Amount of tar when cleaning chimney

[avio]

Did my annual chimney clean today and decided to weigh the tar/residue. It weighed 3 1/2 lb. I have an 8KW log burner lit most evenings throughout the winter and all day at weekends. Didn't weigh it last year but probably about the same. How does this compare to others. Thoughts!!!

only ever had 1 customer tell me his and when it was swept the sweep said guess you dont use this chimney its clean this after burning a full seasons logs.

Type of chimney will have an affect as well as wood. Throw hot gasses out into an unlined chimney and the cold stone will cause the gasses to condense onto the surface.

 

A liner warms up and prevents it. An insulated liner even less condensation.

I have an unlined chimney in a bungalow. I get at least 5 litres of soot every year. Beech logs dried for 3 years. Wet or dry do I care ? No life is too short its only bricks.

For info I have a double skinned 150mm liner and all the logs I burn have been seasonsed for at least one year.

I've had half a bucket burning anything and i mean anything from the cheapest dirtiest coal you can imagine to pallets. Unlined 1930's chimney. Just burn it very hot for an hour a day to get rads upto temp

Sadly not everyone's chimney is in as fine a state as yours. Friends can't sell their house at the moment as tar has leaked through the chimney breast onto an upstairs bedroom wall. Surveyor's report highlighted the dangers of gas etc. They're looking into lining but they fear they'll need to knock chimney down and rebuild to satisfy future surveys.

Just swept mine . No tar just a small amount of soot , about an inch or so in a bucket .
