The default ruling regarding leaving an electric heater on while sleeping is permissibility, unless there is harm in doing so. If there is harm, it must be removed, based on the Prophet's (peace be upon him) saying: "There should be no harm nor reciprocating harm." He also commanded extinguishing fire before sleeping, as stated in the : "Indeed, this fire is an enemy to you. So, when you sleep, extinguish it."
