Draft Dynamics: Designing Efficient Chimneys

Chimney performance dictates the overall efficiency of the stove by pulling smoke out of the living space.

Calculating Chimney Height

• The chimney must be taller than the roofline to prevent downdrafts.
• A minimum height of ten feet is recommended for open areas.
• Uneven terrain requires adjustments to the standard height guidelines.

Insulation Materials

• Insulated chimneys prevent heat loss and maintain high draft velocity.
• Clay tiles offer good thermal mass but require careful installation.
• Stainless steel liners provide superior durability in corrosive environments.

Good draft ensures that smoke is drawn out and not inhaled by the cook.
