chimney are on top. You can also have a rear-end venting although it might not be worth the hassle. The fireplace insert works on propane and will give you 20 000 BTU at maximum.
The size of the unit is also impressive and you will need a fireplace that has at least 16.5 inches of depth. The opening of the firebox has to stand at 37 x 35.5 inches. No remote control is included but this is rather usual for such propane fireplace inserts. There is also a fan to assist in blowing the heat around but this purchase can easily be made separately.
3. Duluth Forge Ventless Dual Fuel Gas Log Set
Duluth Forge raises the bar with this dual-fuel, functional, and good-looking product. The Log Set has a built-in electronic ignition. Once lit, you can use the remote control to turn the unit off/on and set the thermostat temperature.
The logs are designed to be stacked in a specific way, which is the key to a good appearance. A combination of lava rocks and embers neatly placed together and not just freely thrown in the fireplace makes any room look welcoming and cozy.
The size of the logs is 18 inches. You need 20 inches in height, 29 inches in front, and 22 inches at the rear to allow air movement. If the fireplace is too small, the logs will not stay lit because the Oxygen Depletion Sensor will be activated to shut the unit down.
You receive the unit set for propane, but it can easily be set for gas. It doesn’t require electricity but uses AA batteries. Using a blower and installing it in an outdoor fireplace is not advisable.
4. Napoleon Grandville VF Series Vent Free Natural Gas Fireplace
There is a very good chance that this is the best value for money natural gas fireplace insert that you will encounter. It is a pricey product but definitely brings you everything you want from a cozy fireplace without extra hassle. The Napoleon Grandville Natural Gas Fireplace comes with a millivolt remote control, has a fireplace screen, a hood, and even adjustable heat control.
Among other options, you can select to have a fan but it is purchased separately. It is also a completely vent free installation which requires no exhaust vent. Oxygen depletion is a problem in that case, but the unit is equipped with its own safety detector. The fireplace will automatically shut off in case oxygen levels drop too much. In the actual firebox, you will find a steel frame and Phazer logs. The area you can hope to cover with this unit is about 1200 square feet.
5. Majestic Quartz QUARTZ32IN Direct Vent Natural Gas Burning Fireplace
The Majestic Quartz Fireplace shows a refined and straightforward design alongside flexibility. Provisioned for installing on floor level, yet it can also be elevated on a hearth.
You can use it without a blower. Hence there will be no need for electric power because there is a battery backup in the control system. Or, if you don’t mind using electric power, you can add a blower to even out the heat spread. Venting is possible through a side wall, the rear of the unit, or through the roof, depending on your chosen place of installation’s specific characteristics.
As if all the options so far are not enough. You also have the possibility to convert the interior and choose between traditional and contemporary. The remote control is also optional. You can choose from one of the provided by Majestic models or even get an aftermarket compatible one.
With 21000 BTUs maximum heat output and 36 x 16.31 x 34.06 inches in size, this natural gas burning fireplace will warm up a wide area at low cost and without sacrificing living space.
The tempered front glass and realistic-looking logs add to creating a cozy atmosphere.
Comparison of a Gas Fireplace Insert to a Classic Fireplace
So you already have a fireplace at home. Why would you spend a 4-digit sum on an appliance which gets built-in the hole that you already have? Well, since we all have our particular needs it is better to find out for ourselves what exactly fireplaces vs fireplace inserts mean. There’s no point in providing any more context as to why a gas stove insert for a fireplace is the way to go. Here are the main focal points of our comparison:
No Tending
Keeping the fire going steadily when using wood is something that requires some experience. With gas stove inserts even a child can control the intensity of the flames. The gas will flow steadily and regularly all the time until the tank is empty. The level of oxygen, cold drafts, and other similar things will not affect your fire. Also, logs will not burn away thus requiring even more attention.
No Hard Fuel
Speaking of logs, that’s something you don’t have to care about at all. You won’t have to cut, chop, and sort and pieces of wood when you opt for a gas fireplace insert. Hauling, arranging, and seasoning the logs is also a very unpleasant activity. Keep in mind that logs need to be very dry and this typically requires them to stay somewhere for at least 6 months. All you will have to do is replace one propane tank with another.
Easy Setup
No need to pile up pieces of paper, think about the timber, or any other necessities which come into play when you start an old-fashioned fire. In our case, everything happens at the push of a button. Gas fireplace inserts usually have a Piezo ignition which means you are starting the fire without any hassle.
Clean
This might be one of the biggest blessings of gas fireplace inserts. With the exception of the annual inspection of the system, you have no other cleaning duties. Not only fireplaces but even the finest wood-burning stoves will give you plenty to clean. You will have obligations related to taking the tray out after every use. Additionally, you will need to think about soot in the chimney. Fireplaces require an impeccable flue and piping system so you need to clean messy areas often.
Specific Temperature
When looking to maintain a certain value on the thermometer you simply need to adjust the thermostat. When you use real gas logs, you need to manually control the burning. It is also known that raging hot fires are not very efficient. Unfortunately, people often have little control over the strength of the fire when using logs.
Efficiency
Because the chimney is pretty wide and completely open, cold air will constantly make its way in when the fireplace isn’t working. On the other hand, this very chimney will also allow much of the “good” heat to escape through it. Gas fire inserts for existing fireplaces will trap the hot air in the room and will not be able to escape through the narrow flue system. Ventless inserts are even more productive giving you more than 70% efficiency. The good old fireplace which makes you feel cozy and makes reading a book in front of it a delight will provide you with only 15%-18% of efficiency.
Placement
Yes, an opening is required but you can still have a gas fireplace insert with a blower in any room you wish. This includes the bathroom as well. Since there is no smoke, no fumes, and no pollution, you can have this appliance in the most delicate premises. Even a basement is an option.
Fireguard or Glass Doors
You will need to buy a fireplace cast iron screen separately when using a classic fireplace. In the instance where you get a gas insert, there will for sure be some sort of a built-in screen. It typically comes in the form of sealed glass doors. They aren’t only stylish but are exceptionally useful and functional. The doors will never get too hot to touch. This way children and pets will not be in danger of being burned. The doors will also prevent hot air from escaping the room and will stop any cool draft from entering through the venting system. We already cleared that up above.
Comparison of Gas Fireplace Inserts to Electric Fireplaces
In all fairness, the most distinguished electric fireplaces on the market today have a ton of advantages. What do they have?
Space-saving
They aren’t bulky and you have 3 main ways of installing them. An electric fireplace can be freestanding, wall-mounted, and recessed.
Safety
You got no hoses and no combustible fuel here. Electric fireplaces are basically space heaters.
Perks
an electric fireplace typically comes with a LED display, remote control, timer function, and many other cool features.
Decorative Animation
You can have your flames in a number of available colors. Many units also allow you to control the visual intensity of the flames
But we can’t dismiss all the great qualities of a gas fireplace insert, can we? With them, we get outstanding efficiency as the warmth is really abundant. No electric heating appliance can beat one that uses propane or liquid gas when it comes to BTU. Furthermore, electricity will end up costing more in the long term.
The room will also get heated quickly when using something on fuel. Most of the available electric heating and cooling devices will require some more time in order for their effect to be felt. Convection heaters, as well as forced-air heaters, cannot give you robust and instant heat. This is definitely a great trait of all gas stoves.
Drawing the Line Between Vented and Vent-free Gas Logs
We simply need to address the most important difference between gas logs because they are an essential part of our guide. You already know that these products are a popular solution which substitutes a full-sized gas fireplace insert. In this case, you insert only a set of logs.
So how do we tell the vented from the vent-free log set? Let’s begin by talking about the 1st group and then we will draw out conclusions.
Vented Logs
There is one almost a 100% sure sign that you are looking at a vented gas log set even without knowing the actual connections and constructions. Look at the flames. If they look exceptionally realistic meaning that they wiggle around the logs and dance between them and burn through them, then this is a vented set.
