Indoor Fireplaces and Woodstoves

Once a main source of heat for most homes, wood burning fireplaces and stoves have largely been replaced with more efficient means of heating with less impact to local air quality. However, many homes in our community still utilize indoor wood burning appliances. Uncontrolled smoke and odor emissions from wood burning appliances can have negative impacts on those around us, especially those with existing respiratory illness, children, and older populations. 

Beginning in 1986 and with updates in the 1990s and 2010s, the City adopted Air Pollution Nuisance Code and requirements for solid fuel burning appliances in response to growing concerns of poor regional and local air quality and its impacts to public health. In addition to defining certain emissions as a public nuisance, these ordinances regulate the types of fuels and appliances that may be used within city limits.  

What You're Breathing

What You're Breathing

Smoke contains very small particles easily absorbed by the body.

 

Woodsmoke may smell good, but it's not good for you. The biggest health threat from smoke is from fine particles, also called fine particulate matter or PM2.5. These microscopic particles can get into your eyes and respiratory system, where they may cause burning eyes, runny nose, and illnesses, such as bronchitis.

Fine particles can make asthma symptoms worse and trigger asthma attacks. Fine particles can also trigger heart attacks, stroke, irregular heart rhythms, and heart failure, especially in people who are already at risk for these conditions.

Example of a "Brown Cloud" over Denver impacting visibility.

 

Fort Collins is not immune to the pollution of big city life. One out of every four days, the City violates the State of Colorado's visibility standard, causing a dark haze or "brown cloud." While wood smoke contributes to the brown cloud, it can be more impactful in the specific neighborhood where wood burning occurs.

Build a Better, Safer Fire

Build a Better, Safer Fire
 

An efficient fire requires good firewood, using the right wood in the right amount, and good fire building technique. Get the best efficiency from your wood stove or fireplace using the following tips:

  • Season wood for at least six months.
  • Store wood outdoors, off the ground, with the top covered.
  • Wood burns best at a moisture content of less than 20 percent. Test wood with a wood moisture meter before you burn it.
  • Start fires with newspaper, dry kindling, or all natural fire starters, or install a natural gas or propane log lighter in your open fireplace.
  • Buy and burn locally cut firewood to decrease the risk of transporting invasive forest pests to your property.
