A pellet hearth product burns processed wood, the logs have been debarked, ground, dried and then compressed into small pellets. Pellets generally are more economical than heating oil, propane or electricity, and like traditional wood, they are renewable. Compared with a log-burning product a pellet product is easier to use. You fill the hopper in the morning and get heat for 16 hours or more before you need to reload. The pellets burn cleanly and efficiently. They’re also more compact and thus easier to store than wood.
