Answer

Brief Explanations:

  1. Unvented space - heaters can produce carbon monoxide and other harmful gases and may not meet safety standards in local inspections due to the lack of proper ventilation for exhaust.
  2. Electric space - heaters are often designed to turn on automatically when the temperature drops below a certain level (such as freezing) as they can quickly respond to temperature changes and provide heat.

Answer:
