The steam dies in the header and the near-boiler piping. The people freeze.

    I'd love to see the rest of the piping on that boiler, because what we can see certainly doesn't look proper. As for insulation, I saw one little bit, but where's the rest?

    Looks like a job for a Trap Header! You can't make dryer steam in these new smaller design boilers. Otherwise, a very cool demonstration of what's going on inside the piping. Noticed a lot of bouncing on the steam gauge. Water condition looked like it had a lot of impurities in it.
