How Long Do Gas Fireplaces Last?

On average, however, gas fireplaces usually have a life expectancy of 15 to 20 years and may need to be replaced after the second decade. But it’s not enough to approach this issue with a blanket method.

We’re going to go out on a limb here and assume you are absolutely enjoying your fireplace, especially if you live in an area where the temperature outside is around 10 degrees Celsius, or worse.

For people in these kinds of regions, fireplaces often become the most sought after home appliance, and for good reason. They are always utilized in the home and, occasionally, homeowners may erroneously leave them on overnight.

However, not all gas fireplaces last for the same number of years. Some may develop faults during the first decade of using it, while others may even exceed 20 years. This is not just a random occurrence.

There are specific factors that often influence the lifespan of gas fireplaces. These factors, if not taken into proper consideration could either decrease or increase the lifespan of your gas fireplace.

Top 3 Gas Fireplaces with Best Lifespan

Factors That Affect the Lifespan of Gas Fireplaces

These factors are pretty straightforward. For some of them, they are important qualities to look out for before you purchase and install the gas fireplace in order to guarantee longevity.

For others, you need to ensure you pay attention to them while using the fireplace to ensure a longer lifespan.

1. Ensure your Fireplace is Properly Installed

To be safe, request the assistance of an installation professional in order to avoid wrongful installation of the appliance, causing an unfortunate fire hazard in the future.

Other times, these fireplaces may be installed in a way that gives room for leaks, which may cause severe damage subsequently.

2. Maintenance

As with most home appliances, gas fireplaces require proper and consistent care in order to not only guarantee it being around for a long time, but to ensure it does not develop hazardous faults.

You are probably wondering if gas logs can eventually wear out, the simple answer is yes.

While you most likely will not need to replace your gas logs every other day as you may be required to when you are dealing with real firewood, you eventually will be required to swap out the gas logs for replacement logs.

When you eventually need to replace the logs, you do not need to change or replace any other part of your fireplace. By simply replacing the logs in your fireplace setup, you can easily get a general boost in your fireplace in terms of both aesthetics and its performance.

3. Types of gas logs

The type of gas logs used in your fireplace is also an important factor that can determine its lifespan. A fireplace with properly vented log sets made of ceramics and adequately maintained will have a much longer lifespan.

In most cases, these types of gas logs can last as long as 10 years and even longer before they may need to be changed. While for ventless gas log sets, their lifespan often ranges from 3 to 6 years but will need to be replaced as soon as it begins to wear.

4. Quality of materials

Typical gas logs that you may find in most homes are usually made of ceramic materials which fortify them against extremely high temperatures.

For fireplaces with cement log sets, you can bank on the fact that your log set will begin to fade after a short while, thereby losing its aesthetic value. The fireplace body itself will stand the test of time if it is made with quality steel materials.

5. Avoid placing objects or trash into the fireplace

Although this may seem relatively obvious, to avoid clogging your fireplace with debris or damaging the appliance altogether, avoid throwing dirt and objects into the fireplace.

How To Know If Gas Fireplace Needs to Be Replaced? (Warning Signals)

A gas fireplace can last as long as 15 years or even more if well maintained. Nonetheless, you should be vigilant to know if and when a replacement is needed whether or not you’ve enjoyed it for up to 15 years.

There are a few signs to tell when a gas fireplace needs replacement.

1. When repair becomes constant

You know a gas fireplace replacement is needed when you keep fixing the same or different damages over and over again.

2. The unit is out of date

Most gas fireplaces have a lifespan of 15 years. Once that lifespan elapses, the fireplace may begin to malfunction or become less efficient.

3. Unresolved Pilot Light Issues

This may be due to worn-out or damaged thermocouples. Where repair becomes impossible for some reason, a replacement is inevitable.

4. Lingering smell of sulfur or rotten eggs

This often indicates there is a gas leak. It is easily fixed when this leak is on the hose or pipe. You’ll simply turn it off and call in the professional to replace the pipe. However, when the leak is on the firebox, it may just require a replacement.

5. Presence of soot

While this may be normal in the wood fireplace, soot in the gas fireplace can indicate a major problem. Sometimes, especially when it’s the fireplace interior that has soot buildup, a replacement may just be the better option.
