Wood Inserts	If you love the traditional wood fire but don't like the heat loss and draftiness from your old open fireplace, the wood insert is for you. Most can be burned with the door open, allowing you to treat the insert like an open fireplace when desired. But with the door closed you'll convert that fireplace into a highly efficient heater. Some inserts are big enough to heat the whole house, though most are best used as a supplement to your central heat system.
	Pellet Inserts	Pellet inserts work the same as freestanding pellet stoves but they are specifically designed to convert your open fireplace into an efficient heat producer.
	Gas Inserts	In the same way that wood insert convert your fireplace into an efficient heater, the gas insert is best at returning the fireplace into a useful appliance rather than a negative heating proposition. Gas inserts have all the same benefits of wood inserts with the exception of open door burning. The flames are beautiful and the efficiencies can be as much as 80%. For smaller spaces and supplemental heat they are hard to beat. And no mess or hauling fuel.
