Dampers amplify heat and lower energy costs.
Submitted by danA chimney damper is essential if you want to get the most heat possible out of your fireplace. If you don't close your damper before lighting your fire, the heat will escape right up the chimney. If you did not have a damper placed low in the chimney during your fireplace installation, you can still get the benefits of a damper by adding one on top of your chimney. You might feel like your fireplace isn't heating up your home quite the way you want it to - adding a damper might be the solution to this problem.
