Why line and insulate your chimney?
Ways to reduce tar and soot build up in your chimney
- Always connect a stove to an insulated chimney (as per building regulations)
That means using double skin insulated flue pipe, insulated flexible chimney liner, or pumice chimney liners.
- Regularly have the chimney swept - at least once a year before the start of the burning season.
- If burning wood then a second sweeping in the middle of the burning season is advised.
- When burning wood only burn seasoned wood.
- Regularly have hot fires - once a day - this will help to dry out the tar that has built up. You can also occassionally burn dry untreated skip wood as this has a very low moisture content.
- Use Calfire chimney clearner addative - a non zinc based addative that helps tar flake off the chimney - available from FiresnFlames chimney cleaner page.
- Do not use salt or zinc based addatives as they can corrode the chimney.
All these recommendations will help to reduce the amount of tar build-up in the chimney and therefore the risk of having a chimney fire. These recommendations should be used together, only implimenting one of these recommendations is not enough.
