What is creosote?
Wood is never burned completely. Smoke contains unburned gases, vapors and tar-like liquids. These condense along the sides of the stove pipes or chimney and become a potentially flammable, crusty build-up called creosote.
Why is creosote a problem?
Creosote presents major problems to the wood burner. Creosote is corrosive to many surfaces. Creosote build-up acts as an insulating material which reduces the efficiency of your wood stove or fireplace. Finally, and most critical, creosote is flammable and presents a potential fire hazard.
What factors affect creosote build-up?
Many factors affect the rate and amount of creosote build-up:
- Type of wood burned
- Amount of moisture in the wood
- Type of fire burned
- Efficiency of stove. (One general irony of wood burning is that the better your stove or fireplace is at heating the house, the more creosote build-up it may have.)
- Location of flue
- Type of stove or fireplace
- Amount of use
How often should a fireplace be cleaned?
Because of various factors involved, there isn’t a general answer that is appropriate to all cases. Every fireplace/stove is different. Having it cleaned after you burn the first cord of wood is a great start to determine your cleaning frequency. If you notice back-drafting, or smoking or losing heat, you should certainly check for creosote build-up immediately. Periodic checking is essential for safe efficient wood burning.
How do I check for creosote build-up in my wood stove or fireplace?
Carefully open the damper and, using a flashlight, look up the flue. If the build-up is 1/8″ or more, a cleaning is needed. A trained chimney sweep can determine this more accurately and inspect all other safety issues.
