Concertina Pipes 1

I had to replace the original set of concertina pipes (they melted after I wrapped them in insulation).
The new ones came from Just Kampers in the U.K. by way of Bus Depot.

As I mention in my "Heat Mods" article, they are not of the same quality as the originals.

This year, as temperatures dropped, I turned on the heat and got basically nothing from either vent.

Upon removing the concertinas, I found they were both blocked.
