Propane space heaters – propane is capable of burning very cleanly. Because of this there are propane space heaters that are approved for use indoors like the Mr. Heater F232000 MH9BX Buddy 4,000-9,000-BTU Indoor-Safe Portable Radiant Heater.

Piped gas space heaters and wood burners – as the name implies these are not entirely clean burning and will need an exterior vent to get smoke out of the building. Since they require an exhaust port they also lose the convenience of being portable. The advantage they do offer is that they can put out significant heat that it may be hard to find in portable versions.
