What are ventless gas logs?

If you’re unsure what ventless gas logs are, they’re essentially logs that provide a mini fireplace—but without any pesky venting. These fireplaces heat your home in much the same way as traditional wood-burning fireplaces, and some models even offer features like logs that crackle.

Ventless logs are an efficient source of heat that allows heat and moisture to stay indoors because they don’t require a chimney to operate. They also recirculate the same indoor air without introducing fresh air into the room.

How do ventless gas logs work?

Ventless gas logs are made from refractory cement, allowing them to assume any shape easily. These logs are made to look exactly like natural wood logs. You won’t be able to tell them apart from the natural wood at a glance. Unlike traditional gas logs, ventless gas logs do not need a flue. They’re designed for use in fireplaces that don’t have an open chimney (like a zero-clearance fireplace) or where installing a traditional wood or gas log set is impossible due to space limitations. Ventless logs are inserted directly into your existing firebox and are installed using special hangers.

What type of fireplace uses ventless gas logs?

Ventless gas logs are used in fireplaces with gas burning and heat-producing features. These are ideally used in ventless fireplaces or where the chimney is sealed to avoid the heat produced from escaping outside the room. They are perfect for use in apartments and other joint living spaces because they don’t need a chimney or flue to operate.

What are the advantages of ventless gas logs? 

It’s essential to learn about the pros and cons of ventless gas logs to make an informed decision that works best for your home and your family. Here are some important advantages of using ventless gas logs:

Don’t require a chimney

Many homeowners prefer ventless gas logs for their ease of installation. As a ventless log set heats, it produces zero emissions, so it doesn’t require any venting to the outside. It gives ventless sets an advantage over traditional fireplace logs in terms of safety and cost savings because no chimney is required for installation. There are no vents to connect or draft openings to seal, making them a hassle-free option than conventional fireplaces.

Produce more heat

While ventless logs may produce more or less the same heat as vented logs, they heat the room better than the vented logs. Without a chimney or open flue, the heat stays indoors rather than being lost through your roof.


Ventless gas logs produce less pollution because they consume almost all of the fuel for combustion, resulting in less soot and emissions. Understandably, only a negligible amount of exhaust can justify them being ventless. Also, you are not cutting down trees to feed your fireplace, so ventless gas logs are a perfect choice for those conscious of their environmental impact.

Less fuel consumption

These ventless gas logs are 99 % efficient in converting the gas into heat. It means they don’t waste any fuel in the process and use less fuel to produce more heat than vented gas logs. If you are looking for ways to keep your gas bill low, then ventless logs are an ideal option. 

What are the drawbacks of ventless gas logs?

Like any other product, ventless gas logs also have a few drawbacks that can affect your final buying decision. Here are some of the important cons:

Flames don’t look as authentic

This disadvantage has more to do with your aesthetics. If you want your fireplace to look like a real wood fireplace, ventless gas logs can compromise that realistic touch. However, it might not be an issue for you if you are looking for more heat rather than the looks.

Not permitted everywhere

Depending on where you live, ventless gas logs may not be permitted. Some states and cities have banned ventless logs; others have specific regulations regarding their use or installation. It’s essential to check with your local government before installing ventless gas logs. You should also check to see if your home insurance company has any specific restrictions or requirements for gas logs in your area, as they may not cover damage caused by ventless gas logs.

Lack of flexibility

You can’t rearrange the logs as their design is fixed. These logs are designed so that flame doesn’t touch the logs to prevent carbon monoxide emission. So, if you want to rearrange logs in another way, you’re out of luck. However, the designs differ from brand to brand, so you may find sets with individual logs that can be arranged in any way you want.

Mold formation

Burning gas produces carbon dioxide and water vapors. In the absence of ventilation, ventless gas logs release moisture indoors, which can result in mold and mildew issues in the house if the ventless logs are regularly used for heating. 

Needs professional installation

You have to consider necessary specifications when installing ventless gas logs. Also, specific building codes need to be followed for safe installation. So, you will need to hire a professional to run proper safety tests before you can run your fireplace to avoid any future hazards.

Things to consider before buying ventless gas logs for your place

It would help to consider several factors before purchasing ventless gas logs to ensure they’re suitable for your home and lifestyle. Here are some of the most important factors to consider when buying ventless gas logs.

