I have a brand new THERMINOX 150mm diameter (inner layer) TWIN WALLED STAINLESS STEEL flu pipe for a woodburning/mutifuel stove. It has several sections as you can see, taking it through two 45 degree turns to step the flu over in a chimney breast. This flu can be built into a chimney or left exposed. I am selling it because we are now not building a chimney breast so need a different flu. It is brand new (6 weeks old). There is a small dent just below the top 45 degree piece but this is cosmetic and does not affect the joint. Here is a link to the manufacturers web page about this product:

This is a solid state piece of kit - top quality. Buyer to collect only as it is too bulky to send - and weighs a bit - (but a single person can pick it up ok). Fits in the back of an estate car. I will only accept cash on collection, or direct bank transfer. Please feel free to ask for more information The approximate length (being distance between parallel lines draw from the end face of the twin walled top and the face of the single walled base) is 1200mm .... this system is modular so this would form all or a substantial part of a longer run. It's on ebay at:
