Store pellets in a cool, dry place in airtight containers to prevent moisture absorption and maintain their quality and efficiency for heating or cooking.
Proper pellet storage ensures optimal performance for pellet stoves, grills, and smokers. Whether you use wood pellets for heating or cooking, moisture control is the most critical factor. This guide covers everything from container selection to long-term storage solutions.
Why Proper Pellet Storage Matters
Wood pellets absorb moisture easily, which causes several problems:
- Expansion and crumbling that jams augers
- Reduced heat output and inefficient burning
- Mold growth that creates unpleasant flavors
- Potential fire hazards from self-heating
The Pellet Fuels Institute recommends maintaining pellets below 10% moisture content for best performance.
Best Containers For Pellet Storage
FDA-Approved Airtight Bins
Food-grade plastic containers with tight-sealing lids are ideal. The Traeger StayDry Bin (22 lb capacity) is specifically designed for pellet storage with these features:
| Feature | Benefit |
|---|---|
| Airtight gasket | Blocks humidity |
| Rectangular shape | Space-efficient stacking |
| Flavor labels | Easy identification |
Original Packaging With Modifications
For short-term storage (under 3 months):
- Keep pellets in original bags
- Place bags on pallets with cardboard barrier
- Cover stack with moisture-resistant tarp
Indoor vs Outdoor Storage
Indoor Storage Locations
Basements
Excellent option if dry and temperature-controlled. Maintain at least 12″ clearance from walls.
Garages
Only suitable in arid climates. Use airtight containers even for unopened bags.
Outdoor Storage Solutions
When indoor space isn’t available:
- Choose elevated, well-drained areas
- Position away from trees and structures
- Use double-layer waterproof covers
- Check monthly for moisture intrusion
Seasonal Storage Considerations
Winter Storage
Protect from snow melt and ice formation. Add silica gel packets to containers.
Summer Storage
Prevent self-heating by:
- Limiting pile height to 4 feet
- Providing adequate ventilation
- Monitoring internal temperatures
Specialty Pellet Storage Solutions
For large quantities (2+ tons):
- Install dedicated pellet silos
- Use bulk bags with desiccant systems
- Consider automated feed systems
According to Traeger’s research, proper storage can extend pellet shelf life from 6 months to over 2 years.
Common Storage Mistakes To Avoid
- Storing near heat sources (water heaters, furnaces)
- Leaving pellets in grill hoppers during wet weather
- Using damaged or non-airtight containers
- Ignoring visible moisture in storage areas
By following these guidelines, you’ll maintain pellet quality and ensure reliable performance from your pellet-burning appliances season after season.
