Yes. There are standards for pellet quality, and the best pellets produce more heat with less ash and waste. “Premium” rated pellets have a reddish hue to them which indicates a higher content of Douglas fir wood, which is considered one of the best woods for pellet fuel. They have a higher BTU content than other woods and produce less ash. Pellets that are more golden in color are a cheaper pellet comprised of other woods that produce more ash and do not burn as clean. Check the pellets before you buy. Lesser quality pellets will cause you to burn more and clean your pellet stove more often.
