Quick Answer
Mixing different types of pellets in a stove can be done but may affect burn efficiency and emissions. It's essential to consider the pellet's moisture content, density, and ash characteristics when combining them.
Choosing Pellets for Mixing
When selecting pellets to mix, look for those with similar moisture content, typically between 10% and 15%. Pellets with a higher moisture content can create steam and reduce burn efficiency. Wood pellets are generally a good choice for mixing, as they are widely available and come in various qualities. For example, a mix of 80% premium hardwood pellets and 20% economy-grade softwood pellets can provide a balance of heat output and cost.
Proper Mixing Techniques
To mix pellets effectively, use a 50-pound or larger container to minimize the amount of air that enters the mix. This helps to prevent the creation of steam and reduces the risk of fire hazards. When adding a new type of pellet to the mix, start with a small amount (about 10%) and gradually increase the proportion as you monitor the stove’s performance. A general rule of thumb is to limit the number of different pellet types to three to avoid affecting burn efficiency.
Important Considerations
It’s crucial to note that some pellet types, like those made from recycled materials or waste biomass, may not be suitable for mixing due to their variable composition. These pellets can release volatile compounds during combustion, potentially affecting indoor air quality. Always follow the manufacturer’s guidelines for the specific stove model and consult with the manufacturer before making significant changes to the pellet mix.
