Can You Leave Electric Wall Heaters on All Night?
Generally, no, it is not safe to leave electric wall heaters on all night. From minor issues like flaky skin and dry nasal passages to more significant health concerns like carbon monoxide poisoning, it isn’t good for you to be in the room with a wall heater running overnight. If you aren’t present, that doesn’t eliminate the other dangers, such as an increased risk of fire. While some wall heaters may be safer than others, it’s never 100% safe to leave a wall heater on all night.
What Happens if You Leave an Electric Heater on All Night?

Not only does this damage your nose, but it also makes the membrane less effective, leaving your immune system more vulnerable. You can get stuffy and congested in mild cases, but long-term exposure can make you bleed. We can also get cracked lips, sore eyes, and flaky skin from dry air.

As well, any appliance running poses a chance of a stray spark, especially an appliance which generates heat. If the surroundings are hot and dry, that spark can catch and become a deadly house fire. It’s always safer to turn your electric heater off at night.
