It is recommended to have your chimney swept at least once per year, or more often if you use your wood burning stove frequently. Regular chimney sweeping can help to prevent dangerous buildup of creosote, a flammable byproduct of burning wood that can cause chimney fires if left unchecked.
In addition to having your chimney swept annually, it is also a good idea to inspect your chimney and stove regularly for any signs of damage or wear. This can include checking for cracks or other damage to the chimney, as well as inspecting the stove and flue for any obstructions or leaks.
If you use your wood burning stove frequently, or if you burn wet or unseasoned wood, you may need to have your chimney swept more often. It is also a good idea to have your chimney swept before the start of the heating season, to ensure that it is clean and ready for use.
Overall, regular chimney sweeping is an important part of maintaining your wood burning stove and ensuring that it is safe to use. By having your chimney swept at least once per year, you can help to prevent chimney fires and ensure that your stove is operating at its best.
