Best Gas Logs For Existing Fireplace

Can You Burn Real Wood in a Gas Fireplace?

You cannot burn real wood in a gas fireplace. Gas fireplaces are not designed to handle the process of burning real wood. Combustion is a complex process. It produces a lot of byproducts, including soot, smoke, ashes, and gases.

For a safe combustion process, one must ensure that the place where the combustion occurs has adequate facilities. There should be enough ventilation so that all the poisonous gases produced during the combustion process are eliminated. One must also ensure that soot and ashes are appropriately stored during the combustion process and regularly removed.

Sadly, your gas fireplace does not have any of these facilities. Its flue, firebox, and overall ventilation components are not designed to support the combustion process.

It is not a good idea to attempt to burn real wood in your gas fireplace. If you try to do this, you will be exposing yourself and others to various adverse effects.

Notably, the gas fireplace may catch fire because it lacks the necessary ventilation. The fire may quickly spread across the house and cause massive damages.

Also, if you attempt to burn real wood in a gas fireplace, your entire home may become full of smoke. Excess smoke will make everyone uncomfortable. It may also trigger severe allergic reactions in people who have breathing problems, including asthma.

When to Replace Your Gas Logs

Although gas logs are built to last for several years, this varies with various factors. The type of material used to make the gas logs determines how long they last and, eventually when you will have to replace them.

If you have ceramic gas logs, you will be assured that they will last longer than cement gas logs. Ceramic gas logs can withstand a lot of heat much better than cement logs.

If we assume that other factors are constant, you may have to replace your ceramic gas logs after about three or five years. It may be necessary to replace your cement gas logs after about two to three years.

Whether your gas logs are vented or not determines how long they last. If you have ceramic gas logs vented, you will not have to think about replacing them for at least ten years.

This length of time also depends on how well you maintain your gas logs. If you have ceramic gas logs that are ventless, you may have to replace them after about five years, even if you keep them well.

Therefore, replacing your gas logs depends on the type of material used to make them and whether they are vented or ventless.

Gas Logs vs. Gas Inserts vs. Gas Fireplaces: What is the Difference?

It is easy to be confused about gas logs, gas inserts, and gas fireplaces. All these three heating options have subtle differences that make every one of them suitable under specific conditions. You need to understand the differences to make the right decision.

Here are brief descriptions of every one of them.

Gas Logs

Gas logs are a stack of ceramic or cement logs that you place inside your standard fireplace. Gas logs have a burner that burns the gas to produce heat. The gas logs are designed to look precisely like real-life logs of wood. They are also of the same size as real logs.

There are two types of gas logs: vented and ventless. Vented gas logs use the existing chimney in your house to channel the exhaust from the combustion process. Ventless gas logs do not use the existing chimney in your home to remove the exhaust from the combustion process.

People tend to use gas logs primarily for aesthetics purposes. The heat that gas logs generate is much less than that created by other options, including gas inserts and gas fireplaces. However, gas logs are the cheapest option of the three.

Gas Inserts

Gas inserts comprise the actual heating element and two boxes. The smaller box houses the heating element, which burns the gas. The larger and outer box fits into your natural wood-burning fireplace.

Thus, gas inserts provide an effective way of converting your wood-burning fireplace into a more advanced and more comfortable to maintain a gas-burning one.

Gas inserts produce radiant heat by warming the air that is contained between its two boxes. The heat then spreads across the entire home over time. Due to its design and heating method, gas inserts produce more heat than gas logs.

Gas inserts may be vented or vent-free. You will need to use the chimney that is already installed in your home for vented gas inserts. Vent-free gas inserts operate without a chimney.

Gas Fireplaces

Built-in gas fireplaces do not need an existing wood-burning fireplace for their installation. Therefore, gas fireplaces are not modifications of existing fireplaces. A gas fireplace can be an excellent option for heating your home if you do not have an existing fireplace.

Gas fireplaces work just like gas inserts. They produce a lot of heat and use the radiant heating method to warm your home. In terms of heating capacity, gas fireplaces are the most effective option than gas logs and gas inserts.

