Pellet Inserts
If you don’t want to mess with the hassles of burning wood and are not a fan of gas then perhaps a Pellet Burning Insert is the way to add efficiency to your existing fireplace. A Pellet Insert burns wood pellets that are essentially compressed sawdust, it is a way to make use of the waste from saw mills. Some models can burn other biofuels as well including corn, wheat, and sunflower seeds. These units use forced air combustion and exhaust system so they do require a small amount of electricity and can even run on a marine battery in the case of a power outage.
