I put a hand in front of the gas fireplace grill and felt a cold breeze. Caught ya you little energy napper!
You can easily solve this problem if you have a wood burning fireplace by just closing the damper. Boom. Problem solved. Unfortunately, I have a gas burning fireplace and the dampers on a gas burning fireplace are permanently kept open.
Since we only use the fireplace during power outages and for entertaining, I wondered if there was a way that I could close the damper when it wasn’t in use to keep the heated air from escaping up the chimney, and save money on my utility bills, and reduce my natural gas usage.
Fortunately, you can stop drafts in a gas fireplace with a Chimney Balloon, or Chimney Pillow . It looks like a Mylar balloon that that you stuff up your chimney when it’s not in use. You can buy one of those or make your own version.
Do I have to even have to tell you that I made my own DIY version? Of course not.
