Combustion Air Vents

Does your chimney ever have issues with smoke coming back into the home after the fire has been running for a while? The newer your home is the more your fireplace has to compete with other air sources for air for combustion. In addition to this new homes are tighter and let in less draft than older homes which can cause the fireplace to run our of combustion air and stop drafting. You can also experience this is you have an older home and you do something that changes the airflow in the home. Newer tighter windows, doors, or insulation can restrict the amount of airflow for the fireplace. When this occurs a combustion air vent is the proper solution to the  fireplace a fresh air source to pull from the outside air.

One additional benefit of the combustion air vent is not only does the fireplace draft better it also heats better. When the fireplace is pulling air towards the fireplace but also trying to push heat out the heat waves and air movement can interfere with each other. This leads to the heat bouncing back and fourth. If it pull air from the outside the fireplace pull the air forward from the rear of the fireplace and then pushes the heat out. The air and heat waves are moving in the same direction instead of opposing. There is a damper on the air vent so you can close it when not in use. A pilot hole is drilled from the firebox to the outside of the home. Then a hole saw is used to make a perfect round hole from one side to the other. There is a cover on the outside to keep any water or animals out of the fireplace.
