There are different types of dampers for different functions. A ‘throat damper’ controls the airflow near the base of the chimney stack close to your firebox. It’s normally found in older stove designs, and requires occasional check-ups because it can become stuck or rusted. A ‘rooftop damper’ rests on top of your chimney (doubling as a chimney cap) and also opens and closes as needed. If your throat damper is no longer repairable (or desirable), it’s best to replace it with a more modern rooftop damper.
How do you control your rooftop damper? Take a look up your chimney! You should see a handle pointing down, and this is where you open the damper. When you light a fire, you must open the damper so that the smoke will go up the chimney and not out into your home.
When looking up your chimney, there’s a chance that you might not notice the fireplace damper at all, and if this is the case, you could be throwing away hundreds of dollars a year in heating costs. If your chimney damper is not working, not present, rusted or otherwise not in proper working condition, heat will escape up the chimney. An absent or malfunctioning fireplace flue damper is the number-one reason for heat loss source in homes.
