Conclusion. While electric space heaters can help keep room temperatures warm, they can also be dangerous and cause fires. Space heaters should never be left unattended or used within three feet of any combustibles and should always be plugged directly into an outlet.
The duration for which you can leave a space heater running depends on the time of day and your specific needs. During the Day: It's safe to leave your heater on for 6-8 hours if you're in the room. If you're busy or moving between rooms, consider using a timer to automatically shut it off after a few hours.
Always turn off the heater when you leave the room. Extended use of heaters can make them break down internally, and they could catch fire. Plus, you waste energy when the space heater is keeping an empty room warm. To be on the safe side, look for a space heater that has automatic shutoff features.
