In my house we have a gas fireplace, because we do not like running the heater and it saves money and the environment.
What i have noticed was the gas fireplace doesn't spread the heat around the room.
So i made a fan system out of a couple dead computer fans.
Step 1: What i Did
I took a three computer fans and hooked them up to a 12v converter, then i set them up so they would
push the hot air out of our gas log fireplace saving us money, and reducing my carbon foot print.
