Pellet products are a great way to heat your home better. With hoppers that can hold up to 2 bags of pellets they are easy to load, and you don’t have to load more fuel as much as wood burning. On full loads you can experience up to 36-hour burn times! Pellet inserts take a two-pipe system. One for the exhaust and the other for air intake. Using a digital control board to set heat levels, feed trim speeds, and thermostat option these are easy-to-operate fireplace appliances.
