125mm flexible liner choked with creosote and tar — burning unseasoned green wood, Harold Wood. Flue cleaned, condition reported, customer advised on fuel quality.
This 125mm flexible flue liner was choked with creosote and tar from burning unseasoned green wood — Harold Wood. The homeowner had no idea the flue was in this condition. This is the most dangerous outcome of burning wet wood: the tar and creosote build up silently inside the liner until the restriction is severe enough to cause smoke spillage, poor draw, or chimney fire.
Harold Wood properties — particularly the inter-war semis around the station and along the main roads — often have original chimney stacks lined in more recent years with flexible stainless steel liners. These liners are excellent when maintained correctly, but they must be swept annually and the fuel quality must be right. Wood must be seasoned for a minimum of two years before burning.
