As a result of some lucky trading, we were able to pass on the truly massive stove that came our way, but which was way too big for the room, and get ourselves a shiny new Stanley stove for the living room. The gas bottle stove has gone back into the truck where it rightfully belongs, and works so well.
It was Christmas come early, as we lugged the box into the room to get it all unpacked, and a couple of hours and a lot of swearing later, it is installed and working beautifully. Living room is extremely toasty.
