A pellet stove is designed to burn wood pellets efficiently, providing heat while maintaining fuel economy. However, if you’ve noticed that your pellet stove keeps feeding pellets more frequently than expected, it can be a cause for concern. In this article, we will explain the technical reasons behind this issue, helping both technical and non-technical users understand why it occurs and how to address it.
Airflow Issues:
Solution: Check for obstructions in the venting system and the combustion blower. Clean or replace clogged air intake filters. Ensure that the exhaust pipe is clear and not obstructed.
Improper Pellet Quality:
Solution: Invest in high-quality wood pellets with low ash content. Inferior pellets can leave behind excess ash, triggering more frequent auger feeding.
Faulty Thermostat or Temperature Sensor:
Solution: Check the thermostat’s settings and calibration. Ensure that the temperature sensor is clean and functioning correctly. Replace or recalibrate them if necessary.
Combustion Issues:
Solution: Clean the burn pot and the heat exchanger regularly. A dirty burn pot or heat exchanger can disrupt the combustion process, causing the stove to feed pellets more often.
Inadequate Draft:
Solution: Verify that your venting system is installed correctly and complies with local building codes. A strong draft is essential for efficient combustion. If needed, consult a professional to evaluate and adjust the venting system.
Incorrect Auger Settings:
Solution: Review your stove’s user manual and adjust the auger settings according to your specific heating requirements. A setting that’s too high will feed pellets more frequently, while a setting too low may not provide sufficient heat.
Worn Auger or Motor:
Solution: Inspect the auger and motor for signs of wear or damage. If they are malfunctioning, consider replacing them. Regular maintenance can prolong their lifespan.
Conclusion
Understanding why your pellet stove keeps feeding pellets excessively is essential for maintaining its efficiency and your comfort. By addressing the technical issues mentioned above and following proper maintenance and operation guidelines, you can resolve this problem and enjoy the benefits of a well-functioning and economical wood pellet stove. If you’re uncertain about any technical aspects, it’s advisable to consult a qualified technician for assistance.
