Pellet stoves are generally considered safe, but they do involve certain technical and user-related risks. The most serious risk is carbon monoxide leakage, which can occur due to blocked chimneys, improper installation, or insufficient airflow. Because many pellet stoves rely on electricity, power outages may disrupt combustion control. Using low-quality pellets can increase ash and soot buildup, reducing efficiency and raising the risk of chimney fires. Poorly maintained stoves may also emit higher levels of fine particles. From a fire safety perspective, the stove must be installed at safe distances from combustible materials, in accordance with manufacturer guidelines, and maintained regularly. Most risks can be effectively managed through proper system design, certified installation, routine maintenance, and informed daily use.