Fuel type

You have to choose between natural gas and liquid propane. Natural gas is the first option for many homeowners as natural gas line is present in most residential areas. But a propane tank is the only option for those who have opted not to install a natural gas line in their home, or it’s not reached their place for any reason. Propane tanks are easy to set up and take down. Once you’ve installed them, your log set should last approximately 2-4 weeks per tank of propane, depending on how frequently they’re being used. An important thing to consider here is that natural gas is cheaper than propane, but propane burns hotter than natural gas.

Log size

Most ventless gas logs are designed for a firebox similar in size to a traditional wood-burning fireplace, so don’t forget to measure your available space before purchasing. The size of the logs is crucial. Be sure to use logs that are compatible with your fireplace’s firebox. Using too large logs can cause damage and safety hazards while using too small ones will result in inefficient burning. Measure the front, back, height, and depth of the fireplace before purchasing gas logs. Also, follow the manufacturer’s instructions for recommended clearance.

Flame control options

One of many things to consider when looking for ventless gas logs is what kind of ignition system you prefer. You can buy gas logs with electronic ignition or a manual pilot system. In any case, you should opt for gas logs with multiple lighting options and safety features such as auto shut-off and thermocouple protection. Also, remember that most ventless gas logs need a more robust and dedicated heat source than fireplaces. Four flame control or ignition options are:

  • Non-piloted ignition system
  • Manual piloted ignition system
  • Manual pilot with remote
  • Electronic ignition system

Gas log style

These gas logs are highly efficient and made of refractory ceramic or ceramic fiber. Refractory ceramic logs are more durable and of better quality than fiber logs. You have several options in log style and designs. You can invest in premium brands for accessories such as crackling sounds and flame styles that look more realistic.

Frequently asked question

I have compiled some FAQs to answer your concerns regarding ventless gas logs. Go through these to help you make an informed decision.

Will ventless gas logs heat a room efficiently?

Ventless logs convert the fuel into heat with any substantial waste, so they are extremely good at heating where they are installed. Plus, ventless gas logs’ efficiency depends on how sealed your area is. The feeling of warmth comes not only from the burning fire but because of the trapped heat that is not vented outside. 

Do ventless logs cause breathing issues?

Burning ventless logs with closed doors and windows for extended periods can decrease oxygen levels which can cause breathing problems for sensitive people. Moreover, burning ventless gas logs produces a peculiar odor that can irritate vulnerable residents. And if you open the windows periodically to avoid this issue, the heating efficiency of ventless logs will be affected.

Are ventless gas logs safe to use?

It is an important point. One potential risk with ventless gas logs is carbon monoxide poisoning. But if you live in a well-ventilated home or have another source of heat, it shouldn’t be a concern. Using a carbon monoxide detector and oxygen depletion system (ODS) will give you peace of mind when using ventless gas logs. Still, if you live in a home with poor ventilation or are running an energy-efficient furnace, check with your gas company to see whether there are safety concerns before buying.

Can you use ventless gas logs in a vented fireplace?

You can effectively use ventless logs in a vented fireplace. However, ensure that the damper is closed as these logs don’t need venting. Keep in mind that even if the damper is closed in a fireplace having a chimney, some heat might escape, making the use of ventless logs in a vented fireplace somewhat inefficient.

Do all ventless gas logs smell?

Because they’re not connected to a flue, the odor of burning gas produced by the ventless gas logs stays inside. All ventless logs give a particular smell with varying intensity depending on their quality and brand. If you feel that the smell is stronger than it used to be or you don’t find it normal, it might be a sign that they could use some cleaning. The best way to deal with a clogged or dirty burner is to call a professional for help.

How do I stop my ventless gas logs from smelling?

You cannot stop the ventless gas logs from smelling, but many tips can help reduce the smell from burning ventless logs. Some tips that can help are:

  • Vacuum dust and pet hair from around the logs
  • Don’t use air fresheners in the room
  • Avoid using strong-smelling cleaning products in the area
  • Smoking inside can worsen the situation, so go outside to smoke
  • Use an air purifier for fresh and clean air

Final thought

After weighing all factors, ventless gas logs are an excellent option for many homeowners. They are less expensive than their vented counterparts, don’t require venting through a chimney or otherwise, and emit more heat than vented gas logs. If you live in an area that doesn’t ban ventless gas logs or if you want to save money while keeping your home extra warm, ventless gas logs are probably the right option for you.
