Air purging questions come up a lot here, so

Wow, that's a lot to take in...That is a great way to take care of it all. I had to study it for awhile to understand. That is a big step in advancing how to purge systems.

The boiler outlet piping that goes behind the heating boiler circ may confuse some people. I really don't know how to correct this (other than pointing it out on the drawing maybe?). Most wallies would easily figure it out, but I'm not sure about the newbies.

Thanks for sharing your knowledge (sorry about the rambling, I haven't had enough coffee yet :-)

I have a drawing

I will include in my Jan PHC News article, on air purging products and methods.

I'd love to hear some feedback on this piping.

This should purge all piping, radiant loops, and circs.
