Can You Leave An Electric Fireplace On All Night?

Due to the nature of their electrical components, electric fireplaces can, in theory, be left on indefinitely. The only condition is that the fireplace must be attended to at all times during operation. Therefore, it isn’t recommended to leave an electric fireplace on all night while you sleep.

You should never leave an electric fireplace running throughout the night if you aren’t going to be monitoring constantly it while it’s on. 

This is true in spite of the fact that electric fireplaces are the safest type of fireplace, compared to traditional types such as gas or wood-burning fireplaces. While traditional fireplaces burn real fuel to create a real fire, electric fireplaces are entirely powered by electricity. 

The flames are not a real fire, but instead an illusion created by LED lights and mirrors on the inside of the fireplace. This mechanism creates realistic-looking flames without the necessity of actual burning fuel. The heat that an electric fireplace produces is generated by an internal heating element, typically being a fan or infrared heater. They heat up a room in a similar way to how a conventional space heater functions. 

Therefore, electric fireplaces should be treated with the same care as you would with any other type of heating appliance. The fireplace requires enough ventilation on all sides of the unit to prevent it from overheating. It should be plugged directly into a mains outlet or hardwired into your home electrics, never into any kind of extension cord or power strip. And lastly, you should never leave an electric fireplace unattended, especially if you intend to leave it on all night. 

Why Can’t You Leave an Electric Fireplace on All Night? 

As we’ve stated, electric fireplaces are a very safe option compared to other traditional types of fireplaces. As they lack a real fire, they pose significantly less of a fire risk to your home. You don’t need to keep attending to them and adding fuel to keep them running as they are completely powered by electricity. 

On top of this, many electric fireplaces come with built-in safety features that cause the unit to shut off automatically if it exceeds a safe temperature. With that being said, electric fireplaces are not entirely without their safety concerns. While the flames in these fireplaces are completely harmless, the issue lies with the units’ heating element.

Heating elements in electric fireplaces typically use one of two technologies; either a fan-forced or infrared heater. Fan-forced systems use air inlet and outlet vents to take in cool air and blow it over a heating element, before expelling the warm air back into the room. Infrared systems instead use infrared technology to radiate heat into a room. 

Both of these types of heating elements draw a lot of power during operation and can become very hot to the touch after prolonged periods of use. If left on throughout the night while you’re sleeping, the electric fireplace could overheat and start a fire. This is also why you should never leave your electric fireplace unattended at any time while the heater is on. 

Can You Leave the Flames of An Electric Fireplace on Overnight?

Although you should never leave the heater of your electric fireplace running overnight, you could potentially leave the flame effect on. Many models of electric fireplaces come with a flame-only feature that enables you to switch the flame effect without running the heater. 

Again, the flames on an electric fireplace are only an illusion of light and therefore produce no heat of their own. So, in theory, you could safely leave the flame effect switched on overnight if your fireplace has this functionality. However, we recommend switching the fireplace off overnight regardless. 

You won’t see the flames while you’re sleeping, so leaving the unit switched on would just be a waste of energy usage. This is on top of the minimal potential risk that the unit may still malfunction given that it’s connected to a live power source. As best practice, turn your electric fireplace off every time you leave it unattended, including when you go to bed.  

How Long Can You Leave An Electric Fireplace On?

In theory, you can leave an electric fireplace on for as long as you wish. This is on the condition that you will be monitoring the fireplace at all times during its operation, switching it off every time you are going to leave it unattended.

If you want an electric fireplace that will maintain a constant temperature in a room over a prolonged period of time, you should choose a model that features an integrated thermostat. Units that have thermostatic control allow you to set a certain temperature that you want the room to be; the fireplace will then heat the room up to the desired temperature, switching itself off and on automatically to maintain the temperature throughout operation.

Leaving Electric Fireplaces On Overnight: Conclusion

The bottom line is that you should never leave an electric fireplace on overnight if you’re going to sleep while it’s operating. This is underpinned by the rule that you should never leave your electric fireplace unattended during operation at all times. It is possible to leave the fireplace’s flames on overnight if your fireplace features a flame-only feature. However, for your safety, it’s best practice to switch the entire unit off completely before going to bed.
