Dampers Allow Air In & Out of Your Chimney System

Your chimney damper is a simple mechanism that seals off the chimney flue when your fireplace is not in use. Dampers are made in several different designs. In most cases, dampers are located at the base where the chimney meets the firebox. Some are operated using a pull chain, while others are closed with a knob. The damper controls the draft of air traveling to and from the chimney flue. If you open the damper all the way, you will increase the amount of oxygen, creating a bigger, hotter fire. If you close the damper a little bit, you will reduce the airflow and calm the fire.  Learn more about top sealing dampers by watching the video below.

Chimney dampers serve several important functions, including:

  • Conserving energy by keeping the heated or cooled air from escaping your home via the chimney flue
  • Keeping animals and other debris from getting in your home by coming down the flue
  • Preventing rainwater and moisture from entering your home

Dampers clearly serve an important function for your chimney. An improperly installed or damaged damper can greatly reduce your energy efficiency, letting expensive heated and cooled air escape from your home by going up and out the chimney. If your damper isn’t functioning properly, it can also cause damage to your chimney. If water and moisture can get in, they can quickly damage your chimney, causing cracks in the mortar and other problems.

This company is one of the best around. Don't be fooled by some of these shady companies out there. I bought my wood stove from Total Chimney back in 2005. It is now 2009. The stove had a MFG defect that just showed now. Steve sent his crew over and repaired the stove with no questions asked. He stands by his products. I have used him since putting this wood stove in for the yearly cleanings as well. His crew does a great job and they are neat and full of knowledge about their products. They never leave a mess behind. I would not hesitate to buy another stove from Total Chimney. They stand by their products and really provide great service. I live out in Bethany and it gets cold! My stove heats my house just like Steve said it would. I couldn't be more pleased. He insisted I put the stainless steel chimney liner in with the stove. I was reluctant but this was money well spent. The stove runs very efficient and I sleep well at night knowing it was properly and safely installed. Be sure you line your chimney. It makes the stove run better and makes cleaning very easy from inside the hosue. 5 stars all the way!
