Gas Fireplace: Why Does It Remain Warm Even When Not In Use? How To Deal With It?

Gas Fireplace: Why Does It Remain Warm Even When Not In Use? How To Deal With It?

When your gas fireplace is off, do you still feel the warmth? We’ve got you covered if you’re unsure whether this is a typical circumstance. We did some research to see if you could maintain your composure in the face of a gas fireplace that never gets cold.

Despite not being in use, a gas fireplace can stay warm thanks to the pilot light’s heat-emitting properties. The glass door panel and gas insert typically maintain a warm temperature.

A gas fireplace is a great heating and relaxing appliance. We shall discuss the conditions of a gas fireplace after use in this article.

We will also look at its attributes, solutions to problems, workings, safety advice, and other issues. Continue reading while savoring the warm atmosphere created by your fireplace.

Why Does My Gas Fireplace Feel Warm Even When It Is Off?

The pilot light in a gas fireplace causes it to remain hot even after being turned off. This tiny flame, which can be blue or yellow, produces a lot of heat. It works tirelessly to eliminate the requirement for re-ignition prior to using the furnace.

How Warm Ought A Gas Fireplace To Become?

The characteristics and brand of a gas fireplace affect its power. There is therefore no ideal temperature. You may customise it based on your preferences and the weather. Between 7,000 and 60,000 British Thermal Units, or BTUs, of energy can be released.

A Gas Fireplace May Become Too Hot

Applying too much fuel might cause a gas fireplace to overheat or overfire. The fire is able to grow upward as a result. The temperature is higher than what the manufacturer has advised. For instance, the temperature ranges from 1000 to 1500 degrees Fahrenheit.

Overfiring may result in discomfort rather than warmth. Typically, it leads to structural damage, equipment malfunction, and health dangers. For instance, it may result in carbon monoxide poisoning and chimney cracks. A carbon monoxide detector should be installed, according to fire experts.

Is My Gas Fireplace Too Hot? How Do I Know?

If you notice a warping firebox, a black stain on the glass, or hear popping noises when the gas fireplace is operating, it is too hot.

You can discover that the flue pipe has creosote accumulation when you clean it.

You should be aware of these warning signs so that you can handle them by determining the source.

A gas fireplace can heat up too much for the reasons listed below:

  • Air vents that are completely open improve ventilation.
  • Exceeding the stove’s maximum wood load capacity.
  • Large stove has a large heating inclosure.
  • The worn-out gasket, a barrier against abrasion and air confinement, causes panel doors to badly seal.
  • Draft has too much power.
  • Logs have an excessive amount of moisture.
  • Unlike wood logs, ceramic logs heat up quickly.
  • An improperly installed fireplace causes heat and pollutants to escape.

Overfiring affects the atmosphere, but it can also harm a fireplace’s interior components, especially the baffle plate at the firebox’s tip.

How Can My Gas Fireplace Be Cooled Down?

Implement one or more of these recommendations to cool down your burning gas fireplace to prevent degeneration from the inside out:

  • To lower the oxygen level, reduce or reposition the air vent space.
  • Limit the amount of wood you burn per round to two or three logs of a reasonable size.
  • To reduce smoke and creosote production, start a fire that is proportionate to the stove’s surface area.
  • Before starting, properly close the door, and if there is a leak, replace the gasket.
  • Use a stove fan, heat deflector, or poker to open the panel and let the air flow.
  • Ceramic logs and wet wood should not be burned.
  • Install a tight-sealed damper to control the airflow and serve as a chimney cap.

Should You Touch A Gas Fireplace When It’s Hot?

Yes, even after cooling down, the gas fireplace might still feel warm to the touch. It can cause varying degrees of skin burns, just like other heat-producing devices. The glass and metal components, such the mantel or hood, should be avoided. Children should not be near it.

If you have a vent-free gas fireplace, use caution. The combustion gases carbon monoxide, nitrogen oxides, and vapour are free to travel throughout your home because it lacks a cavity to release them.

Despite the fact that the entire house should have proper ventilation, this stove might lead to moisture issues and poor air quality.

The gas fireplace can operate continually, but it shouldn’t be left on all night. This is dangerous. The glass panels of your fireplace should be sealed, and the vents should work properly. Otherwise, up to three hours is the safest operation period.

You can look at the manufacturer’s recommendations. To maintain safety, you should also plan routine maintenance with chimney professionals. Remember that unattended gas fireplaces may be both expensive and dangerous.

Can You Add A Thermostat To A Gas Fireplace?

A gas fireplace can have a thermostat added to it. Thermostat controls enable the flame rate to be changed. They make it simple for the user to adjust the temperature. Consequently, you can quickly avoid overheating. There are many different sorts of thermostats, but you want to pick one with a millivolt system and a sizable digital display with a backlight. Low electrical voltage should be sufficient for the thermostat, making installation simple. You can reach the thermostat with a remote control or by pressing the touchscreen buttons.

Can A Pilot Light Be Left On In A Gas Fireplace?

All gas fireplaces, whether they are electric or stand-alone, have a pilot ignition. The latter immediately puts out the fire whereas the former burns continuously unless you turn it off.

Long-term gas consumption is considerable in the continuous light’s standby mode. To operate, it needs up to 1500 BTUs.

While there is no power, it still functions. In contrast, the latter uses less energy because combustion can be restarted automatically.

For these reasons, whether it is in a warm or cold season, it is recommended to turn off the pilot light when you are through using it. This will help you save money and conserve energy.

Do not forget that the flame is not always there. Modern models, unlike older ones, feature periodic pilot light systems, but they don’t always give forth a glow.

On A Gas Fireplace, How Do You Turn Off The Pilot Light?

Here are simple techniques for putting out a pilot light.

  • It is necessary to turn the gas valve to the “off” position. The moment the gas reserve is turned off, the flame will go out.
  • You can either crank the dial or pull a tiny lever to release the mechanical block. It stops inadvertent power-offs.
  • Make sure the thermocouple has cooled before cutting the power. This part serves as protection in the case that the pilot light blows out.

To open the valve, the thermocouple needs to be sufficiently heated. Release the manual control to put out the flame safely. If you smell gas when lighting the pilot, don’t press the ignition button any further.

Pilot Light Issue

A pilot light’s most frequent issue is when it continuously going out. The gas fireplace is unable to maintain its light as a result.

Examine the gas supply to rule out it being a possible reason before replacing any components. Another potential cause is a good draught.

Resetting the pilot assembly and inspecting nearby components like the thermocouple and thermopile are your last resort. If not, you must replace the components.

The thermocouple is necessary for the pilot light to operate properly. The flame also behaves improperly when it develops faults or alignment issues. Even if other components are in good shape, you will need to overhaul them because replacement parts typically come in sets.

On A Fireplace, Where Is The Thermocouple Located?

Next to the pilot light is the gas fireplace’s thermocouple. It resembles a little pipe with a sharp end. The gas valve is connected to it by a copper wire.

Look to see whether the pilot system is dirty if it won’t stay lit. Scrub the thermocouple with a paper towel or sandpaper to clean it. After that, use a multimeter to check the voltage. A value of between 25 and 35 millivolts is considered good.


The gas insert and glass door panel of a gas fireplace typically stay warm even when not in use. The pilot ignition system is always turned on, which causes this.

Although this flame is essential to the fireplace’s ability to heat a room, it is a good idea to be aware of when and how to properly turn it off. In order to avoid mishaps, you should ultimately keep your distance from any surfaces near an active fireplace.
