The blow down , when is done ?? Does boiler need to be on?

Nice explanation even though I could barely hear the audio. I also love the 1/2" for the vaporstat/pressuretrol and that they were far above the high water line. Quick question, is the lack of insulation for visual presentation only?

I created a core filled with water using a Fresnal lens to boil it inside the copper chamber but I noticed the water just surged up under vacuum and did not actually seem to boil. Thank you for the explanation as to why that happens. I cannot for the life of me figure out how to get the water to turn into steam under a vacuum, it just seems to want to continuously expand into the areas it can. Too much water perhaps?

I have one quick question for you and thank you for the video it was awesome is it necessary to pipe in a Hartford Loop when you have a one pipe steam system? Let's say all the radiators in the house have one pipe going to them thanks for your time
