Chimneys require attention and maintenance to ensure safety & efficiency in every aspect. Exhaust, soot or creosote, or any type of debris may collect over time increasing the danger of chimney fires, as well as the heating system within your house.
But how often should you clean a chimney? It depends on the use, the type of fuel used and the surroundings. In this guide, we’ll discuss a few factors to provide insight to the user about how to clean your chimney.
General Rule: Annual Cleaning for Most Chimneys
It is suggested by National Fire Protection Association & CAmP, that in addition to annual inspections, you should regularly clean and maintain all chimneys and fireplaces, also venting for blockages and animals.
Usage Frequency and Type of Fuel Are Factors
Wood-Burning Fireplaces
Wood-burning fireplaces tend to have chimneys that are actively used and tend to accumulate dirt or ash on their walls. Such chimneys also need to be cleaned more regularly and frequently so it does not get clogged. Creosote is a very combustible substance that accumulates on the inside of the chimney walls.
More frequent cleaning is necessary as creosote accumulates whenever a fire is made in the fireplace. When using it regularly, it is advisable to clean it once every 50 – 70 fires.
Gas Fireplaces
Gas fireplaces keep the soot levels low when compared to wood, so the amount of waste produced is very low. However, they tend to get clogged more often. From time to time, gas fireplaces will vent some amount of fog, which shows buildup on the inner chimney linings. Yearly inspection by experts who know how to clean your chimney is advisable.
Pellet Stoves and Oil-Fired Heating Systems
These pellet stoves generate a lower amount of creosote but will accumulate ash over time, which will interfere with airflow. It is also advisable to clean them before commencing the heating season to avoid the spread of stale ash, smoke, and odor from releasing on the initial start-up.
Signs Your Chimney Needs Cleaning
Strong Odors
This is when the fireplace has a distinct smell that is pungent and filled with smoke. Such smells could be red flags as they signify creosote is present.
Trouble Lighting the Fire
This could mean that the chimney is choked up with soot or obstruction.
Creosote or Soot is Accumulating
If the chimney material has black-brown, tar-like material, it should be cleaned very soon.
Animals Nests
Nests from birds or squirrels may block parts of the chimney and present danger.
Smoke in the Room
Presence of smoke in the house indicates that the smoke is unable to properly vent, possibly due to a dirty chimney.
Letting the Pros Handle How to Clean Your Chimney
Failure to schedule routine chimney examinations may lead to situations that pose a risk, including chimney fires, emission of carbon monoxide, etc. Most chimneys should receive a minimum of one inspection every year. The frequency of cleaning depends on usage, type and quantity of fuel, and even climate conditions.
Regular cleaning not only prevents risks but also increases the efficiency of the fireplace, ensuring that the house is adequately kept warm and safe during the cold seasons.
