Frequently Asked Questions
1. Which is cheaper: wood pellets or firewood?
Firewood is generally cheaper per unit of energy. However, wood pellets are more efficient, so the cost difference is smaller than it appears.
2. Which burns hotter: wood pellets or firewood?
Wood pellets burn hotter and more efficiently due to low moisture and high density. Firewood has lower heat output per unit.
3. Which is better for the environment?
Wood pellets are generally better environmentally due to higher efficiency, lower emissions, and less smoke.
4. Which is easier to use?
Wood pellets are much easier to use—automated feeding, less labor, and more consistent heat. Firewood requires manual loading and more attention.
5. Do I need a special stove for pellets?
Yes. Wood pellets require a pellet stove or pellet boiler. They cannot be burned in a regular fireplace or wood stove.
6. Can I burn firewood in a pellet stove?
No. Pellet stoves are designed specifically for pellets. Burning firewood in a pellet stove will damage it.
7. Which requires more storage space?
Firewood requires much more storage space than wood pellets. Pellets are compact and easy to store.
8. Which is better for a primary heat source?
Wood pellets are better for primary heating due to automation and consistent heat. Firewood is better for supplemental or occasional heating.
