Wood pellets are an efficient and convenient biomass fuel, but how you store them can make a big difference to their quality. Whether you buy a few bags at a time or a full pallet, keeping your pellets properly stored will help ensure they remain in the best possible condition until you are ready to use them.
Why Do Wood Pellets Need to Be Kept Dry?
Wood pellets are highly absorbent. If they are exposed to moisture or damp conditions, they can begin to swell, soften and eventually break down into sawdust.
Once pellets have been damaged by moisture, they may no longer feed properly through your biomass boiler or pellet stove. This can affect performance and potentially lead to blockages or other issues.
Where Should You Store Bagged Wood Pellets?
Bagged wood pellets should ideally be stored:
- In a dry, covered and well ventilated area
- Off the ground, particularly on concrete floors where moisture may be present
- Away from leaking roofs, doors or areas prone to condensation
- In their original sealed packaging until required
A dry garage, shed or suitable storage area can work well, provided the pellets are fully protected from moisture.
Storing Full Pallets of Wood Pellets
If you order wood pellets by the pallet, it is important to plan where they will be stored before delivery.
Whenever possible, full pallets should be stored indoors in a dry location. Keeping the bags on the pallet also helps raise them off the ground and provides additional protection from damp surfaces.
If you need to store pellets for a longer period, regularly check the storage area for any signs of water ingress, condensation or damaged packaging.
What Happens If Wood Pellets Get Wet?
When wood pellets come into contact with water, they can quickly lose their shape and break apart. Even small amounts of moisture can affect the quality of the pellets over time.
If you notice a damaged bag, check the pellets carefully before adding them to your boiler or stove. Pellets that have become swollen, soft or crumbly may not be suitable for use.
Tips for Keeping Your Wood Pellets in Top Condition
Good storage is simple: keep your pellets dry, protected and off damp surfaces. Check bags for damage when moving them and avoid leaving them exposed to the weather.
Taking a little extra care when storing your wood pellets can help maintain their quality and ensure they are ready when you need them.