This means that the unit requires a constantly opened damper and a very good flue system. There is barely any difference between this product and a usually vented gas fireplace insert. You will still require an exhaust pipe as well as an intake one.
A downside here is that these log sets rarely come with any type of glass doors. You will need a pair of these, however, if you want to prevent any cool air from invading your premises. You also want to stop the hot one from escaping through the flue.
These beautiful logs will give you exceptional flames – big blue ones, orange ones, you name it. The main reason to purchase one of these sets is aesthetics. Even though they are gas-fueled, they will not give you very much efficiency. They produce radiant heat meaning that you will feel warmth only if you sit tightly in front of them, reading a book or sipping on something delicious.
Vent-Free Logs
Next, we look into vent-free logs and see if unvented gas log fireplaces right for your home. These products people get in order to heat a room entirely. They do not depend on power outages and will give you efficiency ratings through the roof. So let’s start by looking at the flames again. Here the gas-fueled fire cannot interact with the artificial logs. This leads to the fire looking a little bit unnatural and not especially realistic.
Vent-free sets usually launch the flames through posts also known as cutouts. They are right between the logs. You will encounter 2-post sets and 3-post sets. The former might give you just a bit more realism. These products will usually include a variable remote which will let you adjust the height of the flames. This will also play a role in how much heat you get in the room – larger flames, hotter room. Isn’t that nice little trick about how to get more heat from a gas fireplace?
Now let’s talk about the effectiveness and functionality of vent-free logs. They are significantly easier to install as there is no vent system. All the heat will remain in the room meaning that the unit will give you something close to 90% efficiency. There are two important points here, though.
First of all, this type of heating runs the risk of oxygen depletion. If the unit doesn’t come with a detector, you should definitely get one. What’s good is that those ventless gas logs usually have a pilot light. In case it goes out, the whole unit will automatically shut down. This type of safety system has been used for more than 50 years and with great success.
Next, since we aren’t talking about the radiant heat here, all the warm air will automatically ascend towards the ceiling. The way the heating process here works is very similar to convection units. It is best if you combine your vent-free log set with a top-quality wood stove fan. See our wood stove fan reviews to find the perfect match. It will distribute the heat evenly around the room and will prevent the warm air from evaporating through the ceiling. In fact, an overhead ceiling fan is also an option here.
In short, here’s what we get from each model:
Vented
- Beautiful, realistic flames
- Require a vent system
- Should have doors
- Radiant heat – can be felt in front
- Hard to warm a whole room
Vent-Free
- Logs do not “burn” – unrealistic flames
- No need for a chimney or any vent system
- Will heat up a whole room easily
- More dangerous – may deplete oxygen in the room
- Work better with a fan
Installing Your Vented Gas Fireplace
We aren’t going to waste any more time talking about direct vent gas fireplace ratings or how they work. So we will cut to the chase. You need to have two lines inside your fireplace prior to putting the insert in there – a gas one and an electric one.
Running the vent lines is the next step and this means that you will have to venture to the rooftop. Once you are in the chimney, see how many flues you have. If there’s an uncovered one, then this is for the heating boiler. The one with the damper is for your fireplace. Well, now you will need to get rid of the damper for safety reasons.
Take the exhaust liner along with the intake liner down through the chimney and inside the fireplace. While still on the roof, use some high-temperature silicone and seal the pipes onto the chimney with a metal top plate. Now use a termination fitting in order to merge the ends of the pipes on the roof.
Running the gas line should be done by a certified professional. This job needs to be done impeccably and according to all standards. It requires the use of t-fittings, shut-off valves, and other specialized supplies in order to make the whole project not only functional but also safe.
In the actual fireplace, pros usually use flexible connections. You don’t want to impair the gas insert as you drive it in. Don’t forget to plug the unit into the electric socket before actually inserting it into the fireplace. The final connection is the gas connection. Before you turn on the gas, make sure the intake and the exhaust connections are also properly made. It is best if this is done again by using the high-temperature silicone.
Finally, attach the glass doors and you should be ready to go!
