What makes a chimney draw?

A rising hot gas causes a pressure difference known as draft. This draws combustion air inside the appliance and expels the exhaust gas out. The chimney produces draft. Heat: The draft is stronger if the chimney's gases are hotter than the outside air.



How can I increase my chimney draw?

Heat the Metal Chimney

  1. You can roll a newspaper piece into a tube.
  2. Place the flame under the flue.
  3. After heating the flue system, light a fire in your firebox.
  4. Place a brick underneath each leg of your fire grate.
  5. Start a fire, and then check to see if smoke rises up from the flue.

Second, my chimney is not drawing correctly. The chimney must be cleaned. Creosote buildup in the chimney can decrease the flow of exhaust gases which can lead to fireplace smoke. Broken chimney flues can also lead to drafting issues. This fire will not generate enough heat to allow the chimney's draw well.

Also, ask this question: What causes a chimney draw?

The chimney pressure is usually less than the one inside the house. The draft effect is caused when the house air pushes air up the chimney from the inside.

Do taller chimney draw better?

Taller chimneys are better, because they provide a greater pressure differential due the higher column of warm air in the flue. Each cubic foot of this warmer ambient air is lighter than one cubic foot of lower temperature. Add them all. A 20-foot tall chimney draws twice the traffic than a 10-foot tall chimney.
