Indoor and outdoor wood-burning appliances and fireplaces may emit large quantities of air pollutants. Research shows that breathing wood smoke is not healthy. Wood smoke contains hundreds of chemical compounds, including nitrogen oxides, carbon monoxide, organic gases, and fine particles (also known as particulate matter or PM). Even limited exposure to smoke can be harmful to human health, particularly to the health of children, the elderly, and those with chronic conditions. Fine particles (i.e., particles smaller than 10 microns or about 30 times smaller than a human hair), can aggravate heart or respiratory problems, such as asthma, in people of all ages. More information on health effects of exposure to wood emissions is available at the EPA website http://www.epa.gov/woodstoves/

Wood Burning Primer

For many of us, the approach of winter evokes the image of pleasant evenings in front of a crackling fire. Toss on a few logs and sit back and enjoy the glow. Wood burning stoves and fireplaces have also become a popular alternative home heating source. There are indications that the average user makes a fire more than once a week and burns from 1/2 to 1-1/2 cords of wood per heating season. In this wood burning primer we will show you ways to improve your fireplace or stove usage and better enjoy the benefits they bring.

A wood fire can give your home a warm, cozy feeling, and in some cases can save you money. It can also affect air quality both indoors and out.

In many parts of Massachusetts, smoke from wood burning is a significant contributor to air pollution. Wood smoke contains toxic carbon monoxide, smog-causing nitrogen oxides, soot, fine particles, and a range of other chemicals and gases that can cause or worsen serious health problems, particularly among children, pregnant women, and people with breathing difficulties.

catalytic fireplaces are wood burning units that contain a device similar to the catalytic converter in a car. These devices are known as catalytic combustors and are also commonly referred to as "cats". These can come as fireplace inserts which are able to be installed into both pre-fabricated and masonry fireplaces.

The major purpose of this project was to design, fabricate, test, and evaluate a retrofit catalytic converter for woodburning stoves.^In the interim between our date of application March 5, 1981 and the beginning of the grant period December 1, 1981, several such devices became commercially available.^Therefore, we decided to modify the purpose and direction of our project.^In summary, we designed and constructed a calorimeter room in a building located on the campus of Northern Kentucky University.^We equipped this room with a woodburning stove and a metal chimney extending through the roof.^We designed and constructed the appropriate instrumentation for monitoring the heat output of the stove.^We observed and recorded the operating characteristics of this stove over a period of several days.^We then equipped the stove with a barometric damper and repeated the experiment.^We are now in the process of equipping the stove with a catalytic converter.^Thus the major emphasis of the project currently is to test and evaluate several commercial retrofit devices which are purported to reduce creosote and/or increase the efficiency of a woodburning stove.

The economics of heating your home with a wood stove have changed dramatically in the last few years.  In 2007 the cost of home heating oil went up over 97% and propane went up over 52%.  As a result, for many homeowners using a wood stove as either a primary or secondary approach for home heating may make a lot of sense (for more on this see the section on comparing fuel costs).  Moreover, wood stoves are good for the environment.  Not only are they carbon neutral, assuming the wood  was sustainably harvested, but in many cases they can be carbon negative.  This is because in many communities the wood comes from local salvage wood (tree work, dead trees, storm damage).  This wood would have been allowed to decompose (releasing carbon) or burned in an oil or natural gas  waste plant where even more energy resources would be wasted. If you harvested the wood from your own property even more energy is saved because fuel transportation costs are avoided.
