at least one person found their gas fireplace they were hoping would heat them up when out of power didn't really work that well. I have a gas fireplace, it's vented to the outside through a chimney. If you sit right in front of it, you can feel a little radiant heat, but the true warmth comes from the electric fan that circulates air through the firebox that's heated from the gas flames. I'd always figured that if there was an extended power failure, I'd set up a 5V fan from my computer to blow air through the the fireplace. Some gas fireplaces are "direct vent", which means that they vent the exhaust right into the room. I'd never trust one of those not to fill the room with Carbon Monoxide.
