A Simple Test:

I often use a simple test to gauge the ash content of my pellets. I burn a cup of pellets in a metal container outdoors. Once cooled, I can visually assess the amount and consistency of the remaining ash. Excessive clinkers or a large volume of fine ash indicates poor pellet quality.

Proactive Prevention: Choosing the Right Pellets

The battle against ash buildup begins long before you even fire up the stove. Selecting high-quality pellets is paramount.

Understanding Pellet Grades:

Pellets are typically graded as Premium, Standard, or Utility. These grades reflect ash content, heat output, and overall quality.

• Premium Pellets: These pellets have the lowest ash content (typically less than 1%) and produce the highest heat output. They are generally made from 100% hardwood.
• Standard Pellets: These pellets have a slightly higher ash content (1-3%) and may contain a mix of hardwood and softwood.
• Utility Pellets: These pellets have the highest ash content (over 3%) and are often made from lower-quality wood sources. I strongly advise against using these in a Cleveland Iron Works stove. The savings are not worth the hassle.

Key Indicators of Quality Pellets:

• Low Ash Content: Look for pellets with a certified ash content of 1% or less. This information is usually printed on the bag.
• High Heat Output: Opt for pellets with a BTU rating of 8,000 or higher. Higher BTU means more heat per pound of pellets.
• Low Moisture Content: Pellets should have a moisture content of 8% or less. Excess moisture hinders combustion and increases ash production.
• Consistent Size and Shape: Pellets should be uniform in size and shape to ensure consistent feeding and combustion.
• Clean Appearance: Pellets should be free of dust, debris, and foreign materials.
• Certification: Look for pellets certified by the Pellet Fuels Institute (PFI). PFI certification ensures that the pellets meet established quality standards.

My Pellet Selection Strategy:

I typically stick with premium-grade hardwood pellets from reputable manufacturers. While they may be slightly more expensive upfront, the reduced ash buildup, improved heat output, and longer stove lifespan more than justify the cost. I also like to try different brands to see how they perform in my stove.

Experimenting with Wood Types:

Different wood types produce varying amounts of ash. Hardwoods like oak and maple generally produce less ash than softwoods like pine. However, the manufacturing process and the presence of bark or other contaminants can significantly impact ash content, regardless of wood type.

Pellet Storage Best Practices:

Proper pellet storage is crucial to maintain their quality.

• Keep Pellets Dry: Store pellets in a dry, well-ventilated area to prevent moisture absorption. Moisture can cause pellets to crumble and produce more ash.
