Gas heaters are available as vented and vent free models. Using a gas heater in a room that just doesn't warm up, even with a central heating unit, is just one of the reasons they are so popular. Generally they will heat the space faster, use less energy and allow you to keep the desired temperature more easily than a central unit. And, in case of a power outage a gas heater will continue working, though if you have a thermostat attached, that will not work without power.
Vent free or ventless heaters do not vent air to the outside of the house, nor do they draw outside air into the house for combustion. Air needed for combustion is drawn in from the room where the unit is housed, thereby losing virtually no heat in the process, and allowing it to operate at 99.9% efficiency.

Vented gas heaters draw their oxygen from outside the home and remove carbon monoxide through exhaust pipes. Because much of the heat goes up the vent, they are not as efficient as vent free models.
As far as the safety of vent free units, first of all, a proper installation by a certified technician is key. Because these heaters do create carbon monoxide, why risk your life and that of your family by having a gas heating system installed by someone not qualified. Vent free units come with an oxygen depletion sensor which alerts you when the level of oxygen drops to a dangerous point. Along with this safety feature, you can protect yourself by having a carbon monoxide detector, making sure it is in good working order. Please be sure to check you local codes before purchasing a vented or vent free gas heater as there are some states and municipalities which do not allow vent free gas heaters or have limitations on their use.
For example, the Empire DV-210-SG vent free gas heater, where codes permit, can be used in bathrooms, and the SR-10 is allowable for bedroom use. Vented Gas heaters are frequently used in garages and workshops. Some can be mounted on the ceiling, like the Modine Hot Dawg Garage Heater. Available in several BTU sizes, they are certified for residential, industrial or commercial use.
