Nowadays, wood fireplace inserts are used the advanced combustion technology and was developed in both the United States and Canada in order to reduce emissions from wood stoves and to harmonize with the new environmental regulations. A secondary combustion was included in this new technology to make sure more complete combustion of the wood and smokes and also to increase the fireplace operating efficiency and to diminish the amount of emission escaping from the firebox.

The new wood fireplace inserts use two separated preheated path of combustion air, one of the air sources feeds directly into the wood burning and the other one is aimed above the main fire to capture and ignite the incomplete combustion gases that would otherwise be released up the chimney. 

The benefit from using double combustion air path:

• This two combustion air path simultaneous zone and flame patters in the wood fireplace insert
• Diminish the emissions by ten fold compared to a conventional  fireplace
• Release the low levels of creosote and incomplete combustion products, and eliminate the potential for chimney fires.

In order to allow much of the infrared heat to be transmitted into the room, wood fireplace inserts using advanced combustion technology included airtight, gasketed doors, and special ceramic glass windows.  And to allow easy viewing of the fire, a hot air blower used in turn to sweep the window with air. 

This new wood fireplace inserts have a better heat exchange property than conventional fireplaces because room air is drawn by a fan through a grill under the firebox then sent through a heat exchanger and back into the room at the top of the fireplace. In turn to send the heat to the rest of the house, the heat can be ducted to adjacent rooms where as auxiliary fan can send it through ducts.

The chances of combustion products leaking into the house are negligible as these wood fireplace inserts have such little interaction with the house air.  For better safety and effectiveness, the outdoor air is supplied directly to the fireplace for combustion and the maze that is used for preheating the air before it goes into the firebox is designed to keep the combustion gases from escaping. The levels of energy efficiency can be around 50% to 70% in a normal installation and when installed in a major living area with an open view to other parts of the house can be higher.  The insert can provide much of the heating needs for the entire house and also can reduce monthly heating bills.

The wood fireplace inserts provided the energy independence.  This wood fireplace insert can still operate as heat source for the house even with the power failure.  But the heat from the fire will spread out from the fireplace into the house by natural because the electric circulating fan will not run.
