Big liner

My beautiful fiancée trundled off this morning to do horsey things along with the dogs and I headed for Stromness a little later to deal with a faulty immersion heater. Job done I came home and did a bit more stuff to our boiler room - the chimney is now clear of birds nests and I have cored out a hole for the ventilation ducting to run through.
I decided that I would blip something boiler room related, mainly because I haven't taken any other pics. This is the flue liner which I need to fit in the newly cleared chimney.
