What does inadequate draft during wood burning lead to?

Inadequate draft during wood burning leads to hazardous creosote buildup. Draft is essential for maintaining proper air flow in wood-burning appliances; it helps to draw smoke and gases produced during combustion up the chimney and out of the home. When draft is insufficient, it can cause smoke and unburned particulates to remain in the combustion chamber longer than they should. This incomplete combustion leads to the production of creosote, a flammable residue that can accumulate in the flue or chimney. Over time, this buildup presents a significant fire hazard, as creosote can ignite and cause a chimney fire. Therefore, maintaining adequate draft is crucial for both safety and efficiency in wood burning.

The other choices do not accurately represent the outcome of inadequate draft. Increased heat output typically results from optimal combustion conditions, while excessive carbon dioxide is not specifically tied to inadequate draft but rather to overall combustion efficiency. Lastly, inefficient combustion is the result of insufficient draft, directly contradicting the notion of efficient combustion.
