Is it okay to run a space heater all night?

No, it is not okay to run a space heater all night. It can be dangerous to have a space heater running in an enclosed area for long periods of time and may lead to a fire. It is recommended to not run a space heater for more than a few hours and to make sure it is in a well-ventilated area.
