Can You Leave a Wood Burning Fireplace on Overnight?

No, you should not leave your fireplace burning overnight. Leaving a burning fireplace overnight is dangerous. Not only could it put your house on fire, but could also be fatal for your family.

First, leaving your fireplace poses a serious fire risk, and it can also result in a buildup of colorless and odorless carbon monoxide. While carbon monoxide mostly occurs with gas fireplaces, it can also happen with wood fireplaces. Carbon monoxide could be a quiet killer if the vents in your fireplace are obstructed or otherwise not working properly.

Carbon monoxide is a gas that all fireplaces release. It’s a great practice not to leave a fire unattended, even if your fireplace should have ventilation measures to prevent carbon monoxide from entering your home.

On the other hand, the heat from your fireplace can cause an issue if you are not there to check it out. While it is rare for a gas fireplace to explode, it is possible if you are not careful.

Using a fire poker, distribute the embers and logs in the fireplace. For the fuel and embers to cool more quickly, you want them to be as open and flat as possible.

Use the spray bottle to apply water to the fire. Spray away until all of the embers and firewood are covered. In order for the wood and embers to cool and extinguish, you want everything to be wet.

Can You Get Carbon Monoxide Poisoning From a Fireplace? 

You can possibly get carbon monoxide poisoning, especially if your home doesn’t have proper ventilation to prevent carbon monoxide buildup. Especially for residents in the US, UK, Canada, and Australia, where the use of oval furnaces and fire heaters is rampant, carbon monoxide poisoning can occur.

An open fireplace can cause carbon monoxide poisoning. This is only one of the many reasons you should hire a qualified expert to do preventative maintenance on your fireplace and chimney. 

Your fireplace won’t be able to exhaust carbon monoxide effectively if your ventilation systems are obstructed or malfunctioning. This could result in a deadly buildup of carbon monoxide. The best way to prevent carbon monoxide poisoning if you have a fireplace is to get a carbon monoxide detector installed and ensure proper ventilation. 

Why You Should Open a Window When You Have a Fire in a Fireplace-Reasons

You don’t have to open your window if your fireplace has proper ventilation. Your fireplace needs proper ventilation for proper safety. There are reasons why you need to ensure proper ventilation. These reasons ranges from environmental to health and even safety purposes.

Below are a few reasons:

1. The Smoke 

Anyone who has used a fireplace will attest to how frightful it can be to start a fire only to have the room fill with smoke moments later. There are various reasons why this might occur, but one of them is because the chimney has ignited debris, such as leaves, acorns, twigs, soot, etc.

You should routinely arrange for a chimney sweep to check your fireplace. The presence of an open window will help keep the space from becoming overrun by odorous smoke.

2. To Prevent Carbon Monoxide Buildup

Another reason you need proper ventilation for your firehouse is because of carbon monoxide. The thing is carbon monoxide gas is odorless, tasteless, and unseen, and because of that it can be dangerous.

Carbon Monoxide could accumulate inside your home when using a fireplace, especially if your chimney is blocked with debris. In modern homes, which were probably built using airtight construction methods, an open window can assist in venting the gas. This is to ensure that the gas can escape. 

3. To Ensure Proper Airflow

To cut down on heat loss from your home’s furnace, slightly open a window, especially if you don’t have proper ventilation. This implies that your home will be warmed throughout even if your heating system is on and the fireplace is burning.

Carbon monoxide cannot be totally eliminated by opening a window. To properly ventilate your home and lower the risk of carbon monoxide poisoning, you should open more than one window.

You need enough air in your home when the fireplace is burning. You should open a window if you don’t have good ventilation. 

Should You Put Out the Fireplace Before Bed? 

Due to safety reasons, the fireplace should be put out if no one will be there to attend to it. Put out the fire when going to bed. Always extinguish any fire in your fireplace before retiring for the evening to avoid the possibility of both potentially fatal carbon monoxide problems and fires. 

The fire must burn out completely before you go to bed. The right gust of wind could reignite your fireplace even if you feel your fireplace is contained. Leaving your fireplace on can be hazardous. 

Ensure you put out the fire completely before turning off your fireplace for the evening. Additionally, confirm that the flue of your chimney is open so that air can flow and avoid carbon monoxide from accumulating. The front glass panels of your fireplace should be closed before going to bed. 

Use your fireplace poker to stir the ashes if you’re not sure if your fireplace has been completely put out. If any red-hot embers are still visible, your fire has not completely gone out and shouldn’t be left unattended. In this manner, there is less risk that a stray spark or ember may pop outside the fireplace and start a home fire. 


No, you should not leave your fireplace burning overnight. This applied to both gas fireplaces and wood fireplaces. While the chances of your fireplace causing a house fire are rare, it is possible. However, you can avoid risks by ensuring your fireplace is not left unattended.

Turn off your fireplace when you are preparing to go to bed. Using a wood fireplace, you can disassemble the logs and ensure they are no longer burning. Lastly, always ensure proper ventilation when using a fireplace in your home.
