Wood-Burning Stoves, Inserts & Fireplaces

There are approximately 12 million wood stoves in homes today and 9 million of those are older, non EPA-certified stoves that are 50% less efficient than newer stoves. 

Energy efficiency benefits of replacing old wood stoves and fireplaces:

  • Saves money, fuel, time and resources.

  • Up to 50% more energy efficient.

  • Can use 1/3 less wood for the same heat.

  • Cuts creosote build-up in chimneys that helps reduce the risk of fire.

Environmental benefits of replacing old wood stoves and fireplaces with new appliances:

  • Reduces indoor and outdoor wood smoke pollution which has been linked to cancer, asthma and other serious health conditions. See health effects of wood smoke for more information.

  • Improved combustion efficiency reduces CO2, methane and black carbon emissions.

  • Saves billions in health benefits each year.



Fireplaces - Fireplaces can be either masonry fireplaces or factory-built fireplaces (also called prefabricated or "prefabs"). They are usually open face but most come standard with doors. 

A masonry fireplace is almost always built of bricks. There are some specialty types that are more exotic and use refractory materials, but 99.9% of them are made with bricks.

A factory-built fireplace is a metal box with refractory bricks inside manufactured to be framed into a house, without masonry. Sometimes they are gas fireplaces, but are often for burning wood. 

Insert - An insert can be put into any factory built open faced fireplace. It is important to remember inserts can only go into a fireplace that is built into the home.  

Stove - Freestanding unit. Usually installed in a central location with clearance around all areas of the stove. 
Can be used for cooking or heating.
