gas logs

If as a new homeowner, like me, you’ve got yourself a gas fireplace but you might still be wondering what kind of logs you should get, right? There are several options, such as some refreshing pine, or beautiful red oak.

That being so, you might be searching for something with more value for its worth and would last longer. Something like gas logs. The question of ‘how long do they last’ might be on your mind.

There’s no straightforward answer to this question since it depends on a few factors. Depending on their components, material they are made of, as well as your usage – they can last from 3-10 years.

The answer could be the main determinant of whether you’ll purchase them or not. Stick around to get a better understanding of their lifespan, types, installation, as well as maintenance.

What Are They?

They are artificial logs designed to be used in gas fireplaces or gas log sets.They are typically used in place of traditional wood logs in a fireplace. They are designed to work with gas burners that provide the flame and heat. When the gas valve is ignited, a yellow flame interacts with them, creating a visually appealing and realistic fire effect. 

These ceramic logs might look like any firewood log you’ve seen before, but they are not. They’re specifically made from extracted bisque ceramic clay. Some manufacturers also use molded ceramic fibers as well as cement.

These provide a cleaner fire-producing option, as opposed to conventional firewood. Also don’t give off as much soot and last much longer. Their fire is fed with natural gas and propane, which is more eco-friendly than burning wood.

How Long Can Gas Logs Last

The reality is that there’s no straightforward answer to this question since it depends on a few factors. Its wear can be influenced by the type used, its components, as well as your usage.

Let’s first explore the types of gas logs available and how long they may last.

Types of Gas Logs Sets

There are two main types in the market: Vented and ventless gas. Each has its advantages and disadvantages with regards to how long they will last.


The vented option is made for those who would value the aesthetic appeal over its heat efficiency.

Since vented gas logs emit carbon monoxide, they require ventilation, ergo ‘vented.’ This is why these types don’t provide much heat, since it easily escapes from the vents.

These logs typically last up to 10 years, which is one of the longest-lasting fire logs out there. This is also subject to how much you use the logs.

Vented gas logs need a chimney to be operated to disperse the heat and smoke. This means that the installation process would be much easier. All you have to do is just replace your firewood logs with those.

That being said, vented logs might require more fuel and energy than its counterpart.


The vent-less logs, unlike the vented ones, are more useful when it comes to heat distribution. While they do offer more warmth, they aren’t as design-oriented as the vented ones.

Since these logs don’t require any ventilation from a chimney, they ignite smaller fires. Vent-less are perfect for heating your room. All you need is a firebox and a gas line to diffuse its emissions.

Although vent-less don’t require as much energy as vented, they won’t usually last as long. They’re expected to last up to 3-5 years. But, as aforementioned, it also depends on your usage. If you’re in the winter season, you’ll probably burn through them faster.

Ventless gas logs are also more prone to combustion, which means that you might notice a distinct odor when using them.

To that end, each type offers its unique benefits. Whether you value appearance over coziness or vice versa, you’ll be sure to find your fit.

Components Of The Gas Logs

They can be made out of three different components. Let’s get a deeper look into each material and its longevity.

Refractory Cement

These are essentially made of cement. While they do provide more realistic-looking logs, they don’t last as long as other types.

Since they’re made of cement, they’re not as heat-protected as other materials. This is why refractory cement ones can last up to 2-3 years.

Ceramic Fiber

The ceramic logs provide more benefit and quality than the cement option. It provides the indistinguishable appearance of firewood as well as longevity.

They can last up to 10 years or more. These are also considerably more budget-friendly.

Refractory Ceramic

The refractory ceramic option offers logs with a mixture of both cement and ceramic. They’re more versatile in their placement in vented or ventless fireplaces . They are also very durable as they can last up to 3-5 years.

Why To Use Gas Logs

They’re more cost-effective than firewood logs. When you count the time it takes to chop your firewood and clear the chimney of any soot, you’d want to opt for the breezy maintenance that these provide.

They are less prone to fire hazards. They produce a low flame and wouldn’t kindle dangerous flying sparks like firewood logs.

They’re customizable. If you prefer your logs to look a certain type of way, these would be the best viable option.

As you explore options for a new log set, you will come across a range of simulated wood types available, including red oak, golden oak, juniper, and more. 

Here’s a table summarizing the size commonly available:

SizeLength Range (inches)Suitable For
Small12 – 18Compact fireplaces, decorative purposes
Medium18 – 24Average-sized fireplaces
Large24 – 36Larger fireplaces
Extra-LargeExceeds 36Oversized fireplaces, custom-built setups

Remember, these size ranges are approximate, and specific options may vary between manufacturers. 

How Much do They Typically Cost?

The cost of a gas log set can vary widely depending on several factors, including the brand, size, material, design, and additional features like remote control or variable flame. 

Generally, they can range in price from around $200 to over $1,000 or more.

