  • Energy-Efficient FireplaceProviding Air SupplyOutside air must be provided to the fireplace or air from the room will leave through the chimneyClosable vents are commonly used to allow air to enter the fireplaceAir can also be taken from cold air returns

  • Energy-Efficient FireplaceUsing Heated Air EfficientlyLocating the chimney inside the structure will allow for radiant heat after the fire is outIncreasing the size of the firebox will allow more heatMechanical blowers are designed to pull air from the room and return it warmer

  • Energy-Efficient FireplaceDecreasing Chimney Heat LossDampers allow heat to stay in room when there is no fireDoors on the outside of the fireplace reduce the amount of air flow up the chimney

  • Chimney ReinforcementAt least four vertical 1/2 bars should extend from the foundation to the top of the chimneyRebar is added when the vertical steel is bent for a change in the chimneySteel anchors connect the fireplace to framing members
