Is it okay to run a space heater all night?

No, it is not okay to run a space heater all night. The use of a space heater can lead to safety issues as well as unnecessarily increase heating costs if it is running for an extended period of time. It is best to only use a space heater for limited periods when necessary and to make sure that it is adequately ventilated.