Gas Log SetPrice Range
Entry-Level$200 – $500
Mid-Range$500 – $1,000
High-End$1,000 and above

Do Gas Logs Use a lot of Gas?

They are generally designed to be efficient and use less gas compared to other heating options like traditional wood-burning fireplaces. 

However, the consumption can still vary depending on several factors:

BTU Rating:

They have a British Thermal Unit (BTU) rating that indicates their heating capacity. Higher BTU-rated logs can consume more gas to produce a higher heat output. If you prefer a more substantial and warmer flame, it may result in slightly higher gas consumption.

Flame Height:

The flame height can be adjusted, allowing you to control the heat output. By reducing the flame height, you can decrease gas consumption and conserve energy.

Duration of Use:

The longer you keep them on, the more they will consume. It’s more energy-efficient to use them when you need them and turn them off when not in use.

Efficiency of the Fireplace: 

The efficiency of the gas fireplace itself can impact gas consumption. Well-designed and properly installed fireplaces can maximize heat output and minimize heat loss, resulting in more efficient gas usage.

Insulation and Room Size: 

The insulation of your home and the size of the room can also affect gas consumption. A well-insulated room will retain heat better, allowing you to use the gas logs more efficiently. Larger rooms may require more gas to achieve the desired heating effect.

Overall, they are considered a relatively efficient heating option compared to other alternatives. 

What Kind of Gas Do Logs Use?

They typically use either natural gas or liquid propane as the fuel source. The specific type of gas used by the logs depends on the configuration and setup of your fireplace.

If your home is connected to it, natural gas is a clean-burning fuel that is delivered through underground pipelines, eliminating the need for storage tanks. The logs designed for natural gas will have specific components and connections suitable for this type of fuel.

How to Maintain Gas Logs

Gas log sets generally do not require daily maintenance, but it is important to have them inspected by a professional on an annual basis. During this inspection, the logs should be carefully examined for any cracks or breaks, and if they are found to be in poor condition, they should be replaced. 

Additionally, the valves, pipes, and gas connections associated with them should be inspected to ensure they are in proper working order. 

For vent-free log sets, it is recommended to clean the ember bed and logs regularly to remove any any soot and debris buildup. 

If you have vented gas logs, it is crucial to have your chimney inspected and swept once a year to maintain proper ventilation and safety. Here are a few easy steps to follow to make sure your gas logs are in tip-top shape.

Is it OK to Leave Gas Logs On All Night?

Leaving gas logs on overnight can be potentially dangerous and is generally not recommended. It’s essential to prioritize safety when using any gas appliances, including gas logs. Here are a few reasons why leaving gas logs on all night is not advisable:

Fire hazards

While gas logs are designed to be safe and efficient, any appliance that involves an open flame poses a fire risk. A malfunction, gas leak, or other unforeseen issues could lead to a fire hazard if left unattended for an extended period.

Carbon monoxide poisoning

Gas appliances produce carbon monoxide (CO) as a byproduct of combustion. Although modern gas logs are designed with safety features like oxygen depletion sensors, leaving them on all night can increase the risk of carbon monoxide buildup. Carbon monoxide is a colorless and odorless gas that can be extremely dangerous or even fatal in high concentrations.

Energy efficiency

Leaving gas logs on when they are not needed wastes energy and increases your utility bills unnecessarily. It’s more cost-effective to use gas logs when you are present and can enjoy their warmth and ambiance.


How Long Can Gas Logs Stay On? 

The duration for which gas logs can safely stay on depends on the specific model and manufacturer guidelines. However, as a general guideline, gas logs are typically designed for intermittent use and not for continuous operation over extended periods.

Many gas log sets are equipped with safety features like oxygen depletion sensors (ODS) that monitor the oxygen levels in the room. These sensors automatically shut off the gas supply if the oxygen levels drop below a certain threshold, preventing the risk of carbon monoxide buildup. However, even with these safety features, leaving gas logs on for extended periods, such as overnight or when you’re not at home, is not recommended.

To ensure the safe and efficient operation of your gas logs, it’s best to use them when you are present and can monitor them. 

Can Gas Fireplace Logs Go Bad?

Gas fireplace logs do not have an expiration date but can experience wear and tear over time. They may become discolored or damaged due to exposure to flames and heat. Regular maintenance, including cleaning, is necessary to prolong their lifespan. 

While the logs themselves do not go bad, the gas components like burners or valves may require maintenance or replacement. If any issues arise, it is recommended to have a professional technician inspect and service the gas components. 


Going back to our main question of ‘do gas logs wear out,’ we can simply answer, yes, they will eventually wear out. Like every product we use in our lives, gas logs will wear out at some point.

The question of ‘how long they take to wear out,’ could provide you with a better answer for which gas log you might find better suited to your needs.
