What are Gas Logs

If you own a gas fireplace, you know economical and efficient it is. You may think these benefits have to do with the design of the fireplace and the fact it uses gas as fuel, but there is another important factor for getting the most out of your gas stove: your logs.

Gas stoves take the right logs to work properly. In this article, you will learn what these logs are, how they are unique, and how to choose the right ones for your home. You will also learn how to maintain your logs to get the most benefit for your dollar.

What are Gas Logs

Gas logs are ceramic or cement logs that look like real logs but without drawbacks. Wood logs can create sparks, smoke, and creosote, a sticky, tar-like material that sticks to your stove flute and can lead to a poor-functioning fireplace that increases fire risk.

Gas logs entirely avoid these issues and produce a consistent, more tame flame. All benefits combined make them a cleaner and safer option than traditional wood in your fireplace.

Types of Gas Logs

There are two types of gas logs: vented and vent-free. Each has its advantages and disadvantages. Let's review them here.

Vented Gas Logs:

Vented gas logs are the most popular. They are used with a vented fireplace and produce the most realistic flames. They are primarily decorative.

The main disadvantage of vented gas logs is that they are less efficient because the damper in the fireplace must remain open with a damper clip, causing heat loss.

Vent-Free Gas Logs:

Vent-free gas logs don't require a chimney or any other ventilation, which means they allow for more heat since they avoid the issue of needing the damper open. They take the inside air of your home, use it as combustion, and then release it back into the room.

The disadvantages of vent-free gas logs are that they look less realistic and create an odor while recycling your air which may create issues for people with allergies or sensitivity to odors. To reduce this issue, keep a window slightly open. They may not be used for extended periods.

Gas Log Add Ons

As you shop, you'll notice that some gas logs come with helpful add-ons, like crackling materials and varying flame options, to help you get the right look and feel you need. Do not use these on vent free logs.

Materials and Sizing for Gas Logs

You can choose between ceramic and concrete (aka cement) versions. Both have the look of real wood logs but also have key differences. Let's take a closer look.

Ceramic Logs

These logs are lighter, making them easier to install than concrete logs. They are also less prone to fading, helping you retain a better-looking fireplace longer. They are the most life like as they can glow.

As far as drawbacks, ceramic logs can break when dropped and are also more expensive than concrete logs.

Ceramic logs come in two types: refractory fiber and ceramic refractory. Refractory fiber logs are extra light and less expensive than ceramic refractory, but they are also more porous, which means they attract more odors, dust, and hair.

Ceramic refractory logs, on the other hand, are a mix of cement and ceramic, making them a heavier option. Of the two, ceramic refractory logs give off more heat and are more durable than the fiber option, but also come at a higher price. Refractory ceramic logs also last longer since they don't break down and don't cause odors over time.

Refractory Cement Logs / Concrete Logs

These logs can retain more heat and are cheaper than ceramic options. Since they are also heavier, they are less prone to moving around inside your fireplace when compared to ceramic logs.

One drawback is that the logs are heavy, making them harder to install. They also fade faster and are prone to cracking over time, which means they don't last as long. Often concrete logs last 2-3 years, whereas ceramic logs last 3-5 or as high as ten years.

The type of log you choose is a matter of personal preference. As for sizing for all these logs, most come in lengths of either 18 inches or 24 inches. Consider the size of your gas stove or fireplace before ordering. Also, some log types are recommended, so be sure to consult your manufacturer (i.e., Jøtul, Mendota, Vermont Castings, Kozy Heat, Fireplace Xtrordinair, etc.)

Maintaining and Replacing Your Gas Logs

Inspect your gas logs regularly. Look for any signs of damage, such as cracks or chips. If any are found, then replace them.

Also, clean your logs monthly; otherwise, they can attract dust and dirt that can later harm your gas fireplace. The best way to clean them is to vacuum them with a soft brush attachment and wipe them down with a damp cloth.

Gas Logs are a Thing of Beauty!

Gas logs are a beautiful way to aid with heating your home and are simple to install. Just select the style that offers the ideal heat and usability you want, and follow that up with periodic maintenance and cleaning to keep your fire cozy and inviting.