5 Reasons Why Gas Logs Are A Better Alternative to Firewood

  • Easier to maintain. It is easier to maintain gas logs than traditional fireplaces that burn wood. If you use firewood in your fireplace, you will have to clean the place to remove soot and ash regularly. Doing this is not necessary if you have gas logs in place.
  • Gas logs are eco-friendly. Firewood comes from trees. The more firewood you burn in your fireplace at home, the more trees are cut to supply it. Sadly, trees take tens of years to grow. Therefore, using firewood is not an eco-friendly way of warming your home. Luckily, gas logs are made from ceramic or cement; their preparation does not interfere with the forests.
  • Gas logs are cheaper than firewood. Gas logs may last for years before needing to be replaced. New firewood logs must be inserted in your fireplace every time you need additional warmth in the home. Thus, it costs much less to use gas logs than firewood.
  • Gas logs are cleaner than firewood. Burning firewood produces a lot of smoke and other substances. The smoke may easily trigger massive allergic reactions in people who have breathing problems. Gas logs do not produce smoke and other similar substances.
  • Gas logs are visually appealing. Modern gas logs are very realistic and visually appealing. You can choose from a broad range of gas logs that resemble specific types of wood. Gas logs can genuinely enhance the ambiance and feel in your home.

Types of Gas Logs for Fireplaces

Gas logs can be categorized in terms of the materials used to make them or their mode of action. Based on materials, gas logs can either be ceramic or cement. Based on the mode of action, gas logs can either be vented or vent-free.

Vented vs. Vent-Free Gas Logs

Vented gas logs use the chimney in your house to channel the products of gas combustion outside. Thus, vented gas logs are used in houses that have fully functional fireplaces with chimneys.

However, a considerable amount of the heat that vented gas logs produce goes out through the chimney. Ventless gas logs do not need a chimney. The main benefit of using this kind of gas logs is that you end up with more heat than if you use vented ones.

Ceramic vs. Cement Gas Logs

Ceramic gas logs start to glow faster than cement gas logs. Thus, ceramic gas logs will give you heat instantly. Moreover, ceramic gas logs tend to last longer than cement gas logs. Therefore, you end up getting value for your investment if you purchase ceramic gas logs.

How to Choose the Right Gas Logs

Choosing the right gas logs can go a long way in helping you heat your home effectively and for a long time. The following are a few essential things that you should consider when choosing the right gas logs.

Fuel Type

It would help if you chose between logs that use natural gas and those that burn propane. There is not much difference in performance between gas logs that burn natural gas and those that utilize propane. Therefore, what you choose may be determined by the kind of appliances you already have in your home.

Fire Control Options

Gas logs come with different ways of starting and controlling the fire. The most basic control option entails the use of a key valve. The key valve can be on the wall or floor but outside the fireplace. Gas logs that have this control option can be lit using a matchstick. The gas valve lets you control the intensity of the flame.

Some gas logs have a standing pilot for starting and controlling the fire. The manual safety pilot comprises a knob inside the fireplace. You can use the knob to switch the gas logs on and off and control the burning intensity.

The most advanced gas logs come with remote control. You can use the remote control to adjust either some or all the functions of your gas logs.


Gas logs come in various sizes. You need to select the right size of gas logs to enhance the internal look of your home. Remember that the aesthetic value of gas logs is as important as their heating capacity.

Therefore, please measure the size of your fireplace and get gas logs that match it.

Gas Log Safety Tips

Although gas logs are relatively safe sources of heat for your home, they, nevertheless, pose a degree of danger. The most common risk of using gas logs is fire outbreaks. However, it is possible to use your gas logs safely by following these tips.

  • Install the necessary detectors and sensors. Oxygen Depletion Sensors and smoke detectors can help minimize the risk of fires. The ODS triggers your appliance to go off when the oxygen levels in the air decline. This prevents the production of poisonous carbon monoxide gas.
  • Carry out routine maintenance procedures. Let a technician regularly check your fireplace to ensure that the gas logs are in excellent shape. This will prevent accidents.
  • Evacuate the home if you smell gas or see that the color of the flame changes. Sudden changes in the color of the flame may indicate a severe problem. Also, when you smell gas, evacuate the house to prevent fire outbreaks.
  • Keep the kids away from your gas logs. Do not let the kids operate your gas logs. The kids can easily mess up with the appliance and expose everyone to danger.
  • Keep your chimney clean. Having a clean chimney always will minimize the amount of soot that is produced by your gas logs. The presence of soot and smoke can make your home very uncomfortable for anyone.

Why NOT Install Gas Logs on Your Own

There are several reasons why you should not install gas logs on your own. First, in many states, the law requires that only a certified technician installs gas logs and related heating appliances. Therefore, to comply with the law, let a certified technician do the job.

Second, installing gas logs and related heating equipment is a highly technical process. If any step of the installation process is not correctly completed, the consequences may be severe.

They may range from carbon monoxide and carbon dioxide gases leaking into your house to soot accumulating. Therefore, it is an excellent idea to let a technician complete the process for you.
