Portable space heaters are small, electric resistance heating units. Regardless of the shape, size or type of electric heating element found in an electric space heater, virtually all power drawn is converted into heat. The cost of operating an electric heater depends on how much heat the unit is delivering.ortable space heaters are small, electric resistance heating units.
